1. Introduction
The authors of present work concentrated their
efforts on rhenium and its alloys. This metal has some
specific properties and finds its application in various
fields of semi-conducting industry. In recent years a
sphere of using these compounds was substantially
widened space technique, electronics, IT sector and so
on. There was also emerged a necessity to investigate
their physical and chemical properties and to elaborate
effective technology of getting alloys basing on these
elements. There are some works and patents
describing methods of obtaining rhenium shining
metallic sediments cited in the references [1-40].
Substantial mechanical strength, hardness, high
electrical impedance and other properties of rhenium
alloy rhenium and its alloys to be widely used in
various fields of technique. Alloys of rhenium with a
range of metals are used in electronic, electrometrical
and atomic technique as well for production of special
coatings [1-9].
There are various methods for obtaining thin films
of rhenium semi-conducting alloys. But the analysis
of known methods of obtaining rhenium
chalcogenides’ thin films showed that the most
perspective and less expensive is electrochemical
method which has those advantages, that it does not
need sophisticated equipment, high temperatures and
allows to produce an alloy of high purity. Using this
method it is easy to control thickness, a composition
of a coating, and, varying electrolysis regime, to get

coatings with demanded composition[14, 15] The
purpose of this paper is to summarize, organize and
view publications for 20-30 years and to identify
trends and opportunities of modern electrochemical
methods (voltammetry, potentiometry, ammeter, etc.)
for producing rhenium alloys. The survey provided
more than 100 works devoted to the preparation of
rhenium alloys by electrochemical method. Review
article also includes the new works on
electrodeposition of chalcogenide rhenium by the
electrochemical method from different electrolytes.
The present work was made aiming to research the
appropriate processes, to determine scientific base of
electro-deposition of rhenium chalcogenides and to
define physicochemical properties of produced thin
films. The electrodeposition of metals is one of the
main sections of electrochemistry having great
practical importance. Sphere of application of
electrolytic metals constantly widens due to rapid
growth of technique. Nowadays it is hard to name a
field where electrolytic metals and alloys are not
presented.
2. Electrodeposition of Rhenium and Its
Alloys
The electrodeposition of metals is carried out both
from water solutions and non-water organic and melts
environments. Main regularities of electrodeposition
of metals from water and organic environment do not
differ substantially. But it is possible to deposit from
melted environment those metals which do not
separate from water solutions (vanadium,
molybdenum, tungsten, zirconium and other). Metallic
rhenium and it’s alloys have unique physico-chemical
properties, due to winch find wide application in the
most important fields of modern technique [1-10].
Rhenium alloys with metals of platinum group can be
used for production of electric contacts having high
operational properties. Distinctive property of rhenium
is its resistance to electro-corrosion that prevents
burning of contacts.
Further is opening a new field for application of
rhenium-oil refining industry, in which rhenium in
combination with platinum is used as catalyst in oil
reforming processes for production of high octane
benzenes. The application of rhenium-platinum
catalysts prolongs a life period of catalyst five times
and raises the process effectiveness more than by 60%.
Simultaneously the octane number of produced
benzene rose to 100-105 units. Thus the application of
catalysts of mentioned type provided a new quality
jump in oil refinery. Thin coatings of rhenium
disulphide were offered as catalyst for alcohols
dehydrogenization process. Mostly interested are new
reports about works in the field of application of
rhenium and its alloys for needs of air- and rocket
industry. Not less interesting and important may be
considered the application of rhenium in nuclear
technique [7, 11]. The rising consumption of rhenium
stimulates a searching of new sources of raw, effective
methods of its refining, development of new methods
of production of rhenium and its alloys.
Hot sulfuric acid reacts with rhenium, transforming
it to HReO4. Rather easily rhenium dilutes in bromine
water at slight heating. Rhenium vigorously reacts
with halogens. It forms simple and complex
halogenides and oxyhalogenides. Rhenium
halogenides present interest for technologies and
analytical chemistry, because they are volatile. The
purification of metallic rhenium from impurities by
the method of rhenium purification after its
chlorination is based mostly on volatility of rhenium
chlorides.
Rhenium reacts with sulphur, selenium, tellurium
and forms sulfides, selenides and tellurides [2]. With
selenium rhenium forms following compounds:
Re2Se7, ReSe2, ReSe, Re3Se2. In rhenium-sulfur
system there was defined occurring of rhenium
sulfides ReS, Re2S2, ReS2, Re2S5, ReS3 and Re2S7.
Rhenium sulfides and selenides are effective catalysts
for hydration of organic materials. Their advantages in
comparison with metallic catalysts of platinum group

consist of that they are not poisoned by sulfur
containing compounds. Rhenium sulfides also
catalyze redox reactions of NO and N2O at the
temperature of 100 °C. Besides mentioned fields of
application rhenium can be used in analytical
chemistry (as a reagent for potassium, for fractured
crystallization of rare earth metals as it is generally
known [3-10], rhenium is deposited from sulfuric,
ammonium-sulfuric, phosphatic, oxalic, citric, alkaline
and other electrolytes. The investigation of the
process of electrodeposition of rhenium, one of trace
chemical elements, has practical and theoretical
interest [1-5, 8-10, 21].
The group of Chilian scientists studied rhenium and
rhenium oxides being obtained by electrodeposition
from alkaline perrhenate electrolyte in a standard
electrochemical cell (cathode and anode). The Cu
substrate was used as the cathode, with an apparent
surface area of 13 mm2, whereas the Pt electrode was
the anode, with an apparent surface area of 1 cm2. The
galvanostatic electrodeposition was conducted with a
5 A-30 V GW rectifier (model GPC-3030D), which
also allowed cell voltage measurement. Regarding
rhenium and rhenium oxide electrodeposition was
related to the use of an aqueous acidic electrolyte
(NH4ReO4 or HReO4 dissolved in H2SO4) and in some
cases preparing and electrolyte by dissolving metallic
Re in hydrogen peroxide. The authors found that on
the zone near the edge of the dendrite of the
electrodeposited material, it is possible to ascertain
that the mechanism of electro crystallization involves
the reduction of Re (7+) from the ReO4¯ ions to
metallic Re (0) throughout the successive reduction of
ReO3 (6+) to ReO2 (4+). It is possible to
electrodeposit rhenium rhenium and rhenium oxides
from alkaline aqueous electrolyte without evident
formation of powdery deposits [24].
In the works [25, 26] there were synthesized and
studied electrochemical and photophysical properties
of a thin coating of Rhenium.
In the monograph [27] the methods of extraction of
rhenium from raw and secondary materials, obtaining
metallic rhenium and products from it are described.
Special attention was paid to extraction-sorption
processes, having dominating position in rhenium
metallurgy. Specific examples of existing
technological schemes of rhenium extaction from
various kinds of materials and their equipment design
[27] are given.
In Uruguay the comparative study of
electrochemical and optical properties of rhenium
deposited on gold and platinum was carried out [28].
Rhenium-containing films were grown on gold and
platinum after different potentiostatic and
potentiodynamic polarizations in the 0.20 V to 0.70 V
range (vs rhe) in aqueous acid perrhenate
The method [29] involves placing the stent in a
series of rinsing and electroplating solutions, one
containing radioactive rhenium (186Re, 188Re, or
both).The overall processing time is 15 min and the
procedure may be conveniently applied just prior to
the stent insertion. The plated stent contains
radioactive rhenium in a 1.2 microm-thick cobalt layer,
with an outer 2 microm layer of gold.
Electrochemical oxidation of silver and rhenium
electrodes in molten LiF-NaF-KF eutectic at 600 °C
was investigated by cyclic and convolutional
voltammetry [30].
Yakovlev M.A. [31] studied modeling and
optimization of the processes of extraction of rhenium
from multi-component alloys. It was defined that
when anodic dissolving alloys on the base of nickel,
rhenium, nickel, cobalt, aluminum and chrome
practically fully go into solution, tungsten and
molybdenum go as tungsten and molybdenum acids
and tantalum and niobium go to sludge.
L.G. Holz [32] in the PH.D thesis named “The
voltammetric determination of rhenium in raw and
anthropogenic materials” for the first time determined
and interpreted peaks, observed on anodic and
cathodic voltammetric curves in the processes of
The Electrochemical Deposition of Rhenium Chalcogenides from Different Electrolytes

electrochemical transforming of perrhenate ions in
acidic electrolyte background on graphite electrod for
the first time he proposed to make the calculation of
the concentration of perrhenate ions by stripping
voltammetry (SVA) method not by current peak but
by total area under electropositive peaks depending on
ions concentration in the solution. The scientists from
Hungarian Academy of Sciences have shown that the
chemical nature of electrodeposited rhenium species
depends on the H2SO4 concentration in the supporting
electrolyte from which the deposition takes place [33].
A smooth Au electrode with about apparent surface
was used as a working electrode. In order to eliminate
impurities and traces of rhenium, the gold electrode
was an one with about 0.5 A for 10 -15 s in 0.5 M
H2SO4.
In the co-operative work of Chilian and Spainian
researchers rhenium thin films were prepared by
electrodeposition from an aqueous solution containing
0.1 M Na2SO4+ H2SO4, pH 2 in presence of y mM
HReO4 [34].
In Tel-Aviv University, Israel, there was carried out
the electrodeposition of rhenium tin nano-wires [35].
The effects of bath composition 34 mM NH4ReO4,
12-93 mM SnCl2, 12-93 mM Mg(SO3NH2)2·H2O, and
343 mM H3C6H5O7 (citric acid, anhydrous) of
operative conditions were investigated, and chemistry
and structure of the coating were studied by variety of
analytical tool. A Re-content as high as 77 at % or
Faradaic efficiency as high as 46%, were attained.
The formation of gold nanoelectrode [36] arrays
was investigated by electrodeposition of the metal
along the pores left on directionally solidified
NiAl-Re eutectics by selective dissolution of the
rhenium fibre. After the necessary pre-treatment for
the passivation of the NiAl matrix and dissolution of
the rhenium fibres to create arrays of nanopores
(diameter ~400 nm), the electrodeposition of gold into
the pores was initially investigated by examining the
growth of the deposits with the application of the
cathodic pulses.
According to the literature data [37], for obtaining
rhenium coatings the electrolytes containing fluoride
estimated to be more preferred compared with a
sulfate electrolytes. From these electrolytes rhenium
coatings on electrodes of copper, molybdenum, and
stainless steel may be deposited.
The authors [38] investigated the processes of
electrolytic production of rhenium coatings from the
electrolyte KCl-NaCl-ReCl4 with a current density
5-200 mA/cm2 at 680-970 °C. At this process the
dense coating of rhenium is forming, having thickness
20-40 microns and length up to 10 m. The diffusion
coefficient of Re4+ ion at 790 °C is 2.8 × 10-5, at
840 °C-3.5 × 10-5 cm2/sec.
The process of rhenium electrodeposition was
investigated by the method of measurements of
charging curves, measurements of overloading of
rhenium discharging and hydrogen on it, as well as by
defining a structure of sediment (by X-ray and
electron-microscopic methods). The authors [10, 11]
made a conclusion that in the process of
electrodeposition rhenium is saturating by hydrogen
(14-22 atomic%), main part of which is discharging at
room temperature and only 0.5 at % at > 500 °C. The
author [10] supposed a physical and chemical sorption
of hydrogen with formation of intrusion phases thru
ReH hydride. The electrodeposited metallic rhenium
has thin-dispersed structure and high tension (to 1,500
kg/cm2). There are known alloys of rhenium with
many elements, obtaining mainly by thermic method.
Alloys of rhenium with tungsten, molybdenum,
chrome, nickel and some others have a range of
valuable properties: high melting temperature, high
specific impedance, low volatility, heat fastness and
others. The valuable properties of rhenium alloys
allow applying them in most critical parts of various
equipment as well as for coating of electric contacts
and other parts, working in hard conditions [20, 21].
In connection with this the electrolytic production of
some rhenium alloys is a question of a great interest.
The works [20, 21, 41-76] were let in on the processes
The Electrochemical Deposition of Rhenium Chalcogenides from Different Electrolytes
189
of electrodeposition of rhenium together with other
metals on solid cathodes. Meyer A. [77] showed
probability of electrodeposition of alloys of rhenium
with a number of metals (Ni, Co, Fe, Zn, Cr, Pd, Rh,
Ag, Au) on platinum cathode. In such conditions a
discharging of hydrogen is lowering to 80%. The
sediments have good quality.
From one side, a rising of alloy may be explained
by rising of hydrogen discharge overstress at alloy
comparing with discharge it at rhenium [48]. From
other side resulting to alloy formation the enthalpy
(ΔH0) and free energy (ΔG0) change which obviously
have negative values.
A probability of joint electrodeposition of rhenium
and metals of ferric group were shown in works [1, 48,
49].
A special attention is to be paid to the works of L.M.
Netherton and M.L. Holt [76] in which was shown
probability of obtaining alloys Re-Ni and Re-Co with
various content of components depending of rhenium
concentration in electrolyte with high output by
current. They proposed two kinds of electrolytes
having following compositions: 225 g/L NiSo4·7H2O,
45 g/L NiCl2·6H2O, 1 g/L KReO4, 30 g/L H3BO3, to
second solution was added also citric acid in amount
of 70 g/L. From electrolyte with first composition (Ph
= 4.6) irrespective of current density an alloy was
deposited with high output by current (96-100%) and
with low content of rhenium. From second electrolyte
(Ph = 2.6), on the contrary, content of rhenium in
alloy achieved 60%, but output by current was 50%.
Alloy Re-Ni with 85-90% of rhenium also deposits
from electrolyte proposed in [21]. The electrolyte
contains 15 g/L KReO4, 5 g/L NiSO4, 50 g/L
(NH4)2SO4 and has pH = 2.5-3.0. At temperature
70 °C and current density 2-4 A/dm2 a coating
deposits with output by current ~90%. The alloy
Re-Ni in this electrolyte can be deposited only under
certain combination of pH and current density. In the
work [21] successfully was obtained the alloy Re-Ni
(85-90% of rhenium) with output by current 90% in
the electrolyte containing: KReO4-15 g/L;
NiSO4·7H2O-5 g/L; (NH4)2SO4-50 g/L, under pH =
2.5-3.0, current density 2-4 A/dm2 and temperature
70 °C with in dissolvable anodes. High output by
current connected with rise of overloading of
hydrogen due to co-deposition of nickel.
Were used ammonium-sulfate electrolytes having
various compositions [49, 68, 77]. Was defined
influence of current density, temperature,
concentration of rhenium and metal of ferrous group
to the process of electrodeposition two-component
alloys Re-Fe, Re-Ni, Re-Co. Was shown that a rise of
current density within the limits 2-20 A/dm (50 °C)
leads to rise of rhenium content in alloy. The
electrodeposition of alloys under optimal current
density (5 A/dm) promotes obtaining of shiny coatings
with output by current of alloy 100%. Particularities
of Re-Ni cathodic electrodeposition process were in
details highlighted in the works [48, 49]. The authors
highlighted that the mechanism of electrochemical
discharge of rhenium from perrhenate anion especially
with other metals is not clear, that impedes
development of optimal technological regimes. The
process of forming an alloy by the method of
polarization curves measurements was investigated,
chemical and phase composition of the alloy was
defined, output of alloy by current was calculated. The
authors came to the decision that nickel is discharging
with substantial depolarization in comparison with
separate discharging of metals. For rhenium discharge
also mitigates and the depolarization is 20-200 mV.
When investigating a possibility of obtaining of
triple alloy rhenium-nickel-chrome were used
electrolytes for obtaining of double alloys
rhenium-nickel, rhenium-chrome [11]. The obtaining
of triple alloy rhenium-nickel-chrome was proceeded
by group of Russian scientists [9].
During the investigation electrolytes for obtaining
defined double alloy were prepared and was added a
salt of appropriate third component. As a result of
series of experiments was defined that shiny coatings
The Electrochemical Deposition of Rhenium Chalcogenides from Different Electrolytes
190
of triple alloys are obtaining only in chrome-rhenium
bath in which was added nickel sulfate. The quality
alloys coatings containing: rhenium-0.5%;
nickel-0.28%; chrome-4.5% were obtained from the
bath of following composition (g/L): KReO4-50,
(NH4)2SO4-40, H2SO4-75, CrO3-15, NiSO4-45.
For electrodeposition of alloys Re-W the authors
Sominskaya Z.M. and others [9, 43] recommended
solutions on the base of perrhenate and tungsten with
addition of H2SO4 and (NH4)2SO4. As a complexion
agent which ties tungsten to soluble complex they
added citric acid. Alloy Re-W in a form of solid coating
or powder separates from solution containing potassium
perrhenate and ammonium (6-60 g/L of rhenium),
sodium tungstate (3-32 g/L of tungsten) ammonium
sulfate (50-200 g/L and citric acid (100 g/L). Maximal
output by current as in acidic so in alkaline conditions
is 10% and content of tungsten in alloy is 3%. The alloy
with maximal concentration of tungsten (10%) was
deposited with output by current ~1%.
Were also obtained alloys rhenium-copper with
various composition [9, 11]. A dense coating of
Re-Cu alloy containing 50% of copper is possible to
obtain in concentrated by rhenium electrolyte with
composition: 50 g/L KReO4 + 75 g/L H2SO4 + 40 g/L
(NH4)2SO4 + 1 g/L CuSO4. At the current density 100
A/dm2 and temperature 75 °C were obtained coatings
containing 36% copper. Alloys Re-Cu containing
2.4-3.0% of rhenium were extracted from electrolyte
with composition: CuSO4-125 g/L; H2SO4-45 g/L;
NaReO4 200 g/L at temperature75 °C and current
density 1-2 A/dm2.
To get the alloy Re with Cu authors [50] used
sulphate electrolyte. The gold and titanium electrodes
were used as cathode. Were studied rentgen graphic,
electron microscope and X-ray diffraction analyses
(ЕDХ, ХRD, SEM [50].
The authors of work [51] investigated the
mechanism of co-electrodeposition rhenium-nickel
alloy on copper backing from bath containing citric
acid.
For obtaining of coatings Re-Ir-Ni [52] a deposition
was carried out from various aquatic solutions on
copper backings with three electrodes by galvanostatic
method. The bath contained of iridium chloride,
ammonium perrhenate, nickel sulfamate and citric
acid.
The alloys of rhenium with nickel also had got the
authors of work [53]. For it was used three-electrode
cell, the polarization curves were measured in
galvanostatic conditions. The electrolyte had in
composition ammonium perrhenate, nickel sulphate
and citric acid. Was studied a mechanism for
nickel-rhenium alloys.
The authors of present work [54] were obtained
rhenium alloys with iron group (Me = Ni, Fe and Со).
The electrolyte had composition as follows:
ammonium perrhenate, nickel or cobalt sulfamate,
iron sulphate and citric acid and magnesium
sulfamate.
In their previous works authors reported about
co-electrodeposition of rhenium and metals of iron
group. In the present work [55] the authors in more
details investigated a mechanism of
co-electrodeposition.
Rhenium also was produced from secondary
materials containing rhenium and superalloy of nickel
clearly highlighted in work [56]. Were investigated at
constant potential electrolyse thin coatings CuIIRe at
electrolytic reduction CO2. The reduction products
were analyzed by FTIR and gas chromatography-mass
spectrometry. Were also studied out triple alloys on
indium-tin oxide coated by glass substrates from
acidic peroxo-polymolybdo-perrhenate solution.
Triple alloy Ni-Co-Re was investigated in alkaline
environment and their kinetic parameters were
determined. The authors [60] in this study gave data
on the production and use of rhenium and its alloys.
Rhenium-nickel alloy was also obtained by authors
[61]. Was investigated an influence of temperature,
current density, composition of electrolyte on alloy
composition. The electrolyte has the composition as

follows: ammonium perrhenate, nickel sulfate and
citric acid. For it was used electron microscopy (SEM),
X-ray diffraction (XRD) and X-ray fluorescence
(XRF).
A magnetic material based on
cobalt-nickel-rhenium-tungsten-phosphorus
(Co-Ni-Re-W-P) composition has been developed by
electrochemical deposition [62]. With proper control
of process conditions, hard magnetic films with high
out-of-plane remanent magnetization (Mr) of 3.11 kG
and coercivity (Hc) of 2.33 kOe are achieved.
Fabrication of Co-Ni-Re-W-P in the form of
microcylindrical arrays of ~50 µm diameter and 90
µm height enhances the vertical anisotropy to a
vertical Mr of 5.15 kG and Hc of 2.02 kOe. The
materials and fabrication technique of microstructures
as reported could be applied for the fabrication
technique of microstructures as reported could be
applied for the fabrication of magnetic
microelectromechanical systems. [62] The authors [63]
prepared from aqueous solutions with citric acid as
complex forming agent on a surface of Cu-substrate
coatings Ni-Re-P (Re = Ce, Nd). At 385 °C with the
amount of rhenium 30% (weight %) were obtained
amorphous coatings. Rhenium films with various
amount of copper were obtained. Qualitative deposits
Re-Cu (50%) were obtained from concentrated
solutions of rhenium: 50 g/L KReO4 + 75 g/L H2SO4
+ 40 g/L (NH4)2SO4 + 1 g/L CuSO4. At 75 °C, 100
A/dm2 were obtained films with 36% Cu. From the
solution CuSO4 -125 g/L, H2SO4-45 g/L, NaReO4-20
g/L at 1-2 A/dm2 were obtained films with
concentration of rhenium 2.4-3% Re.
For the obtaining rhenium-copper film was
proposed the electrolyte CuSO4 + NH4ReO4 [64]. At
the potentiostatic mode were obtained foils
rhenium-molybdenum and rhenium-tungsten coatings
[65]. The composition is 96% of H2SO4, potential-5-6
V, current density-60-70 mA/sm2.
The work [66] was dedicated to investigation of
some electro-physical properties of thin electrolytic
films of rhenium chalcogenides, as dynamic and static
voltammetric characteristics (VAC). Authors
investigated a typical VAC of diode structure
measured in static regime and found that diode
structure has polar-dependent switching effect. In
electrolytic layers of Pt-ReХe2-Al2O3 type, this effect
occurs right after supplying of voltage on diode
structure. The diode structure showed properties of
bi-stable switching. Were also investigated dynamical
characteristics of diode structure Me-Re-Хe2. The
investigation of VAC in dynamical regime has great
interest for interpretation of phenomena forming the
switching effects. Data obtained in present work
showed that the structure based at thin films of
rhenium chalcogenides, has VAC with S- and
N-shaped sectors of negative impedance (NI) both for
direct and reverse current direction. In contrast of
other devices with NI the elements basing on
mentioned alloy have simple production technology
and can work at wide range of temperatures. This
property let us suggest that devices basing on thin
films of rhenium chalcogenides may find wide using
in various devices in telemechanics, automation
computing technique.
At the conference which has been held in the
Moscow 2013 our work “The electrophysical
properties of thin films of rhenium chalcogenides
obtained by electrochemical method” was presented.
Our results found confirmation in the works by L.
Agapova and V. Guro [67-68].
3. Methods for obtaining alloys in system
Re-X (X = S, Se, Te)
The obtaining of chalcogenides can be performed
by various methods, defined by physics-chemical
particularities of synthesized compounds and initial
matters.
For obtaining of chalcogenides are used various
methods: (a) direct synthesis from elements by
alloying; (b) absorption from gaseous phase; (c)
obtaining of chalcogenides from salts solutions; (d)

electrochemical method [69-75]. Practically are using
all abovementioned methods. In the works [76-84]
widely were studied the system Re-X (X = S, Se, Te).
Rhenium forms with tellurium compounds having
various compositions of tellurides (Re-Te. In the
system Re-Te are known following tellurides: Re2Te,
ReTe, Re3Te2, ReTe2, Re2Te5, Re2Te7. A synthesis
and investigation of rhenium tellurides was begun
comparatively of late. A formation of rhenium
tellurides in binary system Re-Te is shown in [80]. A
diagram of conditions in this system was made basing
the data of thermic analysis, and there are three
compounds in system Re-Te: ReTe2, Re2Te5, Re2Te7.
Most tellurized compound in system is ditelluride
ReTe2 (42.15% mass. of rhenium), the melting
temperature of which is 965 °C. Crystal lattice of the
rhenium ditelluride is rhombic and the parameters of
the lattice are following: a = 12.987 ± 0.007 Å; b =
13.055 ± 0.008 Å; c = 14.271 ± 0.008 Å.
The system Re-Te was investigated also by authors
[78] and according the data of thermic and X-ray
phase analysis was drawn a diagram of a condition of
this system. In difference with of the work [80] here
an interaction of rhenium and tellurium was
investigated in whole interval of concentration.
The authors [80] pointed out bad reproducibility of
experiments results and supposed that ReTe2 exists
within the limits of ReTe2.04 to ReTe2.47. Rhenium
ditelluride is a dark gray powder, continually resistant
to air and soluble in hot sulfuric acid
S. Furusev and A. Krekzsus [84] prepared rhenium
ditelluride by heating of weighted stoichiometric
amounts of components in evacuated and sealed
quartz ampoule during twenty days at the temperature
700 °C. After dispersing the samples were annealed in
the interval of temperatures 500-1100 °C and then
cooled in icy water. The authors made a supposition
that crystal lattice of rhenium ditelluride is rhombic.
Rhenium tellurides were also obtained by action of
Te and H2Te vapors in hydrogen flow to powdered Re
and ammonium perrhenate using technologies [6, 80].
As a result were obtained dark grey powders with
increased content of tellurium. Very bad
reproducibility of experiments is to be mentioned.
Samples containing 68.35% of Te are two-phased and
consist of ReTe2+Te. Despite of all efforts the authors
could not get samples exactly corresponding to ReTe2.
Thus, rhenium telluride are unstable even at
comparatively low temperatures, together with excess
of hydrogen, being deoxidant, causes bad
reproducibility of experiments as well as unsuccessful
efforts to obtain a compound with the composition
ReTe2. Abovementioned shows that using these
methods only solid samples or powders of rhenium
telluride can be obtained. Was investigated a structure
of crystals of Re2Te5 grown by gas transporting
reaction. The parameters of rhombic lattice Re2Te5
were close to ones found in [84] for the compound
ReTe2 what is an additional confirmation of possible
wide range of homogeneity between compounds
ReTe2 and Re2Te5, presence of which was shown in
[78, 80].
Thus, rhenium creates with tellurium a range of
compounds appropriating to different stages of
oxidation and most of these compounds can be
obtained by direct interaction of rhenium and
tellurium. For rhenium selenides are known following
compounds: Re2Se7 (heptaselenide), ReSe2
(diselenide), ReSe (monoselenide), Re3Se2 and Re2Se5.
Re2Se5 (rhenium pentaselenide) was obtained by
running H2Se through solution of KReO4 with
addition of potash for linking of some amount of
selenium discharging during the reaction. Rhenium
diselenide ReSe2 first was obtained by heating of
Re2Se in vacuum at 330 °C during 9 hours according
to reaction:
Re2Se7 2 ReSe2 + 3 Se.
Obolonchik Ch.A. and Mikhlina T.M. proposed a
method of obtaining rhenium diselenide by action of
dry H2Se to metallic rhenium or ammonium
perrhenate [79]. The optimal temperature of synthesis
in both cases is 700 °C.
The Electrochemical Deposition of Rhenium Chalcogenides from Different Electrolytes
193
Re + H2Se = ReSe2 + 2 H2.
2 NH4ReO4 + 7 H2Se = 2 ReSe2 + 2 NH3 + 8 H2O + 3
Se.
Rhenium diselenide is stable in hydrogen flow at
heating to 400 °C then, if the temperature continues to
rise, selenium detaches and at the temperature 900 °C
and more rhenium diselenide fully looses selenium
and stays pure metallic rhenium.
The formation of rhenium selenide ReSe2 is well
confirming by roentgenographic examination of
reaction products. In the work [85] was made
roentgenographic examination of part of system Re-Se
in an interval of concentrations 50-70% at. Se. To this
aim were synthesized and examined samples having
following composition: ReSe (50% at. Se), ReSe2
(66.6% at. Se), Re2Se5 (71.43% at. Se) and ReSe3
(75% at. Se). X-ray analysis of obtained samples
showed that in examined range of system exists only
one phase-ReSe2. ReSe and Re3Se2 are dark grey
roentgenoamorpfous powders. They do not dissolve in
water and organic solvents.
ReSe2 is a powder of black color, without smell
with density (according to pycnometric test) being
equaled 8.27 g/cm3. ReSe2 is entirely stable on air,
fully soluble while heated in hydrogen peroxide and in
mixed of nitric and sulfuric acids. In concentrated HCl
ReSe2 does not dissolve as in cold so when heated. In
nitric, sulfuric acids and in aqua regia it is partially
soluble when heated. The solution in mixed HNO3 and
H2O2 begins at cold and entirely runs under heating.
In 25% ammonia and ethyl alcohol rhenium diselenide
does not dissolve. ReSe2 is active catalyst for n-butane
dehydration to divinyl (the temperature of the reaction
~650 °C).
At present there are known several methods of
rhenium sulfides production. In system Re-S was
defined existence of rhenium sulfides with
composition: ReS, Re2S3, ReS2, Re2S5, ReS3 and
Re2S7 [41, 85]. Only ReS2 of all rhenium sulfides can
de produced by direct synthesis of components, other
compounds are to be produced by indirect methods.
Most stable compound of rhenium with sulfur is
ReS2. In the works rhenium disulfide was obtained by
direct interaction of elements in evacuated ampoules,
and in the study of C. Odent [82] by dissociation of
higher sulfides. It can be obtained by sulfidizing of
metallic rhenium [82] rhenium oxides (ReO2). ReS2 is
black powder, stable on air, has a density 7.506 g/cm3,
it does not dissolve in H2SO4, in HCl, as well in alkali.
The authors [49] supposed hexagonal one, MoS2 type.
Re2S5 (rhenium pentasulfide) is obtaining by long
pumping of hydrogen sulfide through acidic (1-4 HCl)
solution of perrenate [3] or in heated mixture of
rhenium perrhenate and sodium thiosulfate solutions.
As seems from abovementioned, using these
methods is possible to get rhenium chalcogenides in a
form of massive samples or powder [83, 84]. As
presently wide use in technique find rhenium
chalcogenides in a form of thin films there are needed
additional operations for conversion of
abovementioned samples to obtain thin films. In
connection with this an electrochemical method of
production thin films of rhenium chalcogenides on
conducting base takes on a distinctive importance.
The authors Sharipova N.S. and Songina O.A. [47]
investigated electrochemical behavior of selenium (VI)
with presence of rhenium (VII) at mercury dripping
electrode. Was defined that rhenium (VII) in this
condition shows one well defined wave in the range of
potentials -0.35-0.8 *n.k.e. At joint presence of
rhenium and selenium appears maximum at potential
-0.7 V, no observed before separately for rhenium or
for selenium, which carries catalytic character and
which can be used as calibrate graph for quantitative
definition of selenium.
We also have been studied semi-conducting
coatings of chalcogenides rhenium from different
electrolytes [66, 69-75, 81-83, 85-99].
For obtaining semi-conducting of Re-Se alloy we
investigated joint electrodepositing of rhenium and
selenium from alkaline [75] and sulfate [69, 70, 99]
electrolytes. To obtain Re-Se alloy from sulfate
The Electrochemical Deposition of Rhenium Chalcogenides from Different Electrolytes
194
electrolyte [69, 99] was used the electrolyte with
following composition (mole/L): 0.1-0.01 SeO2 +
0.01-0.1 NH4ReO4 + 2.0 H2SO4, a current density 10
mA/cm2, temperature 75 °C. For first time were
defined main regularities of co-deposition of rhenium,
selenium and rhenium by selenium from sulfate
electrolyte. Was found, that under definite conditions
of electrolyte the joint electrodeposition of rhenium
and selenium takes place. At first time was carried out
physics-chemical investigation of alloy forming in
system Re-Se when joint electrodeposing rhenium and
selenium from sulfate electrolyte. Basing on the
experimental data was proposed the interpretation of
cathodic process carrying out at various meanings of
cathodic potential. Basing on experimental data was
developed optimal composition of electrolyte and
electrolysis regime for obtaining quality
semi-conducting coatings of rhenium chalcogenides
from sulfate electrolyte [99]. For obtaining Re-Se
alloy from alkaline electrolyte we used the electrolyte
following composition (mole/L): 0.01-0.1 M
NH4ReO4 + 0.01-0.1 M SeO2 + 1-3 NaOH alkaline
electrolytes.
At first time using potentiostatic,
temperature-kinetics and voltammetric methods were
investigated kinetics and mechanism of separate and
joint electrodeposition of rhenium with chalcogenes
from alkaline electrolyte [75]. It was defined that the
mechanism of joint electrodeposition of rhenium with
selenium from alkaline electrolyte depends of
concentration of bivalent selenium obtained on
cathode, which optimizes reduction of rhenium with
forming of chemical compounds ReSe2. At a cathode
current density of 4 mA/cm2, using an electrolyte of
composition 0.05 M NH4ReO4 +0.05 M SeO2 + 1 M
NaOH, we obtained lustrous ReSe2 (54 wt% Re)
coatings. The formation of ReSe2 was confirmed by
XRD. At first time were investigated some
physics-chemical properties of thin coatings of Re-Se
alloys.Re-Te alloy we proposed and chloride-sulfate
[91, 97] electrolytes. For obtaining semi-conducting
alloy Re-Te in a form of thin films was found optimal
regime and electrolyte. For obtaining thin films of
rhenium chalcogenides in the work was proposed the
electrolyte and optimal regime for producing alloys.
To obtain thin films ReTe2 (rhenium ditelluride) is
necessary to carry out electrolyses at current density 2
mА/сm2, temperature 75 °C from electrolyte .
It was proposed an electrolyte and optimal regime
to get rhenium-tellurium thin films in chloride-borate
electrolyte [93, 94, 96] for obtaining alloys Re-Te.
Using potentiostatic, temperature-kinetic,
voltammetric methods were investigated kinetics and
mechanism of separate and co-electrodeposition of
rhenium and tellurium from chloride-borate
electrolyte. Was defined that a discharge of tellurium
complex on cathode runs through occurring of
intervening particles, arriving as a result of preceding
chemical reaction of tellurium complex dissociation.
At co-deposition of rhenium and tellurium from
chloride-borate electrolyte a main role plays a
chemical activity of tellurium connected with its
disposal to deep deoxidation and formation of Te2- at
the surface of a cathode. It changes a nature of
tellurium electrode and leads to co-electrodeposition
of rhenium and tellurium with formation of chemical
compound ReTe. It was found that finely crystalline,
glittering coatings with a composition of ReTe2 (42
wt% Re) and a thickness of up to 5 цш formed from
the electrolyte containing (M) 0.05 NH4ReO4 + 0.003
TeO2 + 3 HCl + 0.05 H3BO3 (electrolysis time 30 min,
current density 1.2 A/dm2, 0.25-0.20 V, s.c.e.).
According to X-ray phase analysis data, ReTe2
crystallized as an orthorhombic compound with unit
cell parameters a = 1.301 nm, b = 1.307 nm, and с =
1.428 nm [94].
Alloys of rhenium and sulfur are using as a
photosensitive material in semi-conducting technique
in a form of coatings. In works [72, 93-94] was widely
investigated co-electrodeposition of rhenium and
sulfur from sulfate and thiosulfate electrolyte [87].
Using the method of voltammetry was investigated a
The Electrochemical Deposition of Rhenium Chalcogenides from Different Electrolytes

process of electrodeposition of rhenium sulfide films
at platinum and titanium cathodes. Was proposed the
mechanism of this process including
electro-deoxidation of Re(VII) to Re(0) and chemical
interaction of Re with S. Was defined that to quality
and composition of films substantially influences a
concentration of main components in electrolyte, a
temperature, current density and acidity of electrolyte.
Using X-ray testing was proved that in
co-electrodeposition of Re and S at cathode is forming
chemical compound of rhenium disulfide ReS2. It was
defined that obtained coatings have p-tip conductivity.
The electrodeposition of thin films Re-S from aqueous
solutions containing ammonium perrhenate,
thiocarbamide and sulfuric acid was made in the work
[72]. The electrolytic alloys Re-S were obtained from
the electrolyte of the following composition: 0.1 ×
103-2.0 ×103-MNH4ReO4; 1 × 10-3-3 × 10-3
M(NH2)2CS; 0.5 × 10-3-1.23 × 10-3 MH2SO4; pH =
1-1.5, current density being 25-45 mA/sm2.
At first time was physical-chemical investigation of
alloy formation in Re-S system and was defined that
co-electrodeposition of rhenium and sulfur depends of
adsorption of colloidal sulfur on cathode, and as
rhenium so sulfur deposit by depolarization which
affirms the formation of chemical compound ReS2.
The rhenium alloys have found wide application in
radio technique, electronics, semi-conducting industry
and other fields of modern technique. In this
connection undoubted practical and theoretical interest
has the electrochemical deposition of rhenium.
Also in the review indicates that the rhenium alloys
are widely used in electronics, electrical engineering,
electronics and semiconductor industry and other
areas of modern technology. Thus, from
abovementioned review is clear that acidic and
alkaline solutions are good electrolytes for the
production of coatings of rhenium alloys.
Therefore, a detailed study of the process of
co-electrodeposition of rhenium with chalcogenides
of alkaline and acidic electrolytes has practical and
theoretical interest.

... Such hydrogen evolution can last for several tens of seconds but still it is determined not by rhenium dissolution in acid deposition electrolyte, but by hydrogen desorption from the metal. This fact indicates that the electrolytic rhenium is oversaturated with hydrogen in compliance with the data [2][3][4]. The volume of the dissolved hydrogen exceeds by many times the volume of rhenium, and the rate of hydrogen diffusion in rhenium is obviously quite high. ...

The urgent need of the synthesis of ammonia (NH3) due to its utility in the agriculture and fine chemical industries attributed the researchers to design new technologies for nitrogen (N2) fixation. To date, NH3 has mostly been produced by the Haber-Bosch process in industry. Although, the proficiency of this process, that is, reduction of nitrogen carried out using high-elevated temperature and pressure besides of emission of CO2 gases. Hence, numerous studies had implanted to perform the nitrogen fixation process through mild conditions at room temperature. The exploration of metal chalcogenide-based nanomaterials had experienced tremendous efforts in the scientific community, especially in the field of photocatalysis because these materials had proved to possess a narrow band gap and strong absorption of visible light. In addition, the development in the biological method of ammonia formation using FeMo protein comprising of iron-sulfur clusters is also attracted greatest interest. Researches targeting the modification of FeMo protein and Fe protein only had been developed for investigation of light-driven the formation of ammonia from nitrogen. Therefore, the focus of this chapter is the survey of state-of-art engineering of efficient photocatalysts based on chalcogenide nanostructured for N2 fixation toward NH3 synthesis under visible light irradiation, in aqueous media, under ambient pressure and room temperature. Subsequently, the future prospects at the forefront of this research platform have been illustrated.

In this chapter, the synthesis strategies of chalcogenide-based nanomaterials in order to obtain desired properties for photocatalytic application are reviewed. The different dimensional structures of nanomaterials as well as the number of involved elements, from binary to multinary compound system of chalcogenide offer complexities in designing suitable fabrication method. Scientists have developed a variety of methods for the preparation of nanostructured chalcogenide compound, including the solvothermal and hydrothermal, hot/noninjection method, solid synthesis method, thermal decomposition, template-directed synthesis among others. These methods can be classified as direct and indirect synthesis methods. Stoichiometry tuning and structure modification in relation to desired photocatalytic properties are highly dependent on the preparation strategies. The novel cutting-edge technology and future development of chalcogenide nanomaterials synthesis technique are also discussed.

Nanomaterials are composed of several atoms or molecules, which may be of various sizes and morphologies. Manmade nanomaterials are specially produced to take advantage of the unique properties of nanoscale. There are many metal chalcogenides with different structures and compositions such as CdSe, InAs, CdS, GaN, InGeAs, CdTe, PbS, PbSe, ZnS, Na2S, CaTe, Ti2S, and Cu2Se. The diversity of metal chalcogenides is related to the orbit of transition metals. In this chapter, new studies using chalcogenide compounds as photocatalysts were explained under the subtopics of metal chalcogenides and their properties, semiconductive nanostructures, nanomaterial production technique, chemical synthesis methods, and metal chalcogenides as photocatalysts. Novel applications of metal chalcogenide-based materials like water splitters, organic pollutant degraders, self-cleaning agents chalcogenide glasses and thermoelectric materials are explained in detail under the relevant headings. Future prospects of chalcogenides are also evaluated from a different perspective.

There has been investigated the joint electrodeposition of rhenium with tellur from chlorides electrolyte, by measuring the cycling volt-ampere curves there has been determined the field of potentials, at the presence of which the joint electrodeposition of rhenium with sulphur takes place. It has been shown, that the joint deposition of rhenium with tellur goes with a certain depolarization, besides, the depolarization is caused by the energy emanating along formation of ReTe2 compounds. There was studied the influence of current density, temperature and acidity on the composition and quality of cathode sediments. It was established, that with the rise of current density and the temperature of electrolyte the concentration of rhenium in the alloy increases.

The investigation of electrodeposition of rhenium in alkaline and acidic electrolytes was carried out, polarization curves were obtained by electrochemically and cyclically potentiodynamic methods. By the investigation of rhenium concentration, sulphuric acid, alkali, ammonium sulphate, temperature and acidity of solution, it was found that reaming velocity was an optimal regime and electrolyte composition for an obtaining of high quality rhenium deposits from an alkaline electrolyte and acidic electrolyte. It was defined that the process of electrodeposition of rhenium in alkaline electrolyte is accompanied by chemical polarization and the electrodeposition of rhenium in acidic electrolyte goes gradually with the formation of intermediate films of sediments.

There have been investigated the kinetics and mechanism of the cathode electrodeposition of thin coverings Re-Se from the sulphate electrolyte, containing NH4ReO4, SeO2 and H2SO4. On the base of X-ray phase analysis and by the method of cyclic avometry there have been determined the content of obtained coverings, electrosettled at the various concentrations of components in electrolyte. The co-deposition process was shown to be attended by depolarization, which is due to the energy release upon the formation of the alloy.

Electrophysical properties of the two-layer film systems based on Ge and Cr as two-layer film a-Ge/Cr/S or over Ge/Cr/S are studied. It is found that at a limited thickness of dGe 􀀣 10-15 nm there is an inversion of sign value of 􀀧R/R 􀀠 [R(Ge/Cr) – R(Cr)]/R(Cr) from 􀀧R/R < 0 (for dGe < 10-15 nm) to 􀀧R/R > 0 (for dGe > 10-15 nm). This result is explained by the formation of excitons of Wannier-Mott type that leads to a decrease in the concentration of free-carriers and, as a result of it, to the increase in the value of 􀀧R/R.

The kinetics and mechanism of cathode electrodeposition of thin Re-Te films from a chloride-borate electrolyte containing NH4ReO4, TeO2, HCl, and H3BO3 were studied. The region of potentials in which rhenium is electrodeposited together with tellurium was determined by cyclic voltammetry. The combined electrodeposition of rhenium and tellurium occurred with minor depolarization due to the energy liberated during the formation of the Re-Te alloy.

The aim of this work was to obtain Ni - Re binary alloy by a simple method of electrodeposition. Nickel - rhenium alloys have been deposited from nickel sulfamate and ammonium perrhenate electrolyte with citrate-anion additives. The effects of bath temperature, current density, bath composition and influence of magnetic field were studied. The impacts of these parameters on hydrogen evolution process for obtained Ni - Re alloys were examined. The deposited layers were determined by optical and scanning electron microscopy (SEM), X-ray diffraction (XRD) and X-ray fluorescence (XRF).

The electrochemical behavior of electrodeposited Ni-Co-Re triple alloy is investigated in an alkaline medium and the kinetic parameters for the hydrogen evolution reaction are determined. The results are compared with those for electrodeposited Ni and Ni-Co alloy. The hydrogen evolution reaction occurs at a lower overpotential in the case of the triple alloy, which appears thereby as a promising electrocatalytic material for a negative electrode in an alkaline water electrolysis.

The photophysical and electrochemical properties of a novel metallopolymer containing [Re(bpy)(CO)3]+ moieties coordinated to a poly(4-vinylpyridine) polymer chain are reported. Significantly, the release of the metal complexes can be triggered by oxidation or reduction of the rhenium complex. Solvent rapidly binds to the vacant coordination site to give a luminescent product. The redox and photophysical properties of the parent metallopolymer and the released solvated complex are compared. Along with photoemission, the metallopolymer generates significant electrogenerated chemiluminescence upon reduction in the presence of benzoyl peroxide as coreactant.
