Advances in the research of nanoparticles (NPs) with controlled charge and size are driven by their potential application in the development of novel technologies and innovative therapeutics. This work reports the synthesis, characterization, and comprehensive biological evaluation of AgNPs functionalized by N,N,N-trimethyl-(11-mercaptoundecyl) amm...
Article
Full-text available
Metal oxide-organic hybrid semiconductors exhibit specific properties depending not only on their composition but also on the synthesis procedure, and particularly on the functionalization method, determining the interaction between the two components. Surface adsorption is the most common way to prepare organic-modified metal oxides. Here a simple...

In this paper, we describe the role of anatase and rutile crystal phases on diphenyl sulphide (Ph2S) catalytic and photocatalytic oxidation. The highly selective and efficient synthesis of diphenyl sulfoxide (Ph2SO) and diphenyl sulfone (Ph2SO2) at titanium dioxide was demonstrated. Ph2S oxidation in the presence of hydrogen peroxide at anatase-TiO...
Article
The diffuse reflectance spectroelectrochemistry (SE-DRS) and reversed double-beam photoacoustic spectroscopy (RDB-PAS) provide unique, complementary information on the density of electronic states (DOS) in the vicinity of the conduction band bottom. The measurements are performed under quite different conditions, representing the solid/liquid and s...
Article
We developed low-temperature (up to 200 °C) synthesis of TiO2 nanocomposites, which allows precise tuning of the anatase/rutile ratio. The materials were synthesized hydrothermally from strongly acidic solutions of Ti(III) precursors and hydrogen peroxide. Two series of materials (A and B series) have been synthesized; the A series is characterized...
Chapter
Thermodynamics and kinetics of primary photophysical and photochemical processes govern the overall photoactivity of photocatalytic and photoelectrocatalytic systems. A proper determination of redox potentials, Fermi levels, quasi-Fermi levels, distribution of electronic states and surface traps, as well as lifetimes of photogenerated charge carrie...
Article
Full-text available
Resistance of microorganisms to antibiotics has led to research on various therapeutic strategies with different mechanisms of action, including photodynamic inactivation (PDI). In this work, we evaluated a cationic, neutral, and anionic meso-tetraphenylporphyrin derivative's ability to inactivate the Gram-negative and Gram-positive bacteria in a p...
Article
We have synthesized and characterized a series of TiO2(B)/anatase photocatalysts in the form of nano-belts. Spectroelectrochemical measurements (SE-DRS) revealed the staggered-type of the band alignment for anatase and TiO2(B) composites, with higher potentials of band edges for anatase. The photoactivity of the materials and photocurrent generatio...
Article
A visible light responsive heterojunction system composed of Fe2O3 nanorods (NF), reduced graphene oxide (rGO) and double oxide perovskites (LaSrFe2–nConO6, n = 1 (LSFC) and 0 (LSFF)) was rationally designed for an effective photoelectrochemical water splitting. The photoelectrodes were characterized in terms of structure, surface, physicochemical...
Article
Full-text available
Hydrogen production by photocatalytic water splitting is one of the most promising sustainable routes to store solar energy in the form of chemical bonds. To obtain significant H2 evolution rates (HERs) a variety of defective TiO2 catalysts were synthesized by means of procedures generally requiring highly energy-consuming treatments, e.g. hydrogen...
Article
Synthetic procedures, including doping, sintering and surface coating, can noticeably affect the physicochemical properties of semiconductors. Introduced changes very often translate into photocatalytic and photoelectrochemical activity alterations. However, in this work we have focused on more subtle treatments, which result in lack of changes obs...
Article
Full-text available
Highly-active, surface-modified anatase TiO2 nanoparticles were successfully synthesized and characterized. The morphological and optical properties of the obtained (metallo) porphyrin@qTiO2 materials were evaluated using absorption and fluorescence spectroscopy, scanning electron microscopy (SEM) imaging, and dynamic light scattering (DLS). These...
Article
The goal of the work is to verify which properties of TiO2-based materials, influenced by small amounts of Fe, Co, Ga, Bi, W, Mo, V and Ni species used as modifiers, play the predominant role in changing the photoactivity of TiO2. Two groups of materials were studied: TiO2 synthesized in the presence of nanocrystalline metal oxide and dissolved met...

Tai­lored crys­tals of anatase TiO2 have been syn­the­sized us­ing a hy­drother­mal method with hy­dro­flu­o­ric acid and sodium flu­o­ride as cap­ping agents. Ti­ta­nium diox­ide in the form of sheets, tetrag­o­nal trun­cated bipyra­mids, cuboids and belts of­fer dif­fer­ent ex­posed facets: {001}, {001}/ { 101}, {001}/ { 100} and {100}, re­spec­t...

In order to solve the shortage of sustainable energy and the related concern about combustion of fossil fuels, converting the most abundant solar energy into chemical fuels becomes one of the most promising choices to provide the everlasting and environmentally friendly energy vector along with the minimum impact to environment. Among the methods o...

In this study, the protocol of a single-step l-cysteine functionalized silver nanoparticle synthesis was described. Particle size distribution was determined. The crystallinity and chemical properties were investigated using XRD, HR-TEM, and XPS methods. Acute toxicity and irritant properties of obtained nanoparticles were studied using mice and ra...
Chapter
Although production of solar fuels from water or carbon dioxide seems still too expensive to compete with fossil fuels, application of photocatalysis for synthesis of valuable organic chemicals may appear an interesting approach. The use of a photocatalyst and light as the energy source can be considered as a green, sustainable alternative for othe...
Article
The information on the electronic structure of nano- and microstructured semiconductors is crucial for their applications in photovoltaics, optoelectronics and photocatalysis. The distribution of intra-bandgap electronic states is one of the most relevant parameters which may be tuned in order to provide desired properties of a photoactive material...
Article
Anatase-brookite TiO2 photocatalysts were prepared by the sol-gel process controlled within reverse micelles and processing by pressurized hot solvents − water/methanol/water (TiO2(M)) and water/ethanol/water (TiO2(E)), as an unconventional alternative to common calcination. The main goal of this work was to prepare anatase-brookite mixtures by pro...
Article
Utilization of visible light by photosensitization of semiconductor photocatalysts via surface attachment of small colorless organic pollutants (COP) is an effective way to stimulate their photocatalytic degradation. Herein, by means of the spectroscopic, photoelectrochemical, spectroelectrochemical and photocatalytic studies combined with the DFT+...

Full-text available
Rutile form of titanium dioxide (r-TiO2) usually shows a lower photocatalytic activity when compared to anatase-TiO2 (a-TiO2). Nevertheless, there are numerous examples of sometimes unexpectedly high activity of r-TiO2. This material may appear particularly useful when a non-complete and selective photocatalytic oxidation of organic substrates is r...
Article
A group of selected hexafluorometallates ([AlF6]3–, [TiF6]2–, [ZrF6]2–, [SiF6]2–) has been adsorbed at titanium dioxide. Such modification influenced electronic and chemical properties of TiO2, as well as its photoactivity. The modification with [TiF6]2– inhibited the efficiency of OH• production, but enhanced generation of photocurrent and singlet...
