    ABSTRACT: NiTiO3/NiFe2O4 nanocomposites were prepared via a simple sol-gel auto-combustion route using onion extract as a novel fuel and green capping agent. The present work focused on the synthesis and characterization of NiTiO3/NiFe2O4 nanocomposites for the first time. First, a sol of NiFe2O4 was obtained, from metal nitrates and onion extract as reductant. Second, a sol of titanat was prepared by mixing of tetra-n-butyl orthotitanate, diethanolamin and ethanol. Then obtained sol was added to the NiFe2O4 sol. The molar ratio of Ti to Ni had significant effect on morphology, magnetic properties, purity and phase of nanocomposites. Nanocomposites were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), cyclic voltammetry (CV) and vibrating sample magnetometer (VSM). The magnetic properties of the samples were also investigated using an alternating gradient force magnetometer where the optimum condition was performed in the molar ratio Ti/Ni 1:1. The photocatalytic activity of the synthesized products has been compared with the photodegradation activity of methyl orange (MO).

    ABSTRACT: In this paper, we report a novel electrochemical sensor for the sensitive detection of Cu(II) ions based on Tl2O3 nanostructures supported on multi-walled carbon nanotube—pencil graphite electrode. Firstly we reported the synthesis and characterization of Tl2O3 NSs via sonochemical method. The as-synthesized nanostructures were characterized by scanning electron microscopy, X-ray powder diffraction, energy dispersive X-ray spectroscopy and transmission electron microscopy. According to our knowledge, it was first time that ethylenediamine and propylendiamine were used as pH controller agent in synthesis of Tl2O3 nanostructures. Finally, a pencil graphite electrode was decorated using Tl2O3 NSs and MWCNT to provide an electrochemical device for Cu2+ ions sensing. Using this modified electrode, three oxidation states of copper ions were observed. This device showed agreeable responses to trace amounts of Cu2+ in phosphate buffer solutions in which the limit of detection was found to be 4.63 nmol/L for Cu2+.

    ABSTRACT: Barium molybdate (BaMoO4) micro- and nano-crystals were synthesized by the coprecipitation method. Utilizing the water as the solvent provides octahedron-like nanostructures. These nano-crystals were structurally characterized by X-ray diffraction, energy dispersive X-ray micro-analysis, Fourier transform infrared spectra. The size and shape were observed by scanning electron microscopy. The optical properties were studies by ultraviolet–visible diffuse reflectance spectroscopy and photoluminescence measurements at room temperature. The effects of temperature, solvent, surfactant and barium source were considered to obtain a controlled shape. It is found that the morphology, particle size and phase of the final products are extremely affected by these parameters.

    ABSTRACT: In the present study, hydroxyl functionalized nickel(II) Schiff-base; [Ni((OH)2-salophen)] [(OH)2-salophen]=(N,Ń-bis(4-hydroxysalicylidene)phenylene-1,2-diamine); has been covalently anchored on modified multi-wall carbon nanotubes (MWNTs); [Ni((OH)2-salophen)]@MWNTs]. The new modified MWNTs have been characterized by transmission electron microscopy (TEM), thermal analysis, UV-Vis, Diffuse reflectance (DRS), FT-IR spectroscopy and elemental analysis. The results suggest that the symmetrical Schiff-base is a bivalent anion with tetradentate N2O2 donors derived from the phenolic oxygen and azomethine nitrogen. Multi-wall carbon nanotubes which covalently anchored nickel(II) complex catalyze the oxidation of cyclohexene with molecular oxygen.

    ABSTRACT: In this work, we have successfully prepared flower-like strontium molybdate nanostructures via coprecipitation approach by utilizing Sr(Sal)2 (Sal = salicylidene) and ammonium hepta molybdate as starting materials in water as solvent. Phases, morphologies and optical properties were analyzed by Fourier transform Infrared spectra, X-ray diffraction, energy dispersive X-ray microanalysis, ultraviolet–visible spectroscopy, photoluminescence spectroscopy and scanning electron microscopy. To obtain optimum conditions, we considered the effects of temperature, solvent, surfactant and strontium source. It was established that morphology, particle size and phase of the final products could be extremely affected via these parameters. It was revealed that utilizing of water as solvent provided flower-like nanostructures.

    ABSTRACT: Barium haxaferrite (BaFe12O19) nanostructures were synthesized by a coprecipitation technique from metal nitrates and palm oil without adding external surfactant, capping agent or template. The effects of processing parameters such as the dosage of palm oil and calcination temperature on the crystalline phase formation and magnetic properties were systematically investigated. The biosynthesized barium haxaferrite nanostructures were characterized by using X-ray diffraction (XRD), scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FT-IR). The XRD patterns revealed that high calcination temperature and palm oil dosage are beneficial for the formation of barium haxaferrite nanostructures. Products with high coercive force of 5000 Oe and saturation magnetization of 28 emu/g were obtained when the palm oil/nitrates molar ratio and calcination temperature were 26/1 and 900 °C, respectively.

    ABSTRACT: Using solid organic molecular precursor "[bis(salicylaldehyde) ethylenediiminelead(II)]; [Pb(salen)]" and "[bis(salicylaldehyde) phenylenediiminelead(II)]; [Pb(salophen)]" as precursors, for a surfactant-free method to synthesis PbTe nanostructures were proposed. The effect of time and temperature on the morphology of the products was investigated. Results showed that the main factor on formation of different morphologies of PbTe nanostructures was temperature, but by increasing the time the nanostructures grew together. It was found that the as-obtained PbTe nanostructures exhibit a strong PL peak at room temperature.

    ABSTRACT: PbSe rod-shape nanostructures have been successfully synthesized by a facile hydrothermal route using PEG4000 as additive agent. The as-obtained products were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDX). The effect of experimental parameters on the formation of different morphologies and possible mechanism were investigated. Effects of temperature, reaction time and reductant agent on the morphology, the particle sizes and the phase of the final products have been investigated. It was found that the phase and morphology of the products could be greatly influenced by these parameters. The synthesis procedure is simple and uses less toxic reagents than the previously reported methods. The studies on the optical properties of PbSe nanostructures were carried out by UV–vis absorption spectrum and photoluminescence spectrum.

    ABSTRACT: A facile route for large-scale synthesis of zinc telluride nanostructures has been achieved by a hydrothermal method. Scanning electron microscopy images showed many nanorods stuck together in the middle, composing a typical nanorod bundle. These nanorods consisted of widths in the range ~37~nm and lengths up to several micrometres. Based on a series of contrast experiments under different reaction conditions, some probable effective factors such as capping agents, reductant sorts, time and temperature were discussed.
