Results of the investigation of the reactions of GaCl3, InCl3 and InI3 with LiNH2 under solvothermal conditions in benzene, which lead to metal nitrides, are reported. GaN is obtained as a cubic phase or as a mixture of cubic and hexagonal phases, depending on temperature. The effect of the addition of surfactants on the formation of GaN was explored. InN products were always contaminated with ...

The ternary I-III-VI(2) semiconductor of CuInSe(2) nanoparticles with controllable size was synthesized via a simple solvothermal method by the reaction of elemental selenium powder and CuCl as well as InCl(3) directly in the presence of anhydrous ethylenediamine as solvent. X-ray diffraction patterns and scanning electron microscopy characterization confirmed that CuInSe(2) nanoparticles with ...

η-Mn3N2 is produced using solvothermal reactions between MnCl2 and LiNH2 in benzene. At 350 °C nanocapsule structures are obtained, whereas at higher temperatures samples consisted of isotropic nanoparticulates. In aqueous KOH solution capacitances of up to 300 F g (2 mV s, potential window 0.3 to -0.6 V vs Hg/HgO), but capacitance fell to relatively low values on cycling. In lithium cells a re...

LiFePO4 nanocrystals were synthesized at a very low temperature of 170°C using carbon nanoparticles by a solvothermal process in a polyol medium, namely diethylene glycol without any heat treatment as a post procedure. The powder X-ray diffraction pattern of the LiFePO4 was indexed well to a pure orthorhombic system of olivine structure (space group: Pnma) with no undesirable impurities. The Li...

Binary skutterudite CoSb(3) nanoparticles were synthesized by solvothermal method. The nanostructuring of CoSb(3) material was achieved by the inclusion of various kinds of additives. X-ray diffraction examination indicated the formation of the cubic phase of CoSb(3). Structural analysis by transmission electron microscopy analysis further confirmed the formation of crystalline CoSb(3) nanopart...

Mn-doped zinc oxide nanoparticles were prepared by using the microwave solvothermal synthesis (MSS) technique. The nanoparticles were produced from a solution of zinc acetate dihydrate and manganese(II) acetate tetrahydrate using ethylene glycol as solvent. The content of Mn(2+) in Zn1- x Mn x O ranged from 1 to 25 mol %. The following properties of the nanostructures were investigated: skeleto...

CeO2-MO x (M = Cu, Co, Ni) composite yolk-shell nanospheres with uniform size were fabricated by a general wet-chemical approach. It involved a non-equilibrium heat-treatment of Ce coordination polymer colloidal spheres (Ce-CPCSs) with a proper heating rate to produce CeO2 yolk-shell nanospheres, followed by a solvothermal treatment of as-synthesized CeO2 with M(CH3COO)2 in ethanol solution. Du...

Mesoporous TiO2 microspheres assembled from TiO2 nanoparticles with specific surface areas as high as 150 m(2) g(-1) were synthesized via a facile one-step solvothermal reaction of titanium isopropoxide and anhydrous acetone. Aldol condensation of acetone gradually releases structural H2O, which hydrolyzes and condenses titanium isopropoxide, forming TiO2 nanocrystals. Simultaneous growth and a...

Pd, Cu, and Zn trimetallic metal-organic framework electrocatalysts (PCZs) based on benzene-1,3,5-tricarboxylic were synthesized using a simple solvothermal synthesis. The as-synthesized PCZ catalysts exhibited as much 95% faradaic efficiency towards CO, with high current density, low onset potential, excellent long-term stability during the electrocatalytic reduction of CO2.

−Metal organic frameworks (MOFs) are porous crystalline materials of one-, two-, or three-dimensional networks constructed from metal ions/clusters and multidentate organic linkers via coordination bonding, which are emerging as an important group of materials for energy storage, CO2 adsorption, alkane/alkene separation, and catalysis. To introduce newcomers in chemical engineering discipline t...
