Vanadium pentoxide (V2O5) is one of the fundamental materials applied in productions batteries, vanadium-aluminium alloys, biomedicine, catalysis, etc. High purity V2O5 can be prepared from an intermediate product, namely ammonium polyvanadate (APV), using roasting after a drying process. In this paper, microwave heating was used as alternative option for APV, which has advantages including sel...

The use of different vanadium sources in the synthesis multi-metal MoVTeNb oxide catalysts has been investigated for their effect on physicochemical properties catalysts. Metal oxides were synthesized by slurry method assisted with a microwave irradiation. Vanadium pentoxide (V2O5), vanadyl sulphate (VOSO4) and ammonium metavanadate (NH4VO3) used as sources, respectively. X-ray diffraction (XRD...

We studied the effect of ethanol vapour on parameters semiconductor-metal transition in a polycrystalline vanadium dioxide powder stable monoclinic phase a-VO2. It was synthesised by reducing pentoxide with oxalic acid while heated air. The DC electrical resistance samples between room temperature and 100оС tubular heater, microcompressor-generated air stream saturated ethyl alcohol vapour. fou...

Heavy metals are the source of substantial environmental and health problems. Vanadium pentaoxide (V2O5) is an environmental and industrial pollutant that affects body physiology via the food, drinking water and through the air. Toxicological study of V2O5, following acute (1day) and subacute (7, 14, 21 days) exposure, alter behaviour and serum biochemistry in Wistar rats in terms of significan...
