Abstract

ABSTRACT: Bismuth vanadate (BiVO4 ) was synthesized via ethanol-assisted solvothermal method performing at heating temperature of 200°C for 2–6 h. Characteristics of BiVO4 were investigated by X-ray diffraction, field emission-scanning microscopy and Brunauer, Emmett and Teller technique. Single monoclinic phase with T-shape like particles was obtained and average crystalline sizes as well as surface area were improved by a prolonged reaction time. Electron transitions in the structure were described by diffuse reflectance of the BiVO4 . Moreover, X-ray absorption spectra at vanadium K-edge were presented in more information of chemical structure of vanadium's oxidation state and bond distance between vanadium and oxygen.
