Abstract: Bismuth vanadate (BiVO4) powder was synthesized by the microwave method. Bismuth nitrate pentahydrate (Bi(NO3)3.5H2O) and ammonium vanadate (NH4VO3) were used as the starting precursors with the mole ratio of 1:1. The mixed solution was stirred and adjusted the pH of solution to 7 with ammonium hydroxide (NH4OH). The yellow final solution was treated in the microwave with an irradiation power at 600, 700 and 800 Watt for 2, 4 and 6 min, respectively. The phase of BiVO4powder was identified by X-ray diffraction (XRD). The morphology and chemical composition of BiVO4powder were investigated by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDXS), respectively. The surface area of BiVO4powder was determined by Brunauer-Emmett-Teller analysis (BET). © 2013 Copyright Taylor and Francis Group, LLC.
