Microwave-assisted synthesis bismuth vanadate (BiVO<inf>4</inf>) powder
Bismuth vanadate (BiVO 4 ) powder was synthesized by the microwave method. Bismuth nitrate pentahydrate (Bi(NO 3 ) 3 .5H 2 O) and ammonium vanadate (NH 4 VO 3 ) 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 a...

| Summary: | Bismuth vanadate (BiVO 4 ) powder was synthesized by the microwave method. Bismuth nitrate pentahydrate (Bi(NO 3 ) 3 .5H 2 O) and ammonium vanadate (NH 4 VO 3 ) 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 (NH 4 OH). 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 BiVO 4 powder was identified by X-ray diffraction (XRD). The morphology and chemical composition of BiVO 4 powder were investigated by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDXS), respectively. The surface area of BiVO 4 powder was determined by Brunauer-Emmett-Teller analysis (BET). © 2013 Copyright Taylor and Francis Group, LLC. |
