Abstract

Bi2WO6 photocatalyst powder was synthesized by molten salt method using precipitate from mixed Bi(NO3)3 and Na2WO4 aqueous solutions with and without addition of ammonia, commercial Bi(NO3)3×5H2O and Na2WO4×2H2O as precursors, respectively. The effects of precursors on the phase composition, morphology and degradation of RhB under visible light were examined. The results indicated that pure flake-like Bi2WO6 powder could be prepared from two precursors: precipitate from mixed Bi(NO3)3 and Na2WO4 aqueous solutions with addition of ammonia solution, and commercial Bi(NO3)3×5H2O+Na2WO4×2H2O. Bi2WO6 powder originated from the former precursor performed better on the photocatalytic degradation of RhB, which could degrade 0.01 mmol/L RhB almost completely (99%) under visible light irradiation within 60 min.

Key words： Bi2WO6; molten salt method; precursor; photocatalysi; RhB
