Abstract

Abstract: The development of single phase photocatalyst is expected to realize clean energy and pollution treatment. Herein, we reported a novel Tremella-like Bi2 WO6 catalyst which was obtained by facile hydrothermal technique. The formation of Tremella-like Bi2 WO6 strongly depended on introduction of Bi2 O3 . Based on the Kirkendall effect, Bi2 O3 induced Bi(NO3 )3 ·5H2 O to form biscuit-like Bi6 O6 (OH)3 (NO3 )3 ·3H2 O particles which provided templates and reacted simultaneously with WO4 2− to synthesize Tremella-like Bi2 WO6 . The Tremella-like Bi2 WO6 exhibited remarkable visible-light catalytic performance. The degradation rate of RhB dye reached 100% with 10 min, the reduction rate of CO2 was 5.5 times higher than pure Bi2 WO6 . Moreover, the Tremella-like Bi2 WO6 catalyst displayed excellent stability during the recycle experiments. The high catalytic activity makes single phase Bi2 WO6 catalyst great potential in environmental protection field.
