Research Progress on Improving the Carrier Separation Effi ciency of Bismuth Vanadate P hotocatalysts

钒酸铋(BiVO_(4))因具有合适的物化性质,如较强的可见光吸收能力、性质稳定、无毒等,让光催化研究者对其产生了极大兴趣,但钒酸铋在光催化过程中光载流子易复合,因此致使其光催化效率低。为了解决钒酸铋光载流子易复合这一难题,光催化研究者采取了多种策略。本文总结了现如今提高钒酸铋光载流子分离率的策略以及效果,综合分析了钒酸铋的发展前景。

Bismuth vanadate(BiVO_(4))has attracted great interest in photocatalysis researchers due to its suitable physicochemical properties,such as strong visible light absorption,stable performance,and non-toxicity.But,the photocarriers of bismuth vanadate are easy to recombine,resulting in low catalytic efficiency.In order to solve the problem of low carrier separation efficiency of bismuth vanadate,photocatalysis researchers have adopted different strategies.This paper summarizes the current strategies to improve the carrier separation efficiency of bismuth vanadate and their effects.Finally,the development prospect of bismuth vanadate is comprehensively analyzed.
