Recent Progress in Bismuth Vanadate-Based Photocatalysts for Photodegradation Applications

Bismuth vanadate (BiVO4), a well-known semiconductor photocatalyst with various advantages, has shown great potential in addressing energy and environmental issues. However, its inherent drawbacks restrict the photocatalytic performance of pure BiVO4. In the past few years, many efforts have been devoted to improving the catalytic activity of BiVO4 and revealing the degradation mechanism in depth. In this review, we summarized the recent progress on BiVO4 in the field of photocatalytic degradation, including the strategies which enhance light absorption ability and suppress the recombination of charge carriers of BiVO4, as well as the related degradation mechanism. Finally, future prospects and challenges are summarized, which may provide new guidelines for designing more effective BiVO4-based photocatalysts for the degradation of persistent organic pollutants.
