Recent advances in the high performance BiOX (X=Cl, Br, I) based photo-catalysts

Abstract

Bismuth-based semiconductor of BiOX (X=Cl, Br, I) has proved to be a new promising photocatalytic material due to its unique layered crystal structure and suitable band gaps, which exhibits superior photocatalytic performance and high stability. In this review, some key scientific topics in terms of photocatalysis of BiOX (X=Cl, Br, I) were firstly addressed, then the effective modification methods were comprehensively summarized, including microstructure adjustment, heterojunction construction, noble-metal deposition, doping, surface sensitization, etc. In addition, the research progress in catalyst immobilization by loading nano-structured BiOX (X=Cl, Br, I) onto appropriate carriers were also reviewed. Generally, this review presents the most recent advances of high performance of the BiOX (X=Cl, Br, I) based photocatalysts in depth and also prospects the research trend of the BiOX (X=Cl, Br, I) catalyst.
