Bismuth oxychloride nano-materials have attracted extensive attention in the field of photocatalysis because of its special layered structure,high stability and good photocatalytic activity,which can efficiently degrade organic pollutants in water.The construction and regulation of heterogeneous interface is beneficial to improve its shortcomings such as narrow light response range and easy recombination of carriers,so as to improve the utilization rate of sunlight and its photocatalytic activity.In this paper,the structural characteristics of BiOCl photocatalyst are introduced.The characteristics and potential applications of eight widely studied BiOCl-based heterojunctions in photocatalytic field are summarized,and the research direction of BiOCl photocatalyst is prospected.This review aims to provide a useful reference for researchers who are currently focusing on exploring new BiOCl-based photocatalysts.
