Abstract：Photocatalytic technology has broad application prospects in the fields of environment protection and energy production.Bismuth oxychloride(BiOCl),as a potential photocatalyst,has garnered signifi-cant attention.However,the performance of BiOCl is limited by several factors,such as weak visible light response,severe recombination of photogenerated charge carriers,and a lack of active catalytic sites.To overcome these drawbacks,various material modification strategies have been employed,including the construction of heterostructures,elemental doping,and defect engineering.This review focuses on the roles of these three strategies,including heterostructure construction,elemental doping,and defect engi-neering,in enhancing the photocatalytic performance of BiOCl,as well as the research progress of BiOCl-based photocatalysts in practical applications.In summary,although BiOCl-based photocatalysts have demonstrated enormous potential for pollutant degradation,carbon dioxide reduction,hydrogen produc-tion,and nitrogen oxide removal,further optimization and innovation are still needed to promote their in-dustrial applications.
