Preparation of Bismuth Oxyhalide-Based Modified Photocatalysts and Application Progress in Environment Remediation
As a novel photocatalyst,bismuth oxyhalide(BiOX,X=Cl,Br,I),has attracted extensive attention from environmental researchers due to its unique layered structure and suitable band gap.However,the lack of rapid recombination of photoelectron-hole pairs limits its further applications.Modification of BiOX to improve its photocatalytic activity is a key strategy to solve the above issue.In this review,the research progress in photocatalytic technology of modified bismuth oxyhalide in recent years is summarized,and the synthesis strategies of bismuth-rich BiOX,doping,defect,heterojunction,morphology regulation and other modified BiOX are described in detail.Moreover,the development status of modified BiOX in the field of environmental remediation is reviewed.Finally,the development trend and challenges of modified BiOX photocatalytic technology in the future are summarized and prospected.
