摘要

BiOIO3 is a layered semiconductor photocatalyst,which has good chemical properties and has attracted wide attention from researchers because of its unique structure.However,pure BiOIO3 has defects such as insufficient response to visible light and easy recombination of photogenerated electrons.Therefore,in recent years,scholars have tried to modify BiOIO3 to expand its light absorption range,reduce the recombination of photogenerated electron-hole pairs and reduce its limitations,thereby improving its visible light catalytic performance.Current researches focus on the improvement of the catalytic activity of photocatalytic materials from morphology control,precious metal deposition,ion doping and construction of heterojunctions.
