Abstract: Bismuth-containing photocatalysts can be used in many fields because of narrow band gap and ability of adsorbing visible light. In this paper，the latest research status and progress of bismuth-containing photocatalysts are reviewed. Bismuth oxide，halide bismuth oxide，bismuth titanate，bismuth tungstate，bismuth vanadate，bismuth molybdate and bismuth ferrite are introduced and the methods of improving photocatalytic performance are highlighted，including improvement of synthesis methods，photocatalysts doping and preparation of photocatalyst composites. Finally，the research directions of bismuth-containing photocatalysts are presented，aimed at improving overall performance and realizing industrial application of bismuth-containing photocatalysts，such as preparing multi-doped photocatalysts，multiple photocatalyst composites and supported catalysts.
