Recent advances in bismuth-based visible light photocatalysts

Bismuth-based visible light photocatalysts has attracted much attention due to its effectiveness in degrading and mineralizing the recalcitrant organic compounds utilizing the solar visible light spectrum.The recently published works of bismuth oxyhalides,bismuth tungstate,bismuth titanate,bismuth vanadates,bismuth molybdates,composite bismuth-based catalysts and so on are reviewed and summarized,and their photocata wtic oxidation mechanism are discussed.Extensive future research will be focused on the development of new kind of visible light photocatalyst and mechanism of photocatalytic oxidation.
