Bismuth ferrite is a perovskite-type semiconductor photocatalyst, and has been attracted wide interests due to its proper optical band gap, good chemical stability and visible light absorption. However, the high photogenerated electron-hole pair recombination rate and low carrier efficiency of bismuth ferrite leads to its weak photocatalytic activity and limits its practical application. The structure and photocatalytic mechanism of bismuth ferrite is summarized. The mechanism and research progress of bismuth ferrite modification methods such as precious metal deposition, semiconductor compoun...
