摘　　要：Bi2O3具有较强的可见光催化活性被广泛用于有机物的光催化降解研究。综述了Bi2O3的光催化性能、存在的主要问题以及解决方法。Bi2O3基复合光催化剂、金属掺杂以及量子点修饰可以进一步增强Bi2O3的光催化活性和抗光腐蚀性,适当的金属掺杂能增强Bi2O3催化剂的结构稳定性。As one of the visible light-activated photocatalysts, Bi2O3 has been widely used in photocatalytic degradation of organic compounds. The catalytic performance of Bi2O3, the main problems existed and their solutions are summarized. For the fabrication of Bi2O3 based composite photocatalyst, the strategy of the metal doping and Bi2O3 quantum dots, the photocatalytic activity and photo corrosion resistance of Bi2O3 can be enhanced, furthermore, the appropriate metal doping can improve the structure stability of Bi2O3.
