摘要
从氧缺陷、离子掺杂、与铋基半导体材料复合、表面修饰改性以及多种策略联合改性等方面对Bi_(2)O_(3)以及混合价态氧化铋(Bi_(x)O_(y))的改性研究现状和不同改性策略的活性提高机制进行综述,并对氧化铋材料在能源、环境光催化领域的应用研究进行总结。为克服氧化铋光生载流子复合率高、载流子传输能力低等问题提供参考。
The research status and different modifications of Bi_(2)O_(3)and mixed valence bismuth oxide(Bi_(x)O_(y))are modified from the aspects of oxygen deficiency,ion doping,composite with Bi-based semiconductor materials,surface modification modification,and multiple strategies combined modification.The research status of the modification of Bi_(2)O_(3)and mixed valence bismuth oxide(Bi_(x)O_(y))and the activity improvement mechanism of different modification strategies are reviewed,and the application research of bismuth oxide materials in the fields of energy and environmental photocatalysis is summarized.It provides a reference for overcoming the problems of high recombination rate of bismuth oxide photogenerated carriers and low carrier transport ability.
