摘要
Bi基氧化物、Bi基卤氧化物和Bi基氧酸盐光催化剂具有独特的电子结构和表面结构特性,然而光催化性能并不令人满意,氧空位作为一种有效手段来调节光电参数,引起了光催化领域的广泛关注。氧空位在光催化性能优化中促进光生电子-空穴对的分离,扩展吸光范围。在此基础上,综述了由于空位的吸附与活化作用,增强了其在H2O分解制氢制氧、还原CO2、固氮以及去除污染物等方面的应用。
Bi-based oxides,Bi-based oxyhalides and Bi-based polyoxometalate photocatalysts have unique electronic structure and surface structure characteristics.However,the performance of photocatalyst is still unsatisfactory.Oxygen vacancy is an effective means to adjust photoelectric parameters,which promotes the separation of photogenerated electron-hole pairs and expands the absorption range in the optimization of photocatalytic performance.On this basis,the application of vacancy adsorption and activation was reviewed to enhance the application of H2O molecular decomposition to produce hydrogen and produce oxygen,reduce CO2,fix nitrogen,and remove pollutants.
