摘要
随着工业化和城市化进程的加快,水体中污染物种类增多,对生态系统构成威胁.探究金属离子和非金属离子掺杂、贵金属沉积、半导体复合等改性技术以及其在提高光催化剂光吸收范围和光生载流子分离效率方面的作用.结果显示,改性策略能够明显提升材料在可见光下的光催化性能,有效降解包括染料、农药和藻类在内的多种污染物,未来需要关注实际水体中共存污染物的去除以及开发稳定、易回收、循环利用性强的高效光催化剂.
Abstract
With the acceleration of industrialization and urbanization,the types of pollutants in water are increasing,which poses a threat to the ecosystem.In this paper,the modification techniques such as metal ion and nonmetal ion doping,precious metal deposition,semiconductor recombination and their effects on improving the absorption range of photocatalysts and the efficiency of photogenic carrier separation are discussed.The results show that the modification strategy can significantly improve the photocatalytic performance of the material under visible light and effectively degrade a variety of pollutants including dyes,pesticides and algae.Future research needs to focus on the removal of coexisting pollutants in actual water bodies and the development of efficient photocatalysts with stable,easy recovery and strong recycling.
