摘要
介绍了纳米 Ti O2 的光催化机理、制备方法及在降解水中有机污染物和环境净化方面的近期应用研究进展 ,并对目前存在的问题及今后的发展方向进行了讨论。
Nanosized TiO 2 is applied extensively in environmental field as a promising photocatalyst. In this paper,the photocayalystic mechanism, the preparation of nanosized TiO 2, and the recent research results on photocatalystic degradation of organic contaminants in water and air are reviewed. Key problems and future research needs are raised.
