摘要
TiO2光催化反应能有效降解对环境有害的多种污染物,使其转化为H2O,CO2及其它无机小分子物质。文章综述了TiO2光催化反应机理以及TiO2的表面修饰方法,并对近年来TiO2光催化在废水处理中的应用进行了扼要的介绍。
TiO_2-based photocatalysis has the potential to degrade environmental pollutants. The contaminants can be mineralized to CO_2, H_2O and other small molecules. The paper deals with the principle and mechanism of photocatalysis on TiO_2, and the surface modification methods of TiO_2. The recent developments in TiO_2 photocatalysis and its application prospects for the treatment of waste water are also introduced.
