摘要 以TiO2为催化剂,催化氧化法处理污水是近年来兴起的一种现代水处理技术,本文介绍了提高TiO2光催化剂催化效率,及对催化剂进行改性的方法,主要的手段主要有以下几个方面:减小催化剂尺寸、沉积贵金属、掺杂金属离子、光催化剂负载化、半导体复合等。介绍了国内外近年来有关多相光催化反应中光催化反应器设计与研究的进展情况。 Photocatalytic oxidation using TiO2 as photocatalyst is a modem technology for water treatment developed in recent years. This paper introduces the methods to increase catalysis efficiency of TiO2 and to modify the catalysis of catalyst. There are a few means, such as decreasing size of catalyzer, sedimentating noble metal, doping metal ions, loading photocatalyst and compositing semiconductor. Additionally, the development of design and research on photocatalytic reactors concerning multi-phase photocatalysis is introduced.
