摘　　要：介绍了近年来国内外有机物废水光催化降解的研究现状,及不同催化剂体系对各种有机物的降解效果。通过对以TiO2为主的光催化剂在不同催化剂结构和不同反应因素等条件下降解效果的比较,论述了TiO2光催化剂的优越性、不足和影响机制。并指出了光催化降解有机物废水技术需要进一步解决的问题。Photo-catalytic degradation of organic contaminants is currently a research focus. Recent progress in photo-catalytic degradation of organic contaminants is reviewed, and degradation of organic pollutants based on various types of photo-catalysts is also summarized. Effects of photo-catalysts under different reaction conditions, such as heat treatment temperature, pH, dosage of photo-catalysts and reactor, are compared. The conclusion will provide theoretical basis for future research and industrialization of photocatalysis technology. In the meantime, the existing problems of this technology are put forward.
