摘要
纺织行业生产过程中产生大量有机废水,严重危害环境及人体健康,降解废水中有机污染物成为近年来环保领域的研究热点。二氧化钛(TiO2)的非均相光催化是有效降解有机污染物最有前途的技术之一。本文介绍了TiO2的光催化机理并且从金属离子掺杂、非金属离子掺杂、半导体复合、染料敏化等方面综述了提高TiO2光催化效率的研究进展。
A large amount of organic wastewater from textile industry,which seriously impacts on the environment and human health.In recent years,the degradation of organic pollutants in wastewater has become a research hotspot in the field of environmental protection.The heterogeneous photocatalysis of titanium dioxide(TiO2)is one of the most promising technologies for the effective degradation of organic pollutants.In this paper,photocatalytic mechanism of TiO2 was introduced and the latest research progress on improving the photocatalytic efficiency of TiO2 was summarized which include metal ion doping,non-metal ion doping,composite semiconductors,dye sensitization and so on.
