摘　　要：随着工业的发展,一些地区的水资源遭到了破坏,特别是发展中国家,水污染已经成为一个严重的环境问题,在各种处理方法中,光催化是解决环境污染的一种很有前途的方法。TiO2由于具有高光催化活性、无毒、化学物理性质稳定等特点,在光分解水中的有机物方面受到了广泛的关注。然而,由于TiO2宽带隙结构缺陷,光催化效率不高。因此,设计合成高效TiO2光催化剂成为研究热点,文章介绍了TIO2的光催化原理,综述了近3年取得的新成果。With the development of industries,the water resources in some regions have been destroyed.Water pollution has become a serious environmental problem,especially in developing countries.Among various processing methods,photocatalysis is a promising approach to solve environmental pollution problems.TiO2 has been studied extensively in photo-decomposition of organics in water because of its high photocatalytic activity,non-toxicity and outstanding chemical-physical stability.Nevertheless,TiO2 has low photocatalytic efficiency due to its wide band gap structure.Therefore,the design and synthesis of highly-efficient TiO2 photocatalysis has become a research hotspot.This paper introduces the photocatalysis principle of TiO2 and summarizes the new achievements in recent three years.
