摘要
TiO_(2)光催化技术凭借TiO_(2)优良的光电性能,在消除水环境有机污染物方面有着广泛的应用前景,其作为光催化剂时通过紫外光或小范围太阳光生成的·OH和·O_(2)^(-),几乎能够将有机物完全矿化,且无二次污染。介绍了高级氧化法中的光催化氧化的基本原理,详细论述了近年来国内外TiO_(2)光催化改性方法应用现状,提出多种改性方法协同的发展方向。
Titanium dioxide has excellent photoelectric properties.When it is used as a photocatalyst,hydroxyl radicals and superoxide radicals generated by ultraviolet light or small range of sunlight can almost completely mineralize organic matter without secondary pollution.In this article,the basic principle of photocatalytic oxidation in advanced oxidation method was introduced.The application status of photocatalytic modification methods of TiO_(2)at home and abroad in recent years was discussed in detail,and the development direction of synergistic modification methods was put forward.
