摘要
光催化降解水中有机污染物是一项颇有发展前途的废水处理技术。目前主要的研究工作由紫外光逐步向可见光催化方向发展,使这项技术向实用性又迈进了一步。系统介绍了纳米TiO2的光催化降解有机污染物的原理,光催化处理水的现状,并从离子掺杂、表面光敏化和分子筛负载几个方面综述了可见光化的研究现状和发展方向。
Photocatalytic degradation of organic contaminants is a prospect technology in wastewater treatment. The researching focus has been changed from UV to visible light catalysis, which makes photocatalytic technology more practical. In this paper, the principle of TiO2 photodegradation and the current status of photocatalysis in water treatment are introduced systemically. The authors summarize the research status and the developing direction of visible-lighting of photocatalyst from three aspects, ion adulteration, surface photosensitization and zeolite supporting.
