| Abstract: | 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 TiO_2 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. |
