Research Progress in Photocatalytic Modification Methods of TiO2
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 TiO2 at home and abroad in recent years was discussed in detail,and the development direction of synergistic modification methods was put forward.
