The TiO2 synthesized by normal and reverse micelles as templated were applied for phot ocatalytic of Rhodamine B and organic toxic small molecule 2.4-dichlorophenol under ultraviolet irradiation. Oxidation species and photodegradation products in the photoreaction process were detected for studying their photocatalyst properties. The results showed that: the R-TiO2 had a better photocatalysis property under UV irradiation when photodegradation of RhB and DCP compared to the N-TiO2. After 160min, the mineralized rate of RhB can be 95%. And the oxidative species was mainly referred to OH radical.
