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.

利用正相和反相胶束介质模板制备的纳米TiO2为光催化剂，在紫外光照射下，对染料罗丹明B和有机有毒无色小分子2，4-二氯苯酚进行光催化降解，研究了其光催化性能，并对光催化过程中氧化物种及降解产物进行了跟踪测定，结果表明，反相胶束模板体系制备的纳米TiO2与正相胶束介质制备的纳米TiO2比较，在紫外照射下对RhB及DCP的降解有较好的光催化性能，对RhB在160min尤催化矿化率可达95%，光催化反应主要的氧化物种涉及在基自由基。
