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。

The prepared powders were characterized by XRD, UV-Vis, FTIR, N_2 adsorption, Fluorescence spectroscopy, etc. N-doped TiO_2 evidently shows its absorbance shoulder shift into visible light region. Moreover, N-doping retards the transition of TiO_2 from anatase to rutile type as well as restrains the growth of the crystal size which leads to less decrease of surface area. These characteristics are considered to benefit the photoactivity of TiO_2; When all the samples were applied to the photodecomposition of Methylene Blue under visible light(λ＞400 nm), the N-doped TiO_2 show an obvious superiority when compared to the undoped TiO_2, the active hydroxyl groups are found to play a important role in this high photoactivity; When the same experiment was performed under UV light, all the samples show the consistent sequence of photoactivity as in the visible light.

通过UV-Vis、XRD、BET、IR、FL等表征手段测试表明：掺氮不仅使TiO_2的光吸收区域拓展到可见光区，而且有利于延缓TiO_2晶相的转换，从而抑止了高温煅烧下所引起的晶粒增大以及比表面积的降低，且氮源浓度越高，此现象越明显，这些特征都有利于催化剂光催化活性的提高；在主波长大于400nm的可见光催化亚甲基蓝实验当中，掺氮TiO_2的光催化活性明显优越于未掺氮样品，亚甲基蓝在90min内达到88％的脱色率。
