用四种金属卟啉（CoTHPP、CoTPP、NiTHPP和NiTPP）敏化氮掺杂的TiO 2粉体（N-TiO 2）。采用XRD、TEM、XPS、DRS和N2吸附等手段对材料进行了表征。结果表明，卟啉的存在对N-TiO 2的晶体结构和形貌没有影响，但经金属卟啉敏化后，N-TiO 2的比表面积增加。光催化降解甲基蓝（MB）的实验表明，金属卟啉敏化的N-TiO 2复合催化剂，尤其是CoTHPP/N-TiO 2和CoTPP/N-TiO 2，比未敏化的N-TiO 2具有更高的降解效率。复合催化剂对亚甲基蓝的光催化降解均符合一级动力学模型。该复合催化剂可重复使用4次，光催化活性无明显损失。
Nitrogen doped anatase TiO2powders (N-TiO2) were sensitized by four kinds of metalloporphyrins (CoTHPP, CoTPP, NiTHPP, and NiTPP). The resulting materials were characterized by XRD, TEM, XPS, DRS and N2adsorption. The results showed that the crystal structure and morphology of N-TiO2were not affected by the existence of porphyrin on its surface, but the surface area increased after the N-TiO2sensitized by metalloporphyrins. The photocatalytic degradation of methyl blue (MB) experiments showed that the metalporphyrins sensitized N-TiO2composite catalysts, especially the CoTHPP/N-TiO2and CoTPP/N-TiO2, exhibited higher degradation efficiency than the unsentisized N-TiO2powders. In addition, the photocatalytic degradations of MB using the composite catalysts were all demonstrated to follow first-order kinetic model. The composite catalysts can be recycled four times without significant loss of photocatalytic activity.
