| 摘 要： | 制备高活性可见光响应型掺钒TiO2光催化剂,以荧光灯为光源,光催化降解亚甲基蓝为模型反应,对可见光下TiO2的催化活性进行评价。研究了掺钒TiO2制备方法、掺钒量及氧化剂对光催化氧化的影响。结果表明,溶胶-凝胶法制备的TiO2催化活性较高,且工序简单,钒离子掺杂均匀;掺钒能使TiO2具有可见光响应,最佳掺钒量为1%;外加氧化剂H2O2能提高掺钒TiO2催化活性。

| Abstract: | Vanadium doped TiO_2 was prepared by sol-gel method and common deposition method.The test on photocatalytic degrading of methylene blue(MB) under visible light was carried out using TiO_2 as catalyst and fluorescence light as simulation light resource.The effects of preparation methods,vanadium dosage and additional oxidant on photocatalytic oxidation were investigated.It's found that the sol-gel method is easy to control,V is well-proportioned in sample and photocatalytic activity of TiO_2 is high.TiO_2 have visible light response by vanadium doped,the best vanadium dosage was 1%,the additional oxidant H_2O_2 can improve vanadium doped TiO_2 photocatalytic activity. |
