| 摘 要： | 采用溶胶-凝胶法制备了具有高活性的可见光响应插层膨润土负载掺氮TiO2光催化剂（以下简称光催化剂）。利用IR对光催化剂的微观结构进行表征,并以亚甲基蓝为目标降解物,讨论了光催化剂在可见光下的催化活性。结果表明:氮掺杂TiO2成功负载于插层膨润土片层表面。在尿素掺杂量为0.35g和催化剂用量为40mg条件下,光催化剂对25mL初始浓度为5mg/L的亚甲基蓝溶液的降解率可达99%。 |

| Abstract: | Highly efficient visible-light-induced intercalated bentonite loaded nitrogen-doped TiO2 photocatalystsCphotocatalysts for short)were produced by sol-gel method.The micro-structure of the photocatalysts was characterized by IR,and photocatalytic activity of photocatalysts under visible-light irradiation was discussed with the methylene blue as target degradation products.The results demonstrated that the nitrogen-doped TiO2 was successfully loaded on the surface of the intercalated bentonite.In conditions of the CO（NH2）2 mass of 0.35g and the photocatalysts mass of 40mg,the degradation rate reached 99%for photocatalysts on the methylene blue initial concentration of 5mL/L for 25mL. |
