| 摘 要： | 以尿素为氮源,钛酸正丁酯为钛源,采用溶胶-凝胶法制备氮掺杂纳米TiO_2。通过红外光谱(FT-IR)、X-射线衍射(XRD)、紫外-可见吸收(UV-Vis)光谱和扫描电镜(SEM)等测试手段对材料的结构和形貌进行表征;以甲基橙模拟有机污染物,研究样品的光催化活性。结果表明,氮掺杂纳米TiO_2为锐钛矿型结构,尺寸均匀,分散性好,对甲基橙染料具有极好的光催化活性,降解率达到97%左右。

| Abstract: | The nitrogen-doped nano-TiO2(N-doped nano-TiO2) was prepared by sol-gel method with urea as nitrogen source and tetrabutyl titanate as titanium source.The crystal structure and morphology of the samples were characterized by FT-IR,XRD,UV-Vis and SEM,respectively.The photocatalytic activity of the obtained N-doped nano-TiO2 was investigated through degradation of the methyl orange.The results show that the N-doped nano-TiO2 has the anatase structure and a uniform particle size distribution with excellent dispersibility,and the degradation rate to methyl orange can be reached to 97％ showing a superb photocatalytic performance. |
