| 摘 要： | 采用静电纺丝和程序升温焙烧的方法制备了NiO/TiO2纳米复合光催化剂. 利用X射线衍射(XRD)、扫描电子显微镜(SEM)、拉曼光谱(Raman)、紫外可见漫反射光谱(UV-vis DRS)等测试技术对样品的结构与性能进行了表征, 并研究了该催化剂在可见光下对有机染料罗丹明B催化降解反应的活性. 结果表明, 合成的NiO/TiO2复合纳米材料尺寸均匀, 该催化剂相对于纯的TiO2具有更强的紫外光吸收性能, 煅烧温度为600℃时, NiO/TiO2的光催化活性最高. 而且, 该催化剂也可被循环使用, 这使得该复合光催化剂具有广阔的应用前景. |

| Abstract: | NiO/TiO2 nanofibers composite photocatalyst were synthesized by electro-spinning and calcinations methods. The fibers were detected by XRD, SEM, Raman and UV-vis DRS, respectively. Photocatalytic properties of NiO/TiO2 were studied by method of degradation of Rhodamine B, an organic dye, in visible light. The results showed that the as-synthesized NiO/TiO2 nanofibers have uniform-sized di-ameter, and the UV absorbing properties of NiO/TiO2 were enhanced compared with those of pure TiO2. The photocatalytic activity of NiO/TiO2 is the greatest when the calcining temperature is 600℃. The NiO/TiO2 photocatalyst could be reused, which is essential to the potentially practical application. |
