| 摘要: | 使用离子交换法制备了介孔TiO2/CdS纳米复合光催化材料. 利用X射线衍射、高分辨率透射电镜、氮气吸附-脱附分析、红外光谱和紫外-可见漫反射光谱等手段对制备的介孔TiO2/CdS纳米复合光催化材料的微观结构和光吸收性质进行了研究, 并选择染料罗丹明B和茜素红作为底物在可见光下考察了催化材料的光催化活性. 结果表明: 离子交换法制备介孔TiO2/CdS的光催化活性显著高于沉淀法制备的TiO2/CdS. |
| Abstract: | In this report, Mesoporous TiO2/CdS nanocomposite photocatalyst is prepared using ion exchange method. The microstructure and the light absorption characteristics of the prepared mesoporous TiO2/CdS are investigated using XRD, HRTEM, nitrogen isotherm, FTIR and UV-vis diffuse reflectance spectra. The photocatalytic activities of mesoporous TiO2/CdS are tested for photocatalytic degradation of dye Rhodamine B and Alizarin red under visible irradiation. It is found that the mesoporous TiO2/CdS prepared with our ion exchange method shows much higher photocatalytic activity than that prepared with the codeposition method. |
