| 摘 要： | 以钛酸丁酯为钛源,Fe(NO3)3·9H2O为铁源,采用溶胶-凝胶法制备Fe/TiO2纳米粉体,利用溶胶结合静电纺丝技术制备Fe/TiO2纳米纤维,从材料改性及形貌改善两个角度共同提高TiO2纳米材料的光催化活性及实用性。借助XRD、SEM、TEM等分析技术,探究了Fe/TiO2纳米材料在可见光区的光催化活性,分析了煅烧温度及掺铁量对Fe/TiO2纳米材料光催化性能的影响。结果显示,铁的掺入及形貌的改善有助于提高TiO2的光催化性能。

| Abstract: | Using butyl titanate as titanium source and Fe(NO3)3.9H2O as iron source, Fe/TiO2 nano powders were prepared by sol-gel method and Fe/TiO2 nano fibers were prepared by sol-electrostatic spinning technology. The photocatalytic activity and practicability of TiO2 nanomaterials were improved from the aspects of material modification and morphology improvement. By XRD, SEM and TEM, the photocatalytic activity of Fe/TiO2 nano-materials in visible light region was investigated. The effect of calcination temperature and iron content on photocatalytic performance of Fe/TiO2 nano-materials was analyzed. The results show that the addition of iron and the improvement of the morphology are helpful to improve the photocatalytic performance of TiO2. |
