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。Using butyl titanate as titanium source and Fe(NO3)3·9 H2O 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.
