    摘要:

    以鈦酸丁酯為鈦源,Fe(NO3)3.9H2O為鐵源,采用溶膠-凝膠法制備Fe/TiO2納米粉體,利用溶膠結(jié)合靜電紡絲技術(shù)制備Fe/TiO2納米纖維,從材料改性及形貌改善兩個(gè)角度共同提高TiO2納米材料的光催化活性及實(shí)用性。借助XRD、SEM、TEM等分析技術(shù),探究了Fe/TiO2納米材料在可見光區(qū)的光催化活性,分析了煅燒溫度及摻鐵量對(duì)Fe/TiO2納米材料光催化性能的影響。結(jié)果顯示,鐵的摻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.
