| 摘 要： | 采用溶胶-凝胶法,制备了纳米Fe3+/TiO2薄膜,利用XRD、TEM等测试手段进行了样品的表征分析,以降解含阿奇霉素废水为反应模型,研究了纳米Fe3+/TiO2薄膜的紫外光照射催化活性及薄膜的重复使用效果。结果表明,纳米Fe3+/TiO2薄膜不易失活,其催化活性寿命较粉体纳米Fe3+/TiO2的强,且再生性能好,薄膜重复使用4次,仍有明显的降解效果。

| Abstract: | Nanometer Fe3 /TiO2 film was prepared by sol-gel method,the surface morphology of samples was characterized by XRD and TEM,the UV photocatalytic activity was measured by degradation using photocatalytic degradation Azithromycin waster water as a model reaction,and using life of film was investigation.The results show that Fe3 /TiO2 film is not easy to lose activity,its longevity is longer than nanoparticle Fe3 /TiO2,and the films have good regeneration property,degradation efficiency of film was still high after reusing four times. |
