【摘要】 采用溶胶-凝胶法,制备了Ag+/TiO2薄膜。利用XRD、SEM等测试手段进行了样品的表征分析,以降解罗丹明B为反应模型,研究了薄膜的日光催化活性和薄膜的重复使用效果。结果表明,Ag掺杂以后可以明显地提高TiO2薄膜的催化活性,薄膜的使用次数可达到5次以上,且仍有明显的降解效果。更多还原

【Abstract】 Ag⁺/TiO₂ film was prepared by sol-gel method,the surface morphology of samples was characterized by XRD and SEM.Light photocatalytic activity was measured by using photocatalytic degradation Rodanmine B as a model reaction.Using life of films was investigated.The results show that light photocatalytic activity of TiO₂ film could be increased greatly after doping Ag⁺.Degradation efficiency of film was still high after using more five times.更多还原
