【摘要】 采用溶胶凝胶法和沉淀浸渍法制备了Fe、S、Ce共掺杂TiO2光催化剂A和B,通过SEM对其进行了表征,以酸性蓝为模板对A、B两种催化剂(A是溶胶凝胶法制备的共掺杂TiO2光催化剂、B为沉淀浸渍法制备的共掺杂TiO2光催化剂)活性进行了评价;结果表明沉淀浸渍法制备的光催化剂B的活性强,且其粒子团聚少、分散均匀、能多次重复使用。更多还原

【Abstract】 Using the sol-gel method and precipitation were prepared by impregnation of Fe,S,Ce,Co-doped TiO2 photocatalyst A and B,were characterized by SEM.Acid Blue template of A,B two catalysts(A sol gel prepared co-doped TiO2 photocatalyst,B for precipitation impregnation method prepared codoped TiO2 photocatalyst) activity was evaluated,and the results showed that precipitate prepared by impregnation photocatalyst B activity,and its small particle agglomeration uniformly dispersed.更多还原
