【摘要】以非离子表面活性剂三嵌段共聚物聚环氧乙烯醚-聚环氧丙烯醚-聚环氧乙烯醚P123和聚乙二醇(PEG)为复合模板剂,采用溶胶-凝胶法制备了介孔TiO2光催化剂。研究了催化剂制备条件和反应条件对光催化性能的影响。Y掺杂后,催化剂的可见光催化降解甲基橙活性增加。用BET、XRD和FT-IR等对催化剂进行了表征。更多还原

【Abstract】 Using polyethylene glycol and non-ionic surfactant triblock copolymer P123 as the structure directing agents,photocatalysts of mesoporous TiO2 were prepared by sol-gel method.The effect of preparation and reaction conditions on photocatalytic property was studied.The visible photocatatlytic activity was increased after rare earth Y was doped into mesoporous TiO2.The photocatalysts were characterized by BET,XRD and FT-IR.更多还原
