摘　　要：制备了纳米复合催化剂TiSiW12O40/TiO2,利用IR、XRD和TEM对其进行了表征.研究了钨硅酸的负载量、溶液pH值、溶液浓度、光照时间等对TiSiW12O40/TiO2光催化降解亚甲基蓝的影响.TiSiW12O40/TiO2光催化降解亚甲基蓝的反应符合一级反应动力学.The nanosized complex photocatalyst TiSiW12 O40/TiO2 were prepared by sol-gel method,and characterized by IR spectra, XRD and TEM. The effect of the content of H4 SiW12O40 ·12H2O in catalyst, pH value of solution, concentration of methylene blue and reaction time on photocatalystic degradation for methylene blue using TiSiW12O40/TiO2 were investigated,which photodegradation is first order reaction.
