摘要 用含有AgNO3的复合溶胶凝胶制备Ag/TiO2薄膜,然后对其进行了SEM,XRD,RBS研究,以甲基橙为反应物检验了含有不同n(Ag)/n(Ti)的Ag/TiO2薄膜在365 nm紫外光作用下的光催化降解效率.具有最佳光催化降解效率的是溶胶中n(Ag)/n(Ti)=0.064的Ag/TiO2薄膜,与未掺银TiO2薄膜相比,效率提高了73%. The catalytic phtodegradation of methyl orange (MO) with 365 nm irradiation on TiO2 and n(Ag)/n(TiO2) thin films is investigated in aqueous solution. With a silver loading ratio of n (Ag)/n (Ti)= 0. 064(in sol), 73% enhancement of catalytic efficiency is observed.
