摘　　要：复合可见光催化剂具有高效的可见光催化活性、化学性能稳定、应用价值高等优点,在污水处理和光催化杀菌方面都有很广泛的应用。本课题研究了Ag复合TiO_2可见光催化剂的制备及其催化降解甲基橙的活性和对大肠杆菌的杀菌性能的研究。结果表明:在可见光照射条件下(λ>400 nm)复合材料对甲基橙的降解效率在120 min可达到96%,对大肠杆菌的杀菌效率60 min可达到99.75%,具有很高的应用价值。The visible-light photocatalysts composite have wide application in sewerage and photocatalytic sterilization because of the high efficiency, chemical stability and high value of application. In this study, we have research the preparation of the composite and the photocatalytic activity to the degradation of MO and sterilization of E.coli. We can conclusion that the photocatalytic degradation efficiency of the composite to MO can reach 96 % within 120 rain and the photocatalytic sterilization activity to the E.coli can reach 99.85 % in an hour under the visible light irradiation （λ〉400 nm）.
