摘　　要：采用光催化还原法制备了载银纳米管钛酸,通过TEM可以看到纳米管钛酸表面附着有银颗粒,XPS和XRD等结果显示银颗粒是以单质银的形式存在.对亚甲基蓝光催化降解实验结果表明:载银纳米管钛酸催化剂的催化活性比未载银纳米管钛酸催化剂的活性高.The Ag loaded nanotube titanic acid was prepared by the photo-reduction method. The photograph of TEM showed that Ag particles deposited on the surface of the nanotube titanic acid. Results of XPS and XRD indicated that the Ag^＋ was reduced to metal. The results of photodegradation of methylene blue showed that the photocatalytic activity of Ag loaded nanotube titanic acid was higher than that of the nanotube titanic acid.
