摘　　要：以钛酸四丁酯为前驱体,冰醋酸为水解抑制剂,用溶胶-凝胶法制备了纳米Ag/TiO2复合催化剂,测定了催化剂对茜素红溶液的光降解活性。结果表明,Ag/TiO2催化剂具有较高的光催化活性。Using tetrabutyl titanate as the precursor and glacial acetic acid as the hydrolysis inhibitor, Ag/TiO2 catalyst was prepared by means of sol-gel method. The photo-degradation activity of the as-prepared catalyst for alizarin red was investigated. The results showed that Ag/TiO2 catalyst exhibited better catalytic properties.
