摘　　要：采用溶胶 凝胶法制备了TiO2 /沸石光催化剂 ,以紫外光为光源 ,用所制备的光催化剂降解了甲基橙、水杨酸、汽巴克隆红、汽巴克隆黄等有机物。结果表明 ,在本实验条件下 ,TiO2 /沸石光催化剂对上述有机物都有较好的降解效果。Titanium dioxide (TiO 2) based photocatalysts were prepared by impregnating molecular sieves ( natural zeolites ) in this study. Under the ultraviolet light and solar light irradiation, methyl orange,salicylic acid etc. organic matters dissolved in aqueous solution were degraded by the photocatalysts we prepared. The experiment results indicated that the TiO 2/zeolite photocatalysts can degrade efficiently these organic matters.
