摘　　要：采用溶胶-凝胶法制备了Ag、Cu共掺TiO_2催化剂,研究了Ag、Cu掺杂比例对TiO_2光催化效果的影响。通过X射线衍射仪、扫描电子显微镜、紫外-可见分光光度计、紫外-可见漫反射分别表征了催化剂的结构、形貌、光吸收及光催化性能。结果表明:以适当比例掺杂Ag、Cu能显著提高TiO_2光催化剂对阿昔洛韦的去除能力,Cu、Ag掺杂量分别为1.2%、1.5%(均为摩尔分数)的TiO_2光催化剂对阿昔洛韦的去除率高达98.8%。（Ag,Cu）co-doped TiO2 photocatalysts were prepared by sol-gel method,and the effects of different doping ratios were studied.The structure,morphology,photoabsorption and photocatalytic properties of catalysts were respectively characterized by X-ray diffraction,scanning electron microscope and UV-Vis spectrophotometer.The results showed that the removal rate of acyclovir can be improved significantly by TiO2 with appropriate proportion of Cu and Ag.The removal rate of（Ag,Cu）-TiO2 with the best co-doping proportion（Cu：1.2 mol%,Ag：1.5 mol%）achieved 98.8%.
