摘　　要：通过湿式浸渍法合成二元AgCoO_(2)/g-C_(3)N_(4)催化剂,以四环素为目标污染物,评价了AgCoO_(2)/g-C_(3)N_(4)协同H_(2)O_(2)的光催化活性。结果表明,在可见光条件下,AgCoO_(2)/g-C_(3)N_(4)协同H_(2)O_(2)降解四环素的效果显著,最佳降解效率达到92.19%;同时催化剂表现出良好的循环稳定性和较宽的pH适应范围。此外,对光催化剂的结构、微观形貌和光学特性进行表征分析,AgCoO_(2)的引入改善了g-C_(3)N_(4)的光响应范围及光生载流子的分离性能。AgCoO_(2)/g-C_(3)N_(4),a binary composite catalyst,is synthesized through wet impregnation method,and its photocatalytic activity synergized with H_(2)O_(2)is evaluated by taking tetracycline as target pollutant.The results show that AgCoO_(2)/g-C_(3)N_(4)synergized H_(2)O_(2)can effectively degrade tetracycline under visible light condition,with the optimal degradation efficiency reaching 92.19%.Meanwhile,the catalyst exhibits a good cycling stability and a wide pH adaptation range.In addition,the structure,micromorphology and optical properties of the catalyst are characterized and analyzed,it is verified that the addition of AgCoO_(2)improves the optical response range of g-C_(3)N_(4)and the separation performance of photogenerated carriers in g-C_(3)N_(4).
