采用溶胶-凝胶法制备了 Co-TiO2催化剂。研究了不同掺钴量和焙烧温度下,催化剂的可见光光催化和类Fenton活性,并通过XRD、UV-DRS和 XPS对催化剂的结构进行表征,分析了催化机理。结果表明,Co2+掺杂使Co-TiO2同时获得了可见光光催化和类Fenton活性。当掺钴量为1.0%,500℃焙烧时,苯酚的光催化降解率达到52.3%,类 Fenton 降解率为65.3%。
The Co-TiO2 catalysts were prepared by the sol-gel method,and their catalytic activities were meas-ured by the degradation of phenol with different Co2+ doping dosage and calcinations temperature.The catalytic mechanism was studied through XRD,UV-DRS,XPS and degradation tests.The results showed that the cata-lysts represented the visible light photocatalytic and Fenton-like catalytic activities.When the cobalt doping dosage was 1.0% and the calcinations temperature was 500 ℃,the degradation rates of phenol were reached 52.3% of photocatalytic process under visible light and 65.3% of Fenton-like reaction.
