微波改性Ce/TiO2光催化剂的制备及其降解活性艳红3BS的研究

摘要

TiO2 and Ce/TiO2 photocatalyst was prepared by sol-gel methods,and then treated with microwave. The microstructure of prepared nano photocatalyst was characterized by X-ray diffraction (XRD). The results showed that the photocatalytic degradation effect of Ce-doped and mricrowave treated TiO2 was superior to that of single Ce-doped TiO2, and single Ce-doped TiO2 was superior to un-doping TiO2.%利用溶胶-凝胶法合成了TiO2及Ce/TiO2光催化剂,并用微波进行处理.借助XRD对合成的纳米光催化剂微观结构及性能进行了研究.结果表明:TiO2经铈掺杂并经微波改性后的光催化降解效果优于单独铈掺杂改性的TiO2,铈单独掺杂改性的TiO2的光催化降解效果优于未掺杂改性的TiO2.
