摘要
采用表面溶胶-凝胶法制备碳纳米管负载TiO2光催化剂,通过改变负载次数制备不同TiO2负载量的光催化剂.采用XRD,SEM,BET以及TG-DSC对该催化剂进行了表征.采用结晶紫光催化降解,研究碳纳米管负载二氧化钛的光催化活性.光催化测试结果表明,该碳纳米管负载TiO2光催化剂在紫外光照射下具有比TiO2(P25)光催化剂更优越的光催化降解结晶紫的活性.
In this paper, the photocatalysts of carbon nanotube supported TiO2 with different amount ot： titania were prepared by using surface sol-gel method, changing the number of surface sol-gel cycles. The photocatalyst of carbon nanotube supported TiO2 was characterized by XRD, SEM, BET, and TG-DSC. The photocatalytic activities for the photodegradation of crystal violet on the photocatalysts were investigated. The results of photocatalytic test show that the carbon nanotube supported TiO2 shows much better photocatalytic activity for the photodegradation of crystal violet than TiO2 （P25） under UV irradiation.
