摘　　要：采用炭化方法制成规整炭化物载体,在其上负载TiO2经烧结成为规整型光催化剂.利用XRD和BET技术对载体和催化剂样品进行了表征.考察了样品的光催化活性.结果表明,规整炭化物载体为多孔物质,以中孔和微孔为主,平均孔径2.1 nm.负载型的规整光催化剂有明显的光催化效果.实验中还探讨了气相光催化反应的动力学过程.Regular carbide support is prepared through carbonization process,and TiO2 is loaded on the support to form regular phtocatalyst. Structures of the support and the catalyst are characterized by means of XRD and BET techniques,and photocatalytic activity of the regular catalyst is evaluated. It is found that the support is a kind of porous material,with macropores,mecropores and micropores existing on it all together and the mean pore size being 2. 1 nm. Besides, kinetics of gas-phase photocatalytic reaction is also studied.
