Pt/TiO_2催化剂上苯的光催化降解

Photocatalytic degradation of benzene over Pt/TiO_2

以TiO2、Pt TiO2为光催化剂,光催化降解苯为模型反应,比较了两者的光催化活性,并利用在线气相色谱及原位红外考察了反应中间物及产物分布.结果表明铂的负载有利于反应中间产物的进一步降解,从而提高光催化降解效率.

The distribution of the intermediates and products produced in the heterogeneous photocatalytic degradation of benzene over TiO_2 and Pt/TiO_2 was investigated by GC and in-situ FTIR methods. The results suggested that the platinized TiO_2 was favor the degradation of the intermediates, leading to the improvement of the performance of the photocatalytic reaction.
