摘　　要：水中许多难于被其它方法降解的有机污染物（例如卤代烃、表面活性剂、多氯联苯、染料等）能在ＴｉＯ２的光催化作用下发生矿物化的降解反应，被氧化为ＣＯ２、Ｈ２Ｏ等简单的无机物，对环境不会带来二次污染［１～３］．近年来有关ＴｉＯ２纳米晶（或微晶）膜的制备与光催...A novel reaction device is reported, in which photocatalytic and photochemical actions on aniline take place simutaneously. It is made up of supported TiO2 film electrode, RuTi electrode and air electrode. The reaction substance of the air electrode is oxygen and the main product is H2O2. The results show that aniline is degraded in higher rate in the system than in single photocatalytic or photochemical system.
