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... Many organic pollutants (such as halogenated hydrocarbons, surfactants, polychlorinated biphenyls, dyes, etc.) that are difficult to be degraded by other methods can undergo mineralization degradation under the photocatalysis of TiO2 and are oxidized to CO2, H2O Such as simple inorganic matter, the environment will not bring secondary pollution [1 ~ 3]. In recent years, the preparation of TiO2 nanocrystalline (or microcrystalline) film and photocatalysis ...
