近年来,环境污染越来越被人们所关注,水污染问题更是日趋严重.
In recent years, environmental pollution, more and more people concern water pollution is more and more serious.
利用TiO2类催化剂降解水中有机污染物的研究成为环保工作中的一个热点,但是粉末状TiO2具有机械强度低、分散性差、易团聚、易失活、难分离等缺点因此,为了避免团聚和方便回收,研究人
Use of TiO2 catalyst degradation of organic pollutants in water environment has become a hot spot in the work, but TiO2 possesses the mechanical strength low powder, poor, easy to reunite dispersibility, volatile disadvantages such as live, difficult separation, therefore, to avoid reunion and convenient recovery, researchers
