In this paper,different sequence TiO_2-FeOOH nanocompsite films on Na-modifying montmorillonite( MdMmt) substrate were prepared by a molecular self-assembly method. The photocatalytic activity of TiO_2-FeOOH composite films under natural light irradiation in the thiamphenicol solution was studied. The samples were carried out to characterize with TEM,UVVis,FT-IR. The results indicated that the TiO_2-FeOOH nano-films were composed of anatase and goethite,their UV-Vis spectras response range in photocatalysis...

Ti O2具有化学稳定性高、氧化能力强、光催化活性高,无毒等优点,是当前应用最为广泛的纳米功能材料.但其也存在只能被紫外线激发、光生电子-空穴复合率较高等弊端[1].并且在光降解液相中污染物时,表面易积累中间产物,导致光催化剂活性大大降低[2].这极大提高了Ti O2的使用量和?
