    摘要:

    利用分子自組裝技術(shù)在載波片上制備了銳鈦相TiO2及WO3摻雜的TiO2薄膜。利用原子力顯微鏡(AFM)和UV-VIS-NIR分光光度計對薄膜進行了表征。利用對羅丹明B的降解評價了所制備薄膜的光催化活性。結(jié)果表明：當W／Ti=2at％時，TiO2薄膜的光催化活性得到提高。

    Abstract:

    Anatase phase TiO2 and WO3-doped TiO2 thin films were prepared on microscope glass slides by self-assembly method. The films were characterized by atomic force microscope (AFM) and UV-VIS spectrophotometer. The photocatalytic activities of the films were tested on the degradation of rhodamine B dye. The results indicate that when the atom ratio of W/Ti is 2at%, the photocatalytic activity of the TiO2 is improved.
