摘要: 用溶胶-凝胶技术在多孔阳极氧化铝模板的有序微孔内制备了高度取向的TiO2纳米线阵列膜光催化剂.用XRD,AFM和SEM等手段对样品进行了表征.结果表明,TiO2纳米线阵列膜晶型为锐钛矿,从AFM图像中可以看出TiO2纳米线线径分布均匀一致,取向性极好,直径与AAO模板的孔径大小一致.以其对吖啶橙的降解效果作为评价光催化活性的标准,与相同条件下制备的TiO2/玻璃膜相比,TiO2纳米线阵列膜具有很好的催化活性.

Abstract: TiO2 nanowires array film was prepared within the pores of anodic aluminum oxide(AAO) template bYUsing sol-gel chemistry. This method was suitable for solving the problems caused by the generallYUsed sol-gel method, i.e. the agglomeration between particulates of the catalyst film in the burning process and the catalyst from the supports in the reaction. Anatase crystal form of TiO2 nanowires film was shown through XRD characterization and the diameter was determined by the pore size of the AAO template bYUsing AFM image, respectively. The photocatalytic activity of TiO2 nanowires array film measured bYUsing an acridine dye solution as a modeLIs higher, compared with that of TiO2/glass film.

Key words: TiO2 nanowires array film, Anodic aluminum oxide(AAO), Acridine orange, Photocatalysis
