Template Synthesis and Photocatalytic Activity of TiO2 Nanowires Array Film

Abstract

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
