Abstract

The microstructure and photocatalytic characteristics of anodic TiO ₂ film have been investigated for applications in waste water treatment. The major structure of the fabricated anodic TiO₂ film consisted of porous cell structure, of which the main crystal structure bas been found to be anatase type. The photocatalytic efficiencies of anodized TiO ₂ were evaluated by the degradation rate of aniline blue and the chemical states of anodic film were estimated by P_2p spectrum. The reaction order and the rate constant for degradation of dye have been determined to be first dimension and 1.6084×10^-4s. Due to the high bonding strength between TiO₂ film, and the substrate and the high specific surface area, the anodized TiO₂ can be used as efficient photocatalyst with high reactivity for waste water treatment and water purification.
