Paper Title:
Photocatalytic Properties of Anodic TiO2 Nanotubes
  Abstract

The anodic titania nanotubular films for photocatalyst were synthesized by anodic oxidation in HF electrolyte, and the photocatalytic properties of anodic TiO2 layer were investigated. The self organized anodic TiO2 film consisting of nanotubes with diameter of 100-150 nm as photocatalyst can be obtained by electrochemical method at a constant potential of 20 V for 40 min in HF solution. In order to improve the photocatalytic efficiency the anodic titania nanotube was heat treated at 550oC for 1h. In the evaluation of dye degradation, heat treated catalyst shows much higher efficiency than non-heat treated one.
