| Abstract: | Titanium dioxide nano thin film has been emphasized for its excellent photocatalytic activity. Herein, titanium dioxide nano thin film was prepared on ITO surface by anodic deposition. The effect of anodic current density and deposition time on structure and adhesion of titanium dioxide nano thin film obtained was investigated. Surface morphology and structure of the nano thin film were analyzed by means of SEM and XRD. Photocatalytic activity and hydrophilicity thereof were studied as well. The results show that titanium dioxide nano thin film is composed of nano particles with nano holes among them, which is transparent to visible light with wave length of 400 to 700 nanometers, and has excellent photocatalytic activity and hydrophilicity. |
