Abstract
The anodic oxidation method has been used to prepare thin films of titanium dioxide (TiO2) in acid and alkaline electrolytes. The influence of pH on the structure, the morphology and the photo response of the deposited TiO2 has been evaluated by measuring the current density. The experimental results showed that the photo current response was pH dependent. The acid electrolytes being the best medium in producing stable oxide films with good adhesion to titanium metal substrate and good charging rate and current density.
