| Outline of Final Research Achievements |
Highly crystalline TiO2 mesoporous films were prepared by anodizing in a hot glycerol electrolyte containing phosphates without post-annealing at more than 450℃. Applied potential during anodizing became more precise by using the three electrode system. The formation rate of the anodic film was increased by increasing basicity of the electrolyte. The small amount of phosphate species containing the anodic films induced crystallization of the film during the anodizing. In addition, highly crystalline anodic films can be obtained by anodizing in the lower basic electrolyte containing phosphates at high applied voltage more than 20 V.
