Crystalline Phase and Photocatalysis Activity of Electrochemically Anodized Titania Nanotubes
- Titania (TiO2) nanotubes were developed by electrochemical anodization method. The crystalline phase of TiO2 nanotubes annealed at different temperatures was identified by X-ray diffraction. Anatase phase TiO2 started revealing at 300 ºC and pronounced at 500 ºC indicating the better crystallinity of TiO2 nanotubes. Photocatalysis activity of TiO2 nanotubes in methylene blue solution was also examined under UV light irradiation. High temperature annealed TiO2 nanotubes improved the photodegradation of methylene blue in aqueous solution.
