Study of Photocatalytic Activity of TiO₂ Nanotube Derived from Different Anodized Parameters

Abstract:

In this study titanium dioxide nanotube (TNT) were prepared by anodization method. The effects of the temperature, time and voltage on the anodization process were investigated in detail. Photocatalytic activity of the TNT films was evaluated in terms of the degradation of methylene blue in aqueous solution under UV light irradiation. The results showed that the optimization of temperature, voltage and time on anodization process were 45oC, 20 V and 1 day, respectively. Consequently, these results indicate that the optimization of anodization process is critical to achieve the high performance of photocatalytic reaction.
