Abstract

Degussa P25 was utilized to synthesize TiO2 nanorods and nanowires via a simple hydrothermal method to enhance the photocatalytic activities for various applications. The FESEM results verify the production of different structures of TiO2. Samples treated at lower and higher temperature display cylindrical and cuboid morphologies respectively. UV/Vis was employed to determine the band gap of produced products. Samples treated at lower temperature display direct band gap unlike the sample treated at higher temperature displaying similar characteristic as P25. The results indicate that manipulating the structure of Degussa P25 via alkaline hydrothermal treatment may alter the photocatalytic activities of TiO2.
