Preparation, Characterization and Photocatalytic Activity of TiO_2 Nanotubes with Different Morphologies

【摘要】:正 TiO2 nanotubes with different morphologies were prepared by a simple hydrothermal method and then treated with HCl. The as-prepared TiO2 nanotubes were characterized with XRD, BET, SEM, TEM, HRTEM and XPS. The photocatalytic activity of the samples was evaluated by the photocatalytic oxidation of acetone in the gaseous phase and the photocatalytic decolorization of methyl orange solution in the aqueous phase, respectively. It was found that
