title: Photocatalytic properties of titanate nanotube powders prepared by alkaline hydrothermal method.
abstract: This paper reports the photocatalytic activities of titanate nanotubes (TNTs) synthesized using different methods and compares them with that of P25. Rhodamine B was selected as the organic compound to be decomposed by the microwave/UV/photocatalyst hybrid process. The as-prepared TNT had titanate crystalline structure, whereas the TNT calcined at 723 K was phase-transformed into anatase structure. When the as-prepared TNT was ion-exchanged using HCl, Na+ content was reduced from 8.36 wt% to 0.03 wt%. The ion-exchanged TNT showed the highest photocatalytic activity among the TNTs tested in this study, but it was lower than that of P25.
