Abstract

Anatase TiO₂ nanotube film was prepared by calcination of the orthorhombic titanic acid nanotube at 400 °C. To expand the light absorption, AgBr nanoparticles were sensitized on TiO₂ film. The AgBr–TiO₂ nanotube film showed a high activity for MO photo-degradation under visible light irradiation. Moreover, the photocatalytic activity was further improved a lot after annealing of the AgBr–TiO₂ nanotube film.
