摘要：

Anatase TiO2 nanotube film was prepared by calcination of the orthorhombic titanic acid nanotube at 400 degrees 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.
