Abstract:

Ag/AgNO3 modified titanate nanotubes films were prepared by hydrothermal method and followed by photo-reduction method. The morphology, structure and composition of the product were characterized. The film exhibited high photocatalytic actibity and photochromic property. Ag/AgNO3 acted as the active center and generated·O-2, HO2· and ·OH. These strong oxidative free radicals not only degraded the organic matter, but also eliminated bacterium. Ag/AgNO3 modified titanate nanotubes films would be a promising material in various of application areas in virtue of its excellent photocatalytic activity, photochromic property and antibacterial activity.

Key words: Titanate nanotubes film, Ag/AgNO3, Photocatalytic activity, Photochromic property, Antibacterial activity
