摘要
The photocatalytically deposition of silver nanoparticles on titania films is studied by atomic force microscopy (AFM), UV-visible spectroscopy, and X-ray photoelectron spectroscopy (XPS). A simple method of making mesoporous TiO2 films consisting of monodispersed nanoparticles is presented. This films adsorb silver ions from aqueous silver salt. Ions yield silver nanoparticles by UV irradiation. The concentration of the nanoparticles on the film is influenced by the original concentration of silver salt in solution, indicating the large capacity of these films to adsorb silver ions.
