摘要: Visible-light photocatalytic activity of metal-doped TiO2 films prepared by dipcoating method was investigated. Cu, Fe, and Al atoms were doped in the they exist as their oxide nearly stoichiometric matrices. It is found that Cu doping effective for visible-light photocatalysis films, while Fe- Al-doped hardly shows activity. The optical absorption spectra non-doped show band gap narrowing observed Cu-doped films. Recombination photogenerated electron/hole pairs takes place quickly Fe-doped film, charge separation effectively film. into film has effect on
