Visible Light Photoreduction Properties of N-Doped TiO₂ Nanostructured Films

Abstract:

N-doped TiO2 nanostructured composite (TiO2-N) films with excellent photocatalytic performance under visible light were successfully formed on glass and stainless steel substrates by spin-coating process. The photoreduction performance of as-prepared coatings was characterization by reduction of Ag+ and measurement of photovoltaic response. It was found that Ag+ can be easily reduced to metallic Ag and obvious photocurrent and photovoltage were observed by V-I recording under visible light irradiation. Crystalline structure, nitrogen states in the lattice, composition and surface morphology of the nanostructured films were analyzed by XRD, XPS and SEM.
