Visible Light Photoreduction Properties of N-doped TiO2 Nanostructured Films

摘要：

　　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.
