Abstract

In this study, mesoporous Cu and N co-doped TiO2 crystals were synthesized with Cu and N co-doped titania xerogel by solvothermal treatment in different alcohols and the characteristics of Cu and N co-doped TiO2 were investigated with XRD, SEM, UV-vis and N2 sorption analysis. Results indicated that different alcohols facilitated formation and stability of pure anatase phase. The photocatalytic activity of samples was evaluated by the photocatalytic oxidation of acetone under visible light.The extraordinary photocatalytic performance of the Cu and N co-doped TiO2 crystals were synthesized with titania xerogel by solvothermal treatment in ethyl alcohol. This enhanced photoactivity is related to the bandgap narrowing, good dispersibility, the smaller pores and the larger specific area.
