Comparison of the Photocatalytic Efficience for Cu and N Co-Doped TiO2 by Sol-Gel and Xerogel-Hydrothermal Methods

In this study, mesoporous Cu and N doped TiO2 crystals were synthesized with Cu and N doped titania by xerogel-hydrothermal treatment and sol-gel treatment. The characteristics of Cu and N doped TiO2 were investigated with XRD, UV-vis, XPS and N2 sorption analysis. The photocatalytic activity of samples was evaluated by the photocatalytic oxidation of acetone under ultraviolet light. The photocatalytic activity of the xerogel-hydrothermal modified Cu and N doped TiO2 was considerably higher than that of the sol-gel modified Cu and N doped TiO2. This enhanced photoactivity is related to the smaller particle sizes, bicrystalline, the smaller pores and the larger specific area.
