Preparation of Cu2O-TiO2 Nanocomposite in Ethylene Glycol System and its Photocatalytic Activity under Visible Light Irradiation

Article Preview

Abstract:

The nano-scale Cu2O-TiO2 couple oxide photocatalyst was successfully synthesized by the homogeneous hydrolysation, followed by the solvothermal crystallization and ethylene glycol-thermal reduction process, respectively. The obtained photocatalysts were characterized by X-ray diffraction (XRD), showing that the crystal phase composition and the crystal size of the prepared photocatalyst were affected by the ethylene glycol-thermal reduction temperature. The photocatalytic activity of Cu2O-TiO2 was also evaluated by the degradation of methyl orange (MO) as a model compound. The results showed that the prepared Cu2O-TiO2 exhibited higher photocatalytic activity for the decomposition of MO than the pure Cu2O and the commercial Degussa P25 TiO2 under visible light irradiation.
