CuO/TiO2 nanocrystals grown on graphene as visible-light responsive photocatalytic hybrid materials

[摘要] CuO/TiO2 nanocrystals grown on graphene (CuO/TiO2–GR) were prepared by a simple hydrothermal method using Cu(CH3COO)2.H2O and (NH4)2TiF6 as precursors and graphene oxide (GO) as templates. The asprepared composites were characterizated by TEM, XRD, FT–IR to determine composition and phase purity. The photocatalytic activity of the samples was evaluated by photo-degradation of methylene blue (MB) aqueous solution under UV and visible light illumination. This work may provide new insights into preparing other inorganic graphene-based composites.
