摘要：
TiO2-graphene (TiO2-RGO) nanocomposites were prepared via a simple chemical method by using graphene oxide (GO) and TiO2 nanoparticles as starting materials. The morphologies and structural properties of the as-prepared composites were characterized by X-ray diffraction, Raman spectroscopy, N-2 adsorption-desorptionmeasurements, and transmission electron microscopy. TiO2-RGO nanocomposites exhibited great photocatalytic activity toward reduction of CO2 into CH4 (2.10 mu mol g(-1) h(-1)) and CH3OH (2.20 mu mol g(-1) h(-1)), which is attributed to the synergistic effect between TiO2 and graphene.
