In this study, graphene/ zinc oxide nanocomposite was prepared via a chemical functionalization method by using graphene oxide (GO) as a precursor of graphene and Zn(NH3)4CO3 as a precursor of zinc oxide. Thermogravimetric analysis, X-ray diffraction (XRD), fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM) were used to characterize crystal structure and morphology of the functionalized graphene sheets FGS/ZnO nanocomposites. It was shown that the well-dispersed ZnO nanoparticles were deposited on FGS homogeneously. The composites exhibited photocatalytic activity efficiently under low-power ultraviolet (UV) light. This facile and low-cost method makes the composite a perfect candidate in applications of catalysis and other areas.
