Graphene-based nanocomposites are emerging as a new class of materials for many applications. In this study, we report the growth mechnism of graphene oxide/zinc oxide composites with type and concentration of zinc precursor. The rods and flowers of zinc oxide were grown on graphene oxide sheet at 90 °C in 1 hour without employing any catalysts. The structure, morphology and optical properties of as synthesized composites were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy, and UV–vis absorbance spectroscopy. The XRD pattern demonstrated the formation of graphene decorated by hexagonal ZnO with high crystallinity. FESEM image showed that the sheet like graphene decorated with ZnO in homogeneously. The characteristic absorbance peaks of graphene/ZnO nanocomposites were observed in UV visible spectra. |
