Hydrothermal synthesis of CdS/functionalized graphene sheets nanocomposites

•CdS/FGS nanocomposites were prepared in a one-step hydrothermal synthesis route.•The different products have been controlled through experimental conditions.•The synthetic approach was simple for synthesis of other FGS nanocomposites.

CdS/Functionalized Graphene Sheets (CdS/FGSs) nanocomposites were successfully prepared in a one-step hydrothermal synthesis route. The morphology, structure characterization, and crystal structure of the as-prepared nanocomposites were performed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Through controlled experimental conditions, such as cadmium source and sulfide source, the different morphologies and dimensions of the final products have been controlled. The synthetic approach was simple and fast, and it may be extended for the synthesis of other FGS–metal-sulfide nanocomposites. By combining the unique properties of FGS and CdS nanoparticles, the strategy presented in this study is expected to be useful to prepare highly efficient graphene-based hybrids for potential applications in various fields.
