▎ 摘　　要

In this study, a facile and efficient strategy for preparing zinc sulfide-graphene nanosheets (ZnS/GNs) hybrid nanomaterials was assisted via a facile and efficient solvothermal method. Field emission gun scanning electron microscopy with energy-dispersive X-ray analysis, transmission electron microscopy, Fourier transform infrared spectrometer, X-ray photoelectron spectra were used. It was observed that the GNs were partially covered by ZnS homogeneous nanoballs. The electrochemical performances of ZnS/GNs hybrid nanomaterials as electrodes were measured and investigated by cyclic voltammetry and galvanostatic charge/discharge techniques. Results indicated that the introduction of GNs highly improved the electrocatalytic activity, durability, and stability of ZnS/GNs hybrid nanomaterials. Thus, the ZnS/GNs nanocomposites are expected to be an effective electrode materials.
