One general method was developed for the synthesis of graphene-metal sulphide nanoplates,including graphene/ZnS nanoplates,graphene/CdS nanoplates and graphene-CuS nanoplates.As a concept proof,the graphene/ZnS nanoplates were selected as the model to characterize their morphology and phase by scanning electron microscopy (SEM),transmission electron microscopy (TEM),X-ray diffraction pattern (XRD),raman spectroscopy and X-ray photoelectron spectroscopy (XPS).And their photocatalytic activity was tested.This method demonstrated a general approach towards the fabrication of graphene-metal sulphides nanoplates as promising for the photocatalytic fields.
