A series of copper sulfide nanocrystals/graphene nanocomposites (CuS/GR) with different weight ratios of GR were fabricated via a one-step hydrothermal approach by using dimethylsulfoxide (DMSO) as the source of sulfur and solvent. The as-prepared samples were studied by X-ray diffraction (XRD), UV-vis diffuse reflectance spectra (DRS), transmission scanning electron microscopy (TEM) and photoluminescence spectra (PL) are employed to determine the properties of the samples. The results show that the CuS nanocrystals with an average size of 16 nm almost overspread on the GR graphene scaffold. The samples exhibit excellent photocatalytic activities in degrading the methylene blue (MB) compared with pure CuS. This work shows that CuS/GR nanocomposites would be promising in dye wastewater treatment as Fenton-like reagents.
