    • Abstract

       

      This study aims to develop the graphene oxide-based metal sulphide nanocomposite, which has outstanding photocatalytic properties. The graphene oxide (GO) was prepared by the Hummers method, and GO/nickel sulphide (GO/NiS) nanocomposite was synthesized by the hydrothermal method to evaluate the photocatalytic dye degradation. The synthesized nanocomposites were characterized by X-ray diffraction, Fourier transform infrared, ultraviolet–visible,scanning electron microscopy with energy-dispersive X-ray and transmission electron microscopy techniques. Photocatalytic dye degradation efficiency of GO, NiS and GO/NiS nanocomposites were evaluated by using crystal violet (CV)dye. The GO/NiS nanocomposite exhibited good photocatalytic activity as compared to NiS as well as GO. The optimum condition obtained for the effective photocatalytic degradation of CV is pH $=$ 8.0, crystal violet $=$ $2.0 \times 10^{-5}$ M, nanocomposite $=$ 0.30 g. The rate of degradation of CV with the composite was found to be $2.39\times 10^{-4}$ s$^{-1}$.
