▎ 摘　　要

In the present study, nickel sulfide (NiS) decorated reduced graphene oxide was synthesized by a facile one-step hydrothermal approach. Characterization of the as-made nanohybrid using a Field emission scanning electron microscope (FE-SEM) and powder X-ray diffraction (XRD) clearly demonstrate the successful attachment of NiS onto the rGO nanosheets. Further, the prepared NiS-rGO nanohybrid has been examined for the electrochemical nonenzymatic detection of glucose using cyclic voltammetry, linear sweep voltammetry and amperometry. The electrochemical studies demonstrated that the NiS-rGO nanohybrid modified electrode detects glucose linearly over a concentration range of 5.0 x 10(-5) to 1.7 x 10(-3) M with a detection limit of 1.0 x 10(-5) M. The obtained detection limit for the NiS-rGO nanohybrid is very much comparable to the recent literature values. Further, the NiS-rGO nanohybrid modified electrode showed an excellent anti-interference ability against electroactive species and showed good reproducibility and stability.
