Abstract
With increasing demand for green and clean energy, the research community moves toward electrocatalytic hydrogen production. Herein, we synthesized the reduced graphene oxide decorated-cobalt disulfide (rGO-CoS2) nanocomposites via the one-step facile hydrothermal method and investigated their excellent hydrogen evolution reaction (HER) activities. The rGO-CoS2 nanocomposites showed an aggregated structure of spherical CoS2 nanoparticles interconnected along with GO nanosheets. The rGO-CoS2 nanocomposites exhibited a low overpotential of 377 mV and a small Tafel slope of 121 mV/dec. This work delivers a prospective scheme for developing the high efficient rGO-CoS2 electrocatalysts for future green energy technology in hydrogen production.
