NiS2 Nanoparticles Grown on Reduced Graphene Oxide Co-Doped with Sulfur and Nitrogen for Enhanced Hydrogen Evolution Reaction in Acid Media
JOURNAL OF THE ELECTROCHEMICAL SOCIETY(2022)
Abstract
NiS2 nanoparticle electrocatalysts grown on sulfur and nitrogen co-doped reduced graphene oxide (NiS2/S,N-rGO) were explored. Since the hybrid catalyst of NiS2/S,N-rGO had a large surface area and high conductivity, it demonstrated outstanding electrocatalytic properties. This NiS2/S,N-rGO hybrid electrocatalyst required only 95 mV overvoltage to reach the current density of 10 mA cm(-2) in hydrogen evolution reaction (HER) in acidic solution. In addition, the 5000 cycles test experiment showed the excellent HER electrochemical stability of the NiS2/S,N-rGO catalyst. This work also provided new strategies for increasing the catalytic activity of non-precious metal electrocatalysts.
