Abstract

We presented the fabrication of N doped NiS₂ nanoarrays using NH₃·H₂O as the dopant precursor for the electrocatalytic OER. N doping primarily affects the configuration of electrons and the density of d-states near the Fermi level, together with the adsorption of the OER intermediate, thus overcoming the intrinsic limits of reaction kinetics.
