Nitrogen doped NiS2 nanoarrays with enhanced electrocatalytic activity for water oxidation†
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.
