Exceptional performance of hierarchical Ni-Fe oxyhydroxide@NiFe alloy nanowire array electrocatalysts for large current density water splitting

Water electrolysis represents a promising sustainable hydrogen production technology. However, in practical application which requires extremely large current densities (>500 mA cm −2 ), the oxygen evolution reaction (OER) becomes unstable and kinetically sluggish, which is a major hurdle to larg...
