Nitrogen-Induced Deep Reconstruction and Formation High-Valent Nickel Species γ-NiOOH Surface Layer on NiFealloy/NiFeN Pre-catalysts for the Efficient Water Oxidation

Transition metal-based electrocatalysts undergo electrochemical surface reconstruction to generate metal oxy-hydroxide-based hybrids, which regard the actual active sites for the oxygen evolution reaction (OER). Many efforts have been devoted to...
