Abstract Exploring an efficient nonnoble metal catalyst for hydrogen evolution reaction (HER) is critical industrial alkaline water electrolysis. However, it remains a great challenge due to the additional energy required H─OH bond cleavage and lack of enough H 2 O adsorption sites most catalysts. Herein, integration oxophilic Eu 3 with NiCo alloy evoked multisite synergism facilitate dissociation HER proposed. The optimized ‐NiCo exhibits excellent activity low overpotential only 60 mV at 10 mA cm −2 good electrochemical stability, which superior that ‐free comparable benchmark Pt/C. key roles on enhanced performance are identified by in situ Raman spectroscopy theoretical calculations. It discovered strong oxophilicity facilitates breakage bonding while evoking electron redistribution /NiCo interface accelerating Volmer step HER. Furthermore, obtained as both anode cathode displays overall water‐splitting stability 1.0 M KOH solution. believed this study provides important inspiration design high‐performance electrocatalysts toward based rare‐earth materials.
