Abstract Endowing materials with specific functions that are not readily available is always of great importance, but extremely challenging.

Abstract Although it is commonly believed that the water‐dissociation‐related Volmer process rate‐limiting step for alkaline hydrogen evolution reaction (HER) on Pt‐based catalysts, underlying essence, particularly atomic scale, still remains unclear. Herein, revealed sluggish water‐dissociation behavior probably stems from unfavorable orbital orientation and kinetic issue successfully resolved via N‐induced tuning. Impressively, N modified Pt–Ni nanowires deliver an ultralow overpotential...
