A “Two‐Pronged” Strategy to Boost Hydrogen Evolution Kinetics on NiFe‐Based (Oxy)hydroxides via Oxygen Deficient Ni‐Mo‐Fe Coordinate Structures for Ultra‐Stable Ampere‐Level Alkaline Overall Water Splitting

NiFe (oxy)hydroxides have been regarded as one of the state-of-the-art catalysts for oxygen evolution reaction (OER). Unfortunately, the sluggish hydrogen evolution reaction (HER) kinetics limit its application as bifunctional electrocatalyst for alkaline overall water splitting (OWS). Herein, a "two-pronged" strategy is proposed to construct highly active oxygen deficient Ni-Mo-Fe coordinate structures in NiFe (oxy)hydroxide (NFM-OV
