Engineering Metallic Heterostructure Based on Ni3N and 2M‐MoS2 for Alkaline Water Electrolysis with Industry‐Compatible Current Density and Stability
Abstract
Alkaline water electrolysis is commercially desirable to realize large‐scale hydrogen production. Although nonprecious catalysts exhibit high electrocatalytic activity at low current density (10–50 mA cm−2), it is still challenging to achieve industrially required current density over 500 mA cm−2 due to inefficient electron transport and competitive adsorption between hydroxyl and water. Herein, the authors design a novel metallic heterostructure based on nickel nitride and monoclinic molybdenum disulfide (Ni 3 N@2M‐MoS 2) for extraordinary water electrolysis. The Ni 3 N@2M‐MoS 2 composite with heterointerface provides two kinds of separated reaction sites to overcome the steric hindrance of competitive hydroxyl/water adsorption. The kinetically decoupled hydroxyl/water adsorption/dissociation and metallic conductivity of Ni 3 N@2M‐MoS 2 enable hydrogen production from Ni 3 N and oxygen evolution from the heterointerface at large current density. The metallic heterostructure is proved to be imperative for the stabilization and activation of Ni 3 N@2M‐MoS 2, which can efficiently regulate the active electronic states of Ni/N atoms around the Fermi‐level through the charge transfer between the active atoms of Ni 3 N and MoMo bonds of 2M‐MoS 2 to boost overall water splitting. The Ni 3 N@2M‐MoS 2 incorporated water electrolyzer requires ultralow cell voltage of 1.644 V@1000 mA cm−2 with ≈100% retention over 300 h, far exceeding the commercial Pt/C║RuO 2 (2.41 V@1000 mA cm−2, 100 h, 58.2%).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
