Abstract

Hydrazine oxidation‐assisted water splitting is a critical technology to tackle the high energy consumption in large‐scale H 2 production. Ru‐based electrocatalysts hold promise for synergetic hydrogen reduction (HER) and hydrazine oxidation (HzOR) catalysis but are hindered by excessive superficial adsorption of reactant intermediate. Herein, this work designs Ru cluster anchoring on NiFe‐LDH (denoted as Ru c /NiFe‐LDH), which effectively enhances the intermediate adsorption capacity of Ru by constructing Ru─O─Ni/Fe bridges. Notably, it achieves an industrial current density of 1 A cm −2 at an unprecedentedly low voltage of 0.43 V, saving 3.94 kWh m −3 H2 in energy, and exhibits remarkable stability over 120 h at a high current density of 5 A cm −2 . Advanced characterizations and theoretical calculation reveal that the presence of Ru─O─Ni/Fe bridges widens the d‐band width (W d ) of the Ru cluster, leading to a lower d‐band center and higher electron occupation on antibonding orbitals, thereby facilitating moderate adsorption energy and enhanced catalytic activity of Ru.

  • Metal Ru has a high charge density, leading to excessive adsorption of reaction intermediates during the HER and ORR.

    “metal Ru has a high charge density, leading to excessive adsorption of reaction intermediates during the HER and ORR.”

    From Interface strain engineering of a Ru–RuO x /graphene aerogel composite boosts HER, OER and ORR applications (2026) · cites this paper as [16]

    The Introduction (page not provided) describes excessive adsorption of hydrazine on Ru and attributes it to strong coupling between N 2p and Ru d orbitals. The Results and Discussion (page not provided) also describe overly strong hydrogen adsorption for a Ru surface during HER. The paper does not attribute this behavior to high charge density or address adsorption during ORR; its oxidation reaction is hydrazine oxidation (HzOR). (LLM, conf=0.88)

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.
