Unveiling the In Situ Dissolution and Polymerization of Mo in Ni4Mo Alloy for Promoting the Hydrogen Evolution Reaction
Abstract
NiMo alloys are efficient electrocatalysts in alkaline water electrolyzer for the hydrogen evolution reaction (HER). Metals are usually considered to be stable during the cathodic process. However, the actual behaviors of Mo in the NiMo alloys are unexplored. Here, we present the instability of Mo in the Ni 4 Mo alloy as a highly efficient HER electrocatalyst in an alkaline medium. Mo in Ni 4 Mo is oxidized and dissolved in the form of MoO 42− first. The dissolved MoO 42− will re‐adsorb on the electrode surface and polymerize. Theoretical calculations indicate that the adsorption of the dimer Mo 2 O 72− can promote the HER activity of metal Ni. The addition of MoO 42− to the electrolyte can not only repair the durability of Ni 4 Mo alloy, but also facilitate the HER activity of pure metal of Ni, Fe, and Co. Our findings provide insight into the structural transformation mechanism and performance‐enhanced origin of cathodic materials under the reaction conditions.

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.
