Abstract

Despite the fundamental and practical significance of the hydrogen evolution and oxidation reactions (HER/HOR), their kinetics in base remain unclear. Herein, we show that the alkaline HER/HOR kinetics can be unified by the catalytic roles of the adsorbed hydroxyl (OH ad )-water-alkali metal cation (AM + ) adducts, on the basis of the observations that enriching the OH ad abundance via surface Ni benefits the HER/HOR; increasing the AM + concentration only promotes the HER, while varying the identity of AM + affects both HER/HOR. The presence of OH ad -(H 2 O) x -AM + in the double-layer region facilitates the OH ad removal into the bulk, forming OH – -(H 2 O) x -AM + as per the hard–soft acid–base theory, thereby selectively promoting the HER. It can be detrimental to the HOR as per the bifunctional mechanism, as the AM + destabilizes the OH ad, which is further supported by the CO oxidation results. This new notion may be important for alkaline electrochemistry.

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.
