Optimizing the Volmer Step by Single-Layer Nickel Hydroxide Nanosheets in Hydrogen Evolution Reaction of Platinum
Abstract
Hydrogen is considered by many to be a promising energy currency, particularly for the transportation sector and for mobile devices. To realize a hydrogen-based fuel economy, hydrogen must be produced in an efficient and sustainable manner. In this article, single-layer nickel hydroxide (Ni(OH) 2 )-nanosheet-assisted Pt/C catalysis for the hydrogen evolution reaction (HER) in an alkaline environment was investigated. The HER activity trajectories of the hybrid catalysts in correlation with the composition and morphology of Ni(OH) 2 were explored in depth. By optimizing the Volmer step through addition of single-layer Ni(OH) 2 into Pt/C catalysis, this hybrid catalyst manifests a 110% increase of the HER activity by using only 20 wt % single-layer Ni(OH) 2 with a lithium ion additive as compared to the state-of-the-art Pt/C catalyst. Density functional theory calculations revealed that the single-layer Ni(OH) 2 behaves superior in adsorption ability of OH – when compared with multilayer Ni(OH) 2 . The single-layer Ni(OH) 2 contributes to dual improvement on both the Volmer step and the adsorption of OH – during HER.

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.
