Ni2P Aerogels with Pt Single-Atom Doping Tune Competitive Adsorption for Boosted Methanol Electrooxidation

Abstract

Methanol oxidation reaction (MOR) provides an effective method to attain high-value-added chemicals. Nevertheless, the competitive adsorption between CH 3 OH and OH – causes poor activity and selectivity. In this work, Ni 2 P aerogels decorated with single-atom Pt are designed to tune the adsorption behavior of CH 3 OH and OH –, achieving an unprecedented current density of 2848.3 A g cat –1 and a Faradaic efficiency of 93.3% for formic acid. A series of electrochemical tests, operando spectroscopic characterizations, and theoretical calculations verify that Pt single-atom doping not only accelerates the adsorption of CH 3 OH and realizes high coverage of CH 3 OH on Ni active sites to impede the OER, but it also decreases the barrier of the rate-determining step, achieving a high-efficiency MOR. Specifically, an underlying competitive adsorption mechanism between CH 3 OH and OH – to enhance MOR is proposed. This work is highly instructive for developing promising and efficient electrocatalysts at the atomic scale and contributing to a deeper understanding of the MOR mechanism.

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.
