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.
