CuNi Aerogels with Suppressed Water Activation for Efficient Nucleophilic Methanol Electrooxidation

Qie Fang,
Shushan Ye,
Lirong Zheng
et al.

Abstract: Suppressing the competitive oxygen evolution reaction (OER) is the critical prerequisite for efficient nucleophile oxidation in electrochemical biomass upgrading coupled with hydrogen production. Herein, Cu91Ni9 aerogels with atomically dispersed Ni are designed as effective nucleophile electrooxidation catalysts with significantly suppressed water activation performance, exhibiting a remarkable 99.3% Faradaic efficiency in the conversion of methanol to formic acid. Experimental and theoretical investigations … Show more

“…This is mainly due to the electrostatic adsorption of OH – on the anode with the increased potential . Besides, two ascending absorption peaks at about 1650 and 1228 cm –1 are detected, assigned to the adsorbed H 2 O and *OOH intermediates, respectively . The vibration frequency of H 2 O and *OOH species in CoFe LDH shifts toward a high wavenumber (1656 and 1232 cm –1 ).…”
