Foreign cation-promoted active species formation enables efficient electrochemical glycerol valorization

Abstract

The foreign cation substitution approach to Ni–Co spinel oxide promotes the active NiOOH species formation, resulting in remarkable electrochemical glycerol oxidation activity and selectivity for formate production. The generated NiOOH improves both the indirect GOR and the coadsorption capacity of OH* and glycerol, which is crucial to the potential-dependent GOR mechanism.
