Parameterization and quantification of two key operando physio-chemical descriptors for water-assisted electro-catalytic organic oxidation.

ABSTRACT: Electro-selective-oxidation using water as a green oxygen source demonstrates promising potential towards efficient and sustainable chemical upgrading. However, surface micro-kinetics regarding co-adsorption and reaction between organic and oxygen intermediates remain unclear. Here we systematically study the electro-oxidation of aldehydes, alcohols, and amines on Co/Ni-oxyhydroxides with multiple characterizations. Utilizing Fourier transformed alternating current voltammetry (FTacV) measurements, we show the identification and quantification of two key operando parameters (ΔI_harmonics/I_OER and ΔV_harmonics) that can be fundamentally linked to the altered surface coverage ( ΔθOH*/θOH*OER ) and the changes in adsorption energy of vital oxygenated intermediat
