Effect of Particle Shape and Electrolyte Cation on CO Adsorption to Copper Oxide Nanoparticle Electrocatalysts

Abstract: Cu2O-derived nanoparticles are efficient catalysts for the electrochemical conversion of CO and CO2 to multicarbon products. Generation of multicarbon products requires dimerization of adsorbed CO, which is accelerated when the coverage of CO is high. The electrolyte cation and the initially exposed crystal plane of the catalyst both affect the reaction rate, but the relation between these effects and CO coverage is unclear, especially given the surface reconstruction that occurs during reduction reactions on … Show more

“…The reactants on the electrode also interact with the liquid side of the reaction environment. Solvent composition (33)(34)(35)(36), the identity and concentration of the supporting electrolyte's anions (37)(38)(39) and cations (39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51), and the pH of the electrolyte (52)(53)(54)(55)(56)(57)(58) can greatly impact the product selectivity. For example, the rate of ethylene evolution during CO2 reduction was found to increase by a factor of ≈15 when switching from Li + -to Cs + -containing electrolyte (47).…”

“…The peak is rather asymmetric, and the (negative) intensity increases at more negative potentials, likely due to increasing electric repulsions, inducing carbonate desorption 108 . Further examination of Figure 2 reveals a clear shift in wavenumber from 1517 to 1508 cm -1 , a trend which was also observed in previous studies 103,108 . To further probe this behavior, the starting position of the band as a function of initially applied potential was studied and the obtained frequency (wavenumber) at which the peak minimizes at 0.04 mV more negative potential (spectra not shown) is presented in Figure 4.…”

“…Alternatively, the combination of a low surface coverage with CO and a superior production of ethylene could be explained by an enhanced stimulated rate of CO dimerization in a perchlorate environment, although the origin of this phenomenon is not yet fully understood. 53 …”
