This further supports the notion that there is a silver-specific inner-sphere process occurring, with the desorption process from the double layer around the electrode accounting for the observed differences in the reduction potentials across cations.
electrode material is likely to be the source of the lower peak potentials
hese shifts suggest that the formation of a complex through the π–π interaction of the imidazolium cation with the carbon dioxide intermediate is probably unlikely to be the cause of the reduction occurring at a lower overpotential.
This likely involves the cation binding to the silver surface first, where a desorption process, allowing the CO2 molecule to access the electrode surface, precedes an irreversible reduction of the carbon dioxide, as clarified in (B) of Figure 6.
