Imidazolium-based ionic liquids have led to enhanced CO2 electroreduction activity due cation effects at the cathode surface, stabilizing reaction intermediates and decreasing activation energy. In aqueous media, alkali cations are also known improve reduction on metals such as Ag, with enhancement attributed electrical double layer trending size of cation. However, effect a mixed catholyte solution in presence an imidazolium-based liquid has not been well-explored. Herein, 1-ethyl-3-methylimidazolium tetrafluoroborate, [EMIM][BF4], water was investigated salts unravel interaction for Ag. Although both [EMIM]+ individually improved CO conversion Ag water, electrochemical results showed that hindered imidazolium-mediated most conditions. Li+, particular, sharply inhibitory compared other strongly redirected selectivity hydrogen evolution. The nature inhibition spectroscopic techniques, including situ surface-enhanced Raman spectroscopy (SERS) dynamic impedance (DEIS). Along computational insights from density functional theory (DFT), data suggest inhibit [EMIM]-mediated by competing surface adsorption sites, preventing potential-dependent structural reorientation imidazolium, promoting evolution bringing solvated surface.
