Fig. 3: Faradic efficiency values of the gaseous products generated during the EC CO₂RR.

Chronopotentiometries (CPs) were conducted at constant currents of I = −20 mA, I = −10 mA, I = −5 mA, with the different ILs. Set-up: H-cell; WE: Ag foil; catholyte: 0.3 M IL in ACN; CE: Ni mesh; anolyte: 0.1 M KOH.
