a Potential profiles on Ag electrodes covered by polymer layers with ρp = 300 C·cm-3 (orange curve) and ρp = 0 (black curve) in 10 mM HOTf at −1.8 V vs SHE. Schematic of the rate determining step of CO2 reduction is shown. b Plots of the electric field strength in Stern layer based on the electrode potential. Solid curves: Ag electrodes covered by polymer layers with different ρp (unit: C·cm-3) in 10 mM HOTf. Gray dashed curve: Bare Ag electrode in 10 mM HOTf + 40 mM KOTf. Source data are provided as a Source Data file.
