Figure 3

(a) Experimentally measured and (b) simulated cathode surface concentrations of CO2(aq) as a function of phosphate buffer concentration and current density. (c) Experimentally measured changes in CO2 concentration near the electrode surface as a function of potential. All solutions are composed of equimolar H2PO4 and HPO42– mixtures. CO2 concentrations are normalized to initial equilibrium concentrations.
