The electrochemical CO2 reduction reaction (CO2RR) is ideally a route to close the atmospheric CO2 cycle by utilizing fossil fuel emissions. The technical goal is the electrochemical conversion of carbon dioxide to fuels (such as CH4, CH3OH, C2H6), hydrogen storage (such as HCOOH), or precursors for further utilization (such as CO or C2H4). CO2RR is most generally performed in a bicarbonate buffer to maximize CO2 solubility and to mitigate water reduction. However the buffer limits the kinetics of the OER reaction on the anode. Glycerol has been used to reduce the overall cell potential for CO2RR in alkaline electrolysis systems. BPMs have been used in CO2RR to stimulate local HCO3 --to-CO2 conversion near the cathode in zero-gap electrolytic systems and to decouple the anolyte from the catholyte in an photoelectrochemical CO2RR integrated system. CO2RR and GEOR have been combined to reduce cell potentials for sustained CO2 electrolysis at high current densities (Ecell ≈ 3.9 V at 175 mA cm -2 on an Au electrocatalyst) in a flow reactor. To our knowledge, the sustained pairing of CO2RR and GEOR have not been characterized at the low cell potentials of interest to PEC integrated systems, for example.
