Bulk heating experiments in electrochemical CO2 reduction on copper have shown variable results. While all reports show increasing hydrogen and decreasing methane at elevated temperatures, ethylene promotion has varied between studies. We expect that this discrepancy may be due to variable convective mass transport between systems, which has been shown to have a significant effect on selectivity at 25 °C and would become especially important at elevated temperatures due to decreased CO2 solubility. There is evidence from the electrochemical sensor literature that enhanced reactivity can be achieved by using local heating. In the case of CO2 reduction, this would overcome the tradeoff associated with decreasing bulk CO2 solubility. Recently, this concept has been applied to CO2R catalysis with both surface heating and cooling, achieving altered performance without significantly affecting the bulk temperature. In these works, Bi rotating disk electrodes (RDEs) increased their activity for formate by a factor of 1.7 upon raising surface temperatures to 65 °C and planar Cu electrodes boosted their methane selectivity to 80% by cooling the electrode to -4.4 °C (and applying pulsed electrolysis). In contrast to previous works, surface heating on copper showed no clear trend in ethylene or methane Faradaic efficiencies with respect to temperature, especially in the absence of supporting EDTA in the electrolyte, supporting the fact that hydrodynamics can significantly impact performance. In this work, we evaluate how mass transport and electrodeposited organic films affect the performance of heated electrodes for ferricyanide and CO2 reduction to C2+ products.
