CO2 reduction reaction (CO2RR) systems are the heart of many proposed e-refinery schemes. There have been few studies on the separation systems that will be needed to complement CO2RR reactors. Here, we show that by strategic use of downstream separations and recycling of unreacted CO2, the efficiency of CO2RR can be significantly improved without changes in the electrochemical reactor.
