The present disclosure relates to a MEA electrolyser comprising a cathodic compartment operating CO2 reduction reactions (CORR) of COfrom a gaseous CO-containing stream, an anodic compartment operating all-liquid organic oxidation reactions (OOR), an ionic exchange membrane in between. A CORR-OOR system can further include a gas-liquid separation unit in fluid communication with the anodic compartment to receive the anodic product mixture and separate gaseous COfrom the anodic product mixture to produce a CO-depleted liquid product stream and a recovered pure gaseous COstream. The system can further include a recycle line in fluid communication with the gas-liquid separation unit to redirect the recovered pure gaseous COstream to the cathodic compartment of the MEA electrolyser as a portion of the gaseous CO-containing stream. The present disclosure also concerns a process for electrochemically converting the gaseous CO-containing stream to multi-carbon products in such a MEA CORR-OOR electrolyser.

Electrosynthesis of oxirane can include contacting a halide electrolyte with an anode that includes an electrocatalyst comprising iridium oxide loaded with a period-6 metal oxide and provided on a metal substrate. The cathode can be operated under ORR conditions. The electrochemical system can also be provided as an integrated system that includes COelectroreduction to produce ethylene and formation of hypochlorous acid using the electrocatalyst, followed by contact of the ethylene and the hypochlorous acid to form ethylene chlorohydrin which is, in turn, contacted with OHions to produce oxirane.
