【 摘 要 】

tsPair electrosynthesis of formate was achieved by combining CO2 reduction reaction (CO2RR) and formaldehyde oxidation reaction (FOR) in the membrane electrode assembly.Replacing oxygen evolution reaction with thermodynamically more favorable FOR reduces energy consumption.CO2RR//FOR exhibits excellent electrochemical performance (100 mA cm−2 @ 0.86 V), electricity consumption normalized by the mass of formate was 0.413 Wh g−1.
