Electrochemical co-upgrading CO2 and glycerol for selective formate production with 190% overall Faradaic efficiency (IMAGE)
Caption
To reduce energy consumption and enhance the economic viability of CO2 electrolysis systems, replacing the anodic oxygen evolution reaction (OER) with the glycerol oxidation reaction (GOR) has emerged as a promising approach. To achieve highly selective formate production at both the cathode and anode, an efficient GOR//CO2RR paired electrolysis system has been developed using NiOOH@Ni3S2/NF and defect-rich bismuth nanosheets as catalysts. Under a high current density of 160 mA cm-2, the system achieves a state-of-the-art total formate Faradaic efficiency of ca. 190%, offering a novel strategy for the co-upgrading of CO2 and biomass.
