Hydrogen bond interactions on a dual-core copper catalyst promote the activation of low-concentration CO 2 and the generation of ethylene

Key Points

• High faradaic efficiency for ethylene production was achieved through effective hydrogen bonding.
• The study evaluated a dual-core copper catalyst featuring OH− bridging ligands to enhance CO2 activation.
• Incorporation of binuclear copper coordination complexes boosted C–C coupling in the reaction environment.
• Implications hold for optimizing catalyst design in future carbon capture and conversion technologies.
