Strain-optimized copper dual-atom sites for selective electroreduction of carbon dioxide to ethylene.

ABSTRACT: Electrocatalytic carbon dioxide (CO₂) reduction holds the great potential to convert excess emissions of carbon footprint into high value-added chemicals, but its activity, selectivity, stability, and reproducibility are still far away from satisfactory. The molecular catalysts with precise structures are unique platform to decipher the electrocatalytic mechanism, but they usually suffer from low performance. Herein, we report a strain-optimized dual copper complex immobilized in mesoporous carbon, which exhibits remarkable ethylene (C₂H₄) Faradaic efficiency (FE) up to 49.9% along with a multicarbon (C₂₊) product's FE up to 65.2% at -1.19 volts versus reversible hydrogen electrode. Concurrently, the catalyst displays considerable stability for 1
