Abstract
Electrochemical CO2 reduction reaction (CO2RR) to multicarbon (C2+) products holds immense significance in promoting a closed carbon cycle and solving global energy problems, but it faces challenges of unsatisfactory selectivity. In this work, we constructed an Ag single-atom alloy cascade catalyst (AgCu-SAA) using an epoxide gelation approach, which enhanced the utilization efficiency of the CO intermediate through an inter-migration pathway. As a result, the C2+ products’ Faradaic efficiency (FE) of 83.4% was achieved at a current density of 900 mA cm–2. Moreover, the FE of the C2+ products remained as high as 74.8% even at a high current density of 1100 mA cm–2. In situ Raman spectra and density functional…
