Electrochemical carbon dioxide reduction reaction (CO2RR) to yield multicarbon (C2+) products still suffers from a great hardship, which requires high current density and Faradaic efficiency (FE) accompanied by favorable stability for the purpose of industrial applications. Herein, we display 5.6 atom % Ag/Cu2O–Cu catalyst with abundant steady Ag/Cu+/Cu0 interfaces efficient conversion CO2-to-C2+ at ampere level density. attains desirable FE 76.5 ± 1.2% toward C2+ 1.0 A/cm2 in 1 M KOH electrolyte remains stable CO2 electrolysis 0.50 20 h using flow cell apparatus.

Electrochemical CO2 reduction to multicarbon products is vital for renewable fuels. While copper catalysts are effective C2+ production, the instability of Cu+ species hinders long-term performance. The present study reports development a Cu2O-PdO heterojunction and investigates influence an unoccupied orbital energy level regulation strategy on stabilization interfacial crystalline Cu2O during reaction (CO2RR). hybrid catalyst showed significant improvement, with 84% higher Faradaic efficiency C2H4, lasted over 7 h, vastly outperforming 2 h benchmark Cu2O. In-situ Raman, ex-situ XRD, theoretical calculations reveal that broadened d-orbital in PdO provides lower electrons, which contributes adjacent ions, high active interface significantly lowers barrier CO-CO dimerization step (2*CO → *OCCO) enhances selectivity activity CO2RR ethylene.

Abstract Electrocatalytic carbon dioxide reduction reaction (CO 2 RR) into high‐value products on Cu‐based catalysts holds promise for achieving neutrality. However, the productivity toward multi‐carbon in CO RR is insufficient practical applications owing to limited * dimerization process, especially under high current operation. Here, Ag‐doped oxide‐derived Cu nanosheets (CuAg x% NSs) are reported via tailoring Ag NSs at an atomic‐level form C 2+ products. The CuAg 0.123% achieved a significant Faradaic efficiency of 77.5% and 71.3% 300 500 mA cm −2 , respectively. Theoretical calculations situ characterizations reveal that single‐atomic facet generates asymmetric CO‐adsorbed sites, stabilizing adsorption further triggering C─C coupling This work emphasizes significance sites fine regulation critical intermediate enhance *CO
