The electrochemical CO2 reduction reaction (CO2RR) to produce multicarbon (C2+) hydrocarbons or oxygenate compounds is a promising route obtain renewable fuel valuable chemicals; however, producing C2+ at high current densities still challenge. Herein, we design hierarchically structured tandem catalysis electrode for greatly improved catalytic activity and selectivity products. constructed of sputtered Ag nanoparticle layer on hydrophobic polytetrafluoroethylene (PTFE) membrane nitrogen-doped carbon (NC)-modified Cu nanowire arrays. arrays are in situ grown PTFE by oxidation CuAl alloy, which the chemical etching metal Al induces formation array structure. Within hierarchical configuration, CO can be efficiently generated an active then spillover transfer NC-modified layer, Cu/NC interfaces enhance *CO trapping adsorption. During CO2RR, optimized achieves superior Faradaic efficiencies 53.5% 87.5% ethylene (C2H4) products density 519.0 mA cm–2, respectively, with C2+/C1 ratio 10.42 long-term stability up 50 h. In Raman attenuated total reflection-surface enhanced infrared absorption spectroscopy (ATR-SEIRAS) confirm that Ag–Cu–NC system significantly enhances linear adsorption intermediates dissociation H2O, improves C–C coupling capability, stabilizes key intermediate *OCCOH
