a Schematic diagram of Ni1-C/Cl@Cu2O NCs tandem electrocatalysis for C2H4 production. b FEC2H4s of Ni1-C/Cl@Cu2O tandem electrocatalysts and sole Cu2O electrocatalysts at different applied current densities. c jC2H4s of Ni1-C/Cl@Cu2O tandem electrocatalysts and sole Cu2O electrocatalysts at different applied current densities. d Calculated free energies for C2H4 formation on Cu (111) plane. e Calculated free energies for C2H4 formation on Cu (111)@NiC3Cl coupled site. The flow rate of CO2 inlet was 10 sccm. The measured resistance of the flow cell electrolyzer containing 0.05 M K2SO4 electrolyte was 4.37 ± 0.31 Ω. The error bars correspond to the standard deviations were acquired based on three independent experiments under the same testing conditions. Source data are provided as a Source data file.
