a SEM and HAADF-STEM (inset) image of the catalyst. b Linear sweep voltammetric curves in Ar-saturated and C2H2-saturated solution. The scanning rate is 10 mV s−1. c Comparison in the geometric current density of ethylene (\({j}_{{{{{{{\rm{C}}}}}}}_{2}{{{{{{\rm{H}}}}}}}_{4}}\)) over the Cu microparticles (MPs) loaded on pristine carbon papers (Cu/CP) and carbon papers coated with the microporous gas diffusion layer (Cu/GDL-CP). d FEs of the E-HAE products and the current densities at different potentials. Error bars correspond to the standard deviation. e Comparison in the FE and the geometric current density for ethylene production from E-HAE over different catalysts, which were tested in this work. All experiments were conducted in 1 M KOH solution at 25 °C. Source data are provided as a Source Data file.
