Fig. 5: Performance and benefit of bipolar C2H4 electrosynthesis system.
a Schematic of a bipolar C2H4 electrosynthesis system by pairing CO2 reduction and PA decarboxylation. b FEC2H4 and JC2H4 over W-CuOx for cathodic CO2 reduction under different current densities in a continuous-flow cell. c Stability test of W-CuOx over 100 h in 1.0 M KOH (pH = 14.0 ± 0.2) for CO2 reduction at a current density of −400 mA cm−2. d FEC2H4 over W-CuOx for CO2 reduction and np-Pt for PA decarboxylation under different current densities or voltages with 85% iR correction in a paired continuous-flow cell. e C2H4 production comparison of our paired electrosynthesis system with reported traditional CO2 reduction electrolyzers. f Stability test of the paired electrosynthesis system over 265 h at a current of 400 mA cm−2. g TEA of bipolar C2H4 production in the paired electrosynthesis system at different current densities. Error bars represent the standard deviation of three independent samples. Data are presented as mean values ± standard deviation. Source data are provided as a Source data file.
