Fig. 4: The impact of temperature toward the C2+ product.

a Schematic diagram of elevated temperature promotion of CO2RR on the surface of Cu2O/PTFE, Cu2O/PTFE/Ag, and Pd-Cu2O/PTFE. b Corresponding FEs at different current densities on Cu2O/PTFE/Ag at 298 K and 348 K in 1.0 M KOH electrolyte (pH = 13.7 ± 0.1, 0.62 ± 0.03 Ω). c Product distributions and corresponding FEs at different current densities on Pd-Cu2O/PTFE at 348 K in 1.0 M KOH electrolyte. d Product distributions and corresponding FEs at different current densities on Pd-Cu2O/PTFE/Ag at 348 K in 1.0 M KOH electrolyte. e FEs and C2+/C1 ratio at −200 mA cm-2 on CP (Cu2O/PTFE), CPA (Cu2O/PTFE/Ag), PCP (Pd-Cu2O/PTFE), and PCPA (Pd-Cu2O/PTFE/Ag) at 298 K and 348 K. f Corresponding potentials and CEEs at different current densities on Pd-Cu2O/PTFE/Ag at 298 K and 348 K in 1.0 M KOH electrolyte. g Comparison of some typical results at −200 mA cm-2 at 348 K. All error bars represent the standard deviation calculated from at least 3 data points. All reported potentials were not IR corrected. Source data are provided as a Source Data file.
