Operando SERS for CO2RR over the Cu2O/PTFE catalyst at different applied potentials in 1.0 M KOH electrolyte (pH = 13.7 ± 0.1, 1.2 ± 0.1 Ω) at a 298 K and b 348 K. Operando SERS for CO2RR over the Pd-Cu2O/PTFE catalyst at different applied potentials at c 298 K and d 348 K. e The *CO adsorption free energy and *H adsorption free energy on Cu2O and Cu2O/Pd at 298 K and 348 K. All reported potentials were not IR corrected. f Energy profiles of asymmetric coupling of *CO with *COH on Cu2O and Cu2O/Pd surfaces with different CO coverages. g Energy profiles of asymmetric CO-COH coupling on Cu2O and Cu2O/Pd surfaces at 298 K and 348 K.
