Fig. 6: Effect of halogenation time on the performance of the catalysts for CO2 reduction reaction.

FEs of the products from electrochemical CO2RR are shown versus the amount of time the Cu foils were subjected to anodic halogenation in KCl (a), KBr (b), and KI (c). d–f FEs of H2, C1, C2, and C3 products from the same results shown in the corresponding upper plot. Data were acquired during 40 min of electrochemical CO2RR at a constant potential of ~ −1.11 V vs. RHE in 0.1 M KHCO3 saturated with CO2. Data legends apply to all plots in the same row. Source data are provided as a Source data file.
