Fig. 2: Electrochemical CO reduction performances.

a Linear sweep voltammetry curves of Cu-SA/Ti3C2Tx measured in CO- or Ar-saturated 1 M KOH solution at a scan rate of 10 mV s−1; potentials have been iR-corrected. b, c Faradaic efficiencies (FE) toward H2 and CO reduction products (C2H4, EtOH, and acetate) of b Cu-SA/Ti3C2Tx and c Cu-NP/Ti3C2Tx at various applied potentials for 2 h. d The partial current densities (jp) of C2H4 and EtOH at test potentials. e Chronoamperometry test and FE of C2H4 for Cu-SA/Ti3C2Tx at an applied constant potential of –0.7 V vs RHE for 68 h. The error bars correspond to the standard deviations of measurements over three separately prepared samples under the same testing conditions.
