From: Electrocatalytic CO reduction to multi-carbon alcohols on functional ionic liquid-incorporated Cu-based electrodes

Figure 2. CO electroreduction performance. (A) Linear sweep voltammetry curves; (B) FEs of all CORR products at different potentials over pure Cu and Cu₂O/CuO-IL catalysts [Error bars represent SD from three independent replicates (n = 3 per group; rectangle filled with lines: Cu catalyst; solid-filled rectangle: Cu₂O/CuO-IL catalyst)]; (C) FEs_{C2+ alcohols} and partial current densities for C₂₊ alcohols; (D) C_dl plots; (E) Nyquist plots of Cu-based catalysts with and without IL modification; (F) Stability for CORR over the Cu₂O/CuO-IL catalyst. FEs: Faradaic efficiencies; CORR: CO reduction reaction; IL: ionic liquid; SD: standard deviation; RHE: reversible hydrogen electrode.
