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

Figure 3. Investigation of reaction mechanism. (A) PXRD patterns of Cu-based catalysts with and without IL modification after CORR; (B) Comparison of Cu LMM spectra of Cu₂O/CuO-IL before and after CORR; (C) Comparison of B 1s spectra of IL-modified Cu-based catalysts after CORR; In situ Raman spectra of (D) Cu and (E) Cu₂O/CuO-IL during CORR at various potentials; (F) Time-resolved in situ Raman spectra of Cu₂O/CuO-IL during CORR; (G) Optimized models of Cu(111) and CuBO₂(001); (H) Reaction free energies for the formation of C₂₊ alcohols on Cu and CuBO₂. PXRD: Powder X-ray diffraction; IL: ionic liquid; CORR: CO reduction reaction; LMM: one type of Auger electron peak; OCP: open circuit potential.
