Figure 5: Faradaic selectivities of the main CO2RR products.
From: Highly selective plasma-activated copper catalysts for carbon dioxide reduction to ethylene
Data were acquired after 60 min of CO2 electrolysis at a constant potential in CO2 saturated 0.1 M KHCO3. (a) CO, (b) formate, (c) CH4 (d) C2H4. Solid lines are guides for the eye. The remaining selectivity is due to H2, which is shown in Supplementary Fig. 8.
