Figure 3. (A) Schematic illustration of a concerted CO₂ capture and conversion system; (B-E) Efficiency of the concerted system using 2 M MEA to capture CO₂ from a flue gas containing 15% CO₂/80% N₂/5% O₂ and performing electrolysis of the CO₂-capturing MEA at 50 mA·cm^-2 for 24 h: (B) concentration of CO₂ leaving the concerted system ([CO₂]_outlet); (C) FE for CO and H₂; (D) cumulative volume of gaseous products; (E) CO₂ capture efficiency. The shaded region in Figure 3B shows the CO₂ concentration change in the outlet gas stream during 12 h CO₂ capture from a simulated flue gas (15% CO₂/80% N₂/5% O₂) using 2 M MEA. MEA: Monoethanolamine; FE: Faraday efficiencies.
