Figure 1. Schematic illustration of various pathways for CO₂ valorization from industrial flue gas. Path I represents the direct flue-gas electrolysis in gas-fed electrolyzers without capture steps. Path II illustrates a sequential route for CO₂ capture and electrolysis, with electrolysis also carried out in a gas-fed electrolyzer. Path III depicts the alternate route in which captured CO₂ is directly converted via electrolysis of the captured CO₂ solution, while the regenerated absorbent is reused for subsequent CO₂ capture. Path IV shows the concerted route for simultaneous CO₂ capture and electrolysis reported in this work.
