This work demonstrates capture and direct solar-driven utilization of CO2 to syngas, in combination with plastic-derived waste oxidation, in a two-compartment PEC setup. CO2 is captured from a concentrated stream or simulated flue gas or air in amine/hydroxide solution, and directly converted over a PVK|CoPcNH2@MWCNT photocathode under 1 sun irradiation. A Ni foam|Cu26Pd74 alloy anode completes the circuit by catalyzing EG oxidation to GA selectively. Replacing thermodynamically challenging water oxidation with EG oxidation allows the system to operate with a single light absorber without any externally applied voltage. Realworld plastic waste can be directly used as EG source after alkaline pre-treatment, facilitating waste valorization. Utilizing air as the CO2 source, pre-treated waste plastics as electron donors, and sunlight as the energy source, this proof-of-concept CO2 capture and solar-driven utilization system could be promising for future decentralized off-the-grid scalable solar fuels and chemical synthesis.
