In conclusion, our study shows the potential of photo-swing CO2 capture using aminopolymer-based contactors enhanced by cost-effective plasmonic TiN and low-power LEDs. Notably, our findings reveal that even with illumination on just one side of the contactor, the photo-swing method achieves comparable CO2 desorption levels to traditional thermally driven processes. This exceptional desorption capacity is likely attributed to the localized heating facilitated by plasmonically activated TiN, coupled with its high thermal conductivity, releasing >99% of adsorbed CO2 in 5 min. Moreover, our extensive cycling experiment, spanning >90 cycles, underscores the remarkable stability of the TiN light absorber and the photothermal durability of the aminopolymer indicating the long-term resilience of these materials in the photo-swing CO2 capture process. Compared to existing and emerging DAC technologies, photo-swing DAC paves a way towards a fast process with reduced thermal energy penalties. To accurately assess the true potential of this lab-scale technology as a cost-and energy-competitive DAC solution, we recommend the development of a dedicated sorbent architecture able to maximize the interaction of light with the photoresponsive material and optimize operating conditions, including light type and applied optical power, to enhance photon-to-desorbed-CO2 efficiencies.
