The solar-driven conversion of atmospheric CO2 was further investigated. Direct air capture (DAC) of CO2 and its conversion into value-added products is a promising technology to afford an overall negative carbon footprint when conversion is done with a renewable energy source such as sunlight. Moreover, DAC technologies can be easily decentralized to desired locations, opposed to capture from concentrated point sources requiring proximity to emissions. The direct capture and conversion of aerobic CO2 is especially challenging due to the ultra-low concentration, requiring aggressive capturing agents for suitable kinetics and consequently higher thermodynamic input for chemical reduction. We performed the atmospheric CO2 capture by pumping indoor air through capture solutions (1 M aqueous TEA or glycolic NaOH) at 1.8 L min -1 flowrate for 2 days using an aquarium pump (Figure ). The TEA/H2O solution captured only 0.02±0.01 mol CO2 per mol TEA after this time due to slow capture kinetics. In contrast, capture efficiency of the NaOH/EG solution was notable reaching 0.73±0.07 mol of captured CO2 per mol NaOH (Figures ).
