-Sorbents for direct air capture of CO2 using moisture swing

Technologies to remove CO2 from ambient air, or “direct air capture” (DAC), have recently demonstrated that they can contribute to “negative carbon emission.” we developed a new humidity-swing absorbent based on PO43–/HPO42–/H2PO4– ions exhibiting superior CO2 absorption capacity and kinetics compared to that of CO32–/HCO3–-based absorbent.
