Abstract

Novel porous aromatic frameworks, PAF-18-OH and its lithiated derivative PAF-18-OLi, have been successfully synthesized. In particular, PAF-18-OLi displays significant enhancement of H₂ and CO₂ adsorption capacity, especially for CO₂ uptake (14.4 wt%). More valuably, the stable PAF-18-OLi material exhibits high CO₂/N₂ selectivity, as high as 129 in the case of CO₂ capture from simulated post-combustion flue gas mixtures (85% N₂ and 15% CO₂). Furthermore, the PAF-18-OLi has shown improved H₂ storage capacity after lithiation.
