Novel lithium-loaded porous aromatic framework for efficient CO2 and H2 uptake
MetadataShow full item record
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.
