Lewis basic site (LBS)-functionalized zeolite-like supramolecular assemblies (ZSAs) with high CO2 uptake performance and highly selective CO2/CH4 separation

ZSA-7, ZSA-8, and ZSA-9 have been hydrothermally synthesized by utilizing the functional modification strategy. ZSA-7 and ZSA-8 possess high CO2 adsorption abilities and outstanding selectivity separation for CO2 over CH4.
