“…Currently, metal–organic frameworks (MOFs) in which metal nodes and organic linkers can be assembled to provide varying pore sizes, crystal structures, and surface functionalities, are promising candidate materials for CO 2 removal from industrial flue gas streams. , Of the MOFs that have been reported, Calgary Framework 20 (CALF-20) is particularly appealing, as this MOF has a high capacity and selectivity for CO 2 over both N 2 and H 2 O. ,− CALF-20 has also shown to satisfy some of the practical elements needed to facilitate industrial deployment of solid adsorbents for CO 2 capture. For example, CALF-20 is synthesized from commercially available components in an industrially scalable reaction, and it is chemically resistant to steam and oxidation, which is appealing for regeneration purposes due to readily available steam and hot air in industrial settings. , …”
