CO2 Capture: Specific K+ Binding Sites as CO2 Traps in a Porous MOF for Enhanced CO2 Selective Sorption (Small 22/2019)

In article number 1900426, Ze Chang, Xian-He Bu, and co-workers demonstrate a new strategy for the immobilization of alkali metal cations (K+) in metal–organic frameworks (MOFs) toward gas affinity boosting. The immobilized K+ cations could be desolvated and serve as traps for CO2 capture, which effectively enhances the CO2 sorption performances of the MOFs.
