Ultrahigh Carbon Dioxide-Selective Composite Membrane Containing a γ-CD-MOF Layer.

Mixed matrix membranes (MMMs) for CO separation have overcome the trade-off between gas permeability and gas selectivity to some extent. However, most MMMs still are prepared in lab- and pilot-scales since the permeability and selectivity of CO are not good enough to reach the economically available requirements. Moreover, the fabrication of few MMMs with good separation performance is time-consuming or need harsh conditions.
