Well matched: Submicrometer-sized metal–organic framework (MOF) crystals (ZIF-90) were synthesized by a nonsolvent-induced crystallization technique and incorporated in mixed-matrix gas-separation membranes. ZIF-90/6FDA-DAM membranes (empty pink circle; beyond the upper bound for polymer membranes) show unprecedented high performance for CO2/CH4 separation by a MOF-based membrane. The key is the combination of the highly selective MOF and a highly permeable polymer.
