Metal-organic framework (MOF) glasses have demonstrated great potential for high-performance separation. Herein a uniform hybrid MOF glass membrane was fabricated by using the liquid state of ZIF-62 to facilitate the melting of ZIF-8. The doping of ZIF-8 enhanced both the adsorption capacity as well as the ideal C3H6/C3H8 selectivity of ZIF-62 glass. As expected, the hybrid glass membrane exhibited good C3H6/C3H8 separation performance while preserving the CO2 performance of the sole ZIF-62 membrane.
