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 CH/CH selectivity of ZIF-62 glass. As expected, the hybrid glass membrane exhibited good CH/CH separation performance while preserving the CO performance of the sole ZIF-62 membrane.
金属有机框架（MOF）玻璃在高性能分离方面已展现出巨大潜力。在此，通过利用ZIF-62的液态促进ZIF-8的熔融，制备了一种均匀的混合MOF玻璃膜。ZIF-8的掺杂提高了ZIF-62玻璃的吸附容量以及理想的CH/CH选择性。正如预期的那样，混合玻璃膜在保持单一ZIF-62膜的CO性能的同时，展现出良好的CH/CH分离性能。
