| 英文摘要 | layered metal-organic frameworks would be a diverse source of crystalline sheets with nanometer thickness for molecular sieving if they could be exfoliated, but there is a challenge in retaining the morphological and structural integrity. we report the preparation of 1-nanometer-thick sheets with large lateral area and high crystallinity from layered mofs. they are used as building blocks for ultrathin molecular sieve membranes, which achieve hydrogen gas (h-2) permeance of up to several thousand gas permeation units (gpus) with h-2/co2 selectivity greater than 200. we found an unusual proportional relationship between h-2 permeance and h-2 selectivity for the membranes, and achieved a simultaneous increase in both permeance and selectivity by suppressing lamellar stacking of the nanosheets. |
