The preparation of high-performance polycrystalline MOF membranes for MeOH/MTBE separation poses a challenge. In this study, intact 400 nm thick UiO-66 membranes with well-controlled structures were successfully fabricated using a novel formulation. The high ligand/metal ratios and the new zirconium sources provide ideas for designing UiO-66 membranes with effective pore structures. Consequently, the membranes exhibited an exceptional pervaporation performance, achieving a flux of 5.68 kg m⁻² h⁻¹ and a separation factor of 28000 for MeOH/MTBE (5/95 wt/wt.%) at 40 °C. Further, the UiO-66 membranes have excellent temperature and concentration resistance and remain stable during 120 h of operation. The high pervaporation performance, along with this stability, demonstrates that this UiO-66 membrane is a competitive candidate for MeOH/MTBE separation.

用于 MeOH/MTBE 分离的高性能多晶 MOF膜的制备提出了挑战。在这项研究中，使用一种新颖的配方成功地制造了具有良好控制结构的完整的 400 nm 厚的 UiO-66 膜。高配体/金属比和新的锆源为设计具有有效孔结构的UiO-66膜提供了思路。^{因此，该膜表现出优异的渗透蒸发性能，在40℃下对于MeOH/MTBE (5/95 wt/wt.%)实现了5.68 kg m -2}  h ^-1的通量和28000的分离因子。此外，UiO-66膜具有优异的耐温性和耐浓度性，并且在120小时的运行过程中保持稳定。高渗透蒸发性能以及稳定性表明，这种 UiO-66 膜是 MeOH/MTBE 分离的有力候选膜。
