Here, the fabrication of a defect-free membrane that is based on a zeolite-like metal-organic framework (ZMOF) with the underlying ana topology is reported. The unique ana-ZMOF structure provides high degree of pore connectivity, which is reflected by the fast transport of gases. Prominently, it offers an optimum pore-aperture size, affording notable sieving selectivity for butane/isobutane, and optimal pore energetics for reverse CO /H separation. This emphasize the potential for the application of pure MOF membranes, paving the way to more sustainability of energy resources.
在此，报道了基于具有底层ana拓扑结构的类沸石金属有机框架（ZMOF）制备无缺陷膜。独特的ana-ZMOF结构提供了高度的孔隙连通性，这通过气体的快速传输得以体现。显著的是，它提供了最佳的孔径尺寸，对丁烷/异丁烷具有显著的筛分选择性，并且对CO/H逆向分离具有最佳的孔隙能量学。这突出了纯MOF膜应用的潜力，为能源资源的更可持续性铺平了道路。
