Membrane-based separation has the merit of low carbon footprint. In this study, the pore size of metal-organic framework (MOF) membranes is rationally designed for discriminating various pairs of hydrocarbon isomers. Specifically, Zr-MOF UiO-66 (UiO stands for University of Oslo) membranes are developed for separating p/o-xylene due to their proper pore size. For n-hexane/2-methylpentane separation, the functional groups and proportion of the ligands in UiO-66 are gradually adjusted to effectively regulate the pore size, and UiO-66-33Br membranes are constructed. In addition, relying on the utilization of ligands with shorter length, MOF-801 membranes with smaller pore size are fabricated for n/i-butane separation.
基于膜的分离具有低碳足迹的优点。在本研究中，合理设计金属有机框架（MOF）膜的孔径以区分各种烃类异构体对。具体而言，由于其合适的孔径，开发了Zr-MOF UiO-66（UiO代表奥斯陆大学）膜用于分离对二甲苯/邻二甲苯。对于正己烷/2-甲基戊烷的分离，逐渐调整UiO-66中配体的官能团和比例以有效调节孔径，并构建了UiO-66-33Br膜。此外，依靠使用较短长度的配体，制备了孔径较小的MOF-801膜用于分离正丁烷/异丁烷。
