interaction and achieve efficient ethylene purification from the mixture of hydrocarbon gases. The high performance of UPC‐612 and UPC‐613 for C2H2/C2H4/C2H6 separation has been verified by gas sorption isotherms, density functional theory (DFT), and experimentally determined breakthrough curves. This work provides a one‐step separation of the ternary gas mixture and can further serve as a blueprint
在常温常压下,从乙烷(C 2 H 6),乙烯(C 2 H 4)和乙炔(C 2 H 2)的混合物中分离乙烯(C 2 H 4)是一项重大挑战。由于这些分子的相似分子大小和动力学直径,其筛分作用无能为力。我们报告了一种基于稳定的ftw拓扑Zr-MOF平台(MOF-525)的新修改方法。引入环戊二烯钴官能团导致了新型ftw型MOFs材料(UPC‐612和UPC‐613),增加了主客体的相互作用并实现了从碳氢化合物气体混合物中高效乙烯的纯化。UPC‐612和UPC‐613在C 2 H 2 / C 2 H 4 / C 2 H 6分离方面的高性能已通过气体吸附等温线,密度泛函理论(DFT)和实验确定的穿透曲线得到了验证。这项工作提供了三元气体混合物的一步分离,并且可以进一步用作设计和构造此类应用的功能导向多孔结构的蓝图。
