The separation of butanes and butenes using MOF-74 (with two reticular MOFs with different pore sizes, Ni-IRMOF-74-I and Ni-IRMOF-74-II) was evaluated computationally using density functional theory. We identified that C alkene alkane selectivity stems from π-d chemical interactions, whereas selectivity differences among butenes stem from steric implications.
使用密度泛函理论对采用MOF-74(具有两种不同孔径的网状金属有机框架,Ni-IRMOF-74-I和Ni-IRMOF-74-II)分离丁烷和丁烯进行了计算评估。我们发现,碳碳双键/碳碳单键选择性源于π-d化学相互作用,而丁烯之间的选择性差异则源于空间效应。
