Immobilization of Ag(i) into a metal–organic framework with –SO3H sites for highly selective olefin–paraffin separation at room temperature†
Abstract
Introduction of Ag(I) ions into a sulfonic acid functionalized MOF ((Cr)-MIL-101-SO3H) significantly enhances its interactions with olefin double bonds, leading to its much higher selectivities for the separation of C2H4–C2H6 and C3H6–C3H8 at room temperature over the original (Cr)-MIL-101-SO3H and other adsorbents at room temperature.
