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.
