Confinement of Ag(I) Sites within MIL-101 for Robust Ethylene/Ethane Separation

Effective utilization of Ag(I) π-complexation adsorbents for practical C2H4/C2H6 separation urges both good separating performances and high stabilities. In this work, we incorporated AgNO3 onto a typical metal–organic framework (MOF) of MIL-101 to obtain efficient Ag(I) π-complexation adsorbents. It was found that the separation performances were highly dependent on the location of the AgNO3, which could be at the interior or the exterior of...
