Abstract
Disclosed herein are compositions for olefin adsorption comprising a trimeric [Ag—R]3 compound that undergoes a reversible transformation to trimeric [Ag-R·(alkene)]3 and/or dimeric [Ag-R·(alkene)]2. The reversible transformation allows one to break adsorbent design trade-offs and achieve low heat of adsorption while retaining high selectivity and uptake. Additionally disclosed is a method to separate alkenes from a mixture.
