Unexpected behavior of ethylene adsorption in metal-organic framework CPO-54

Open metal sites are strong adsorption sites in metal-organic frameworks. Sorption experiments show that the enthalpy of adsorption of ethylene on the materials investigated herein does not follow the trend observed typically for other adsorptives with similar strength of interaction. The experiment’s aim is to investigate the structural response of the MOFs upon exposure to ethylene and compare it to other relevant adsorptives.
