In situ X-ray powder diffraction study of thermodynamics and kinetics of noble gas adsorption by novel metal organic framework

Metal-organic frameworks (MOFs) are porous hybrid materials combining metal ions (Mn+) with coordinative organic linkers. The main advantage of MOFs is related to their large chemical and structural diversity due to the quasi-infinite combination between metal ions/oxo-clusters and organic linkers, providing various types of structures and functionalities. This proposal is dedicated to the investigation of thermodynamics and kinetics of noble gas uptake by the novel porous MOF of Al2O(MDIP) (where MDIP is ethylenediisophthalate). Such system was selected due to its narrow 3-D pore structure, capable for effective capture and separation of Kr and Xe gas molecules. The monitoring of potential structural changes upon temperature/pressure/time-dependent adsorption in combination with the volumetric and theoretical studies is of a great importance for understanding the mechanisms of gas adsorption or/and separation particularly in Al2O(MDIP) and the other MOFs in general.
