Experimental and Modeling Study of Gas Adsorption of Gas Molecule in Metal Organic Framework and Zeolite

摘要

Metal Organic Frameworks (MOF) are 1, 2 or 3-dimensional polymers consisting of metal ions attached to organic ligands. Zeolites are inorganic crystalline structures with multidimensional channel systems. They are made up of tetrahedrally organized molecules which are bound to oxygen atoms. Both MOFs and zeolites are rapidly gaining popularity and significance due to their structural diversity and porosity. The porosity acts as attractive sites for emission gases such as CO_2 or N_2 to be adsorbed onto their surface. In this work, MIL-101 (Cr), a chromium-based MOF, and Zeolite 13X and 5A are synthesized. MOF is intended to be coated on 3D printed PETG substrates. The gas adsorption properties of Zeolite is studied both experimentally and using atomistic simulation. The calculated physisorption isotherm shows the similar trend of experimental data. The work provides foundation to coat 3D printed components with MOF and Zeolite coatings and use them for emission control and gas storage applications.
