Main Focus

Metal-Organic Frameworks (MOFs) are crystalline porous compounds, consisting of metal ions linked together by organic bridging ligands, which possess very high sorption capacities and show a complex sorption behavior due to their large specific surface area and pore structure, respectively. These MOFs can be used for storage of gases such as hydrogen and methane, separation of isotopes such as hydrogen and deuterium, gas purification, sensors or catalysis. My current research is focusing on the potential of porous MOFs in the areas of gas storage and isotope separation of hydrogen at very low temperature. The physisorption and diffusion processes of hydrogen isotopes on MOFs will be analyzed by low-pressure volumetric measurements at very low temperatures. By this way, I shall develop in my thesis an understanding of the molecular behavior of sorption and the diffusion mechanism, including quantum effects at low temperatures, on below-nanometer-pore-size MOFs.
