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.
