In this talk, I will discuss results from our group in the area of computational modeling using density functional theory for reversible hydrogen storage materials. The reversible hydrogen storage is an important area in the context of renewable energy and the reversibility places important challenge. We have studied doped magnesium hydrides as well as decorated metal organic frameworks (MOF). ...
Vanadium-doped magnesium nanostructures are fabricated by an oblique angle co-deposition method and hydrogenated/dehydrogenated for 21 cycles. The effective thermal conductivity and density of the MgH2 nanostructures is measured by using a photothermal system. A multilayer physical model is used to fit the experimental data. Our results show that the effective thermal conductivity of the hydrog...
Doping with additives in a Li-Mg-N-H system has been regarded as one of the most effective methods of improving hydrogen storage properties. In this paper, we prepared Li3AlH6 and evaluated its effect on the dehydrogenation properties of 2LiNH2-MgH2. Our studies show that doping with Li3AlH6 could effectively lower the dehydrogenation temperatures and increase the hydrogen content of 2LiNH2-MgH...
Magnesium and its alloys are the most investigated materials for solid-state hydrogen storage in form of metal hydrides, but there still unresolved problems with kinetics thermodynamics hydrogenation dehydrogenation this group materials. Severe plastic deformation (SPD) methods, such as equal-channel angular pressing (ECAP), high-pressure torsion (HPT), intensive rolling, fast forging, have bee...
