Note:
The overarching goal of the proposed project is to develop metal hydrides that can be dehydrogenated and recharged at relatively low temperatures and pressures. The research objectives are: ยท To fabricate nanoscale magnesium boride powders with various B/Mg atomic ratios using mechanically-activated self-propagating high-temperature synthesis (MASHS). To investigate the effect of B/Mg atomic ratio on the hydrogenation and dehydrogenation properties of the obtained magnesium borides. Magnesium boride powders with various B/Mg atomic ratios will be fabricated from magnesium and boron powders by mechanically-activated self-propagating high-temperature synthesis (MASHS). The mechanical activation of the initial reactants will be conducted by ball milling in an argon environment. The activated mixtures will compacted into cylindrical pellets and ignited in a closed chamber filled with argon. The combustion products will be crashed to powders and characterized by X-ray diffraction (XRD) analysis, Brunauer-Emmett-Teller (BET) surface area analysis, laser diffraction particle size analysis, and scanning electron microscopy (SEM). The hydrogenation of the obtained powders will first be studied by high-pressure differential scanning calorimetry. Next, the hydrogenation and dehydrogenation properties of the obtained materials will be studied using pressure-composition-temperature (PCT) measurements and high-pressure hydrogenation at Sandia National Laboratories. The proposed project will complement the research conducted at the Hydrogen Materials - Advanced Research Consortium (HyMARC) in the area of advanced metal hydrides for hydrogen storage. It is expected that a synergistic effect of combining the PI's experience in the combustion synthesis of advanced materials with the comprehensive instrumentation capabilities of the HyMARC researchers will result in a remarkable progress in the development of metal hydrides with superior hydrogenation and dehydrogenation properties.
