Enhanced Stability

In this work, the possibility of creating a polymer-based adaptive scaffold for improving the hydrogen storage properties of the system 2LiH+MgB2+7.5(3TiCl3·AlCl3) was studied. Because of its chemical stability toward the hydrogen storage material, poly(4-methyl-1-pentene) or in-short TPXTM was chosen as the candidate for the scaffolding structure. The composite system was obtained after ball milling of 2LiH+MgB2+7.5(3TiCl3·AlCl3) and a solution of TPXTM in cyclohexane. The investigations carried out over the span of ten hydrogenation/de-hydrogenation cycles indicate that the material containing TPXTM possesses a higher degree of hydrogen storage stability.

Storage Properties

The Na decorated BN sheets have a stable sandwich structure and can be regarded as an excellent hydrogen storage material. With respect to first-principles calculation, the electronic structure, geometric structure, partial density of states, mulliken population and ability of absorbing hydrogen molecules of the Na decorated BN sheet have been investigated. The results show that: (1) The most stable structure is Na atom adsorption on the top of N atom, it has the greatest binding energy. (2) Na decorated BN sheet can adsorb twelve H2 molecules and the average adsorption energy is 0.530 eV/H2. (3) The hydrogen storage rate of Na decorated BN sheet is about 8.943wt%. (4) The adsorbed H2 molecules have polarization phenomenon.

Storage Properties

Magnesium is an attractive hydrogen storage candidate due to its high gravimetric and volumetric storage capacities (7.6 wt.% and 110 gH2/l, respectively). Unfortunately, its use as a storage material for hydrogen is hampered by the high stability of its hydride, its high dissociation temperature of 573–673 K and its slow reaction kinetics. In order to overcome those drawbacks, an important advancement toward controlling the enthalpy and desorption temperatures of nano-structured MgH2 thin films via stress/strain and size effects is presented in this paper, as the effect of the nano-structuring of the bulk added to a biaxial strain on the hydrogen storage properties has not been previously investigated. Our results show that the formation heat and decomposition temperature correlate with the thin film’s thickness and strain/stress effects. The instability created by decreasing the thickness of MgH2 thin films combined with the stress/strain effects induce a significant enhancement in the hydrogen storage properties of MgH2.
