We describe the synthesis of MeH2N–BH2Me (3) and H3N–BH2Me (4) as potential hydrogen storage materials with 6.8 wt-% and 8.9 wt-% capacity, respectively. Compounds 3 and 4 readily release 2 equivalents of H2 at 80°C in the presence of a CoCl2 catalyst to furnish the corresponding trimerized borazine derivatives. Regeneration of 3 from its spent fuel material can be accomplished using a simple two-step process: activation with formic acid followed by reduction with LiAlH4.

In this paper, graphite and Fe2O3 are introduced into MgH2 powder by the method of hydrogenation after magnetic grinding. Hydrogen storage materials which composite of MgH2–5 wt.% C and MgH2–5 wt.% C–5 wt.% Fe2O3 are successfully prepared. The physical structure of these materials was analyzed and characterized by XRD, SEM, etc. Furthermore, the influence of graphite and Fe2O3 on the hydrolysis of MgH2 was systematically investigated. The results show that MgH2–C–Fe2O3 composite powder has the fastest hydrogen release rate in municipal drinking water and the highest conversion rate. Graphite and Fe2O3 can effectively reduce the activation energy of the hydrolysis reaction of MgH2 and improve the hydrolysis kinetics of MgH2. The synergistic effect of the coaddition of graphite and Fe2O3 can significantly increase the hydrolysis conversion rate of MgH2 and improve the hydrolysis kinetics.
