To improve the hydrogen storage performance, Mg(3)La alloy and TiCl(3) is ball milled simultaneously with LiBH(4) to yield a designed composition. It has been revealed that there is a synergistic effect of Mg(3)La alloy and TiCl(3) on the dehydrogenation of LiBH(4), which improves the dehydrogenation performance when compared to adding either hydrogenated Mg(3)La or TiCl(3) alone. 4.3 wt% of H(2) can be released within 10 min at 400 degrees C in the LiBH(4) + Mg(3)La + TiCl(3) system. The dehydrogenation activation energy of this system is 52.6 kJ mol(-1), which is much lower than that of pristine LiBH(4). In addition, the LiBH(4) + Mg(3)La + TiCl(3) system preserves fast dehydrogenation kinetics and stable hydrogen storage capacity in the re-/dehydrogenation cycles.
