Abstract

Two effective methods, 1) substitution of M elements and 2) preparation of appropriate mixtures, for decreasing the dehydriding temperatures of M-N-H and M-B-H (M=Li, Mg) systems were briefly reviewed. The dehydriding reactions of LiNH₂ and LiBH₄ with/without Mg substitutions proved that the dehydriding temperatures become lower with the increasing Mg concentrations. Also, a mixture of Mg(NH₂)₂ and LiH, which was chosen as one of the best compositions with low dehydriding temperature among mixtures of M(NH₂)_x and MH_y. Increasing the LiH ratio in the mixtures is one of the important techniques to prevent ammonia release. Moreover, the dehydriding temperature of LiBH₄ was reduced by 150 K by mixing 2 M of LiNH₂, suggests that the stabilities of the dehydriding reactions of complex hydrides can be controlled by introducing new pathways by mixing.
