Hydrogen storage reaction over a ternary imide Li2Mg2N3H3.
The reaction details of hydrogen storage process of a ternary imide Li(2)Mg(2)N(3)H(3) are elucidated for the first time. It is found that 1 mole of Li(2)Mg(2)N(3)H(3) converts to a mixture of Mg(NH(2))(2)-2LiH-MgNH on taking up 2 moles of H(2), and that the presence of MgNH in the Mg(NH(2))(2)-2LiH system not only alters the dehydrogenation thermodynamics but also improves the dehydrogenation kinetics.
