Abstract: The interaction between Mg(NH2)2 and NaH enable Mg-Na-N-H potential candidate for hydrogen storage. Upon heating to 120°C the mixture of Mg(NH2)2 and NaH gives out hydrogen and converts to a new Mg-Na-N-H structure, which can re-absorb hydrogen at temperature as low as 60°C. Increasing NaH content enhances the chemical stability of the Mg-Na-N-H system; however, it also leads to the high-temperature shift of hydrogen absorption. The desorption plateau is relatively flat, however, pressures are generally low at temperature below 200°C. © 2004 Elsevier B.V. All rights reserved.
