|Abstract:||We report a new chemical reaction between Mg(NH2)2 and LiAlH4 in a molar ratio of 1/1, which releases 8 equiv of H under moderate conditions. X-ray diffraction, Fourier transform infrared spectroscopy, and NMR measurements revealed that an Al-N bond was established right after the occurrence of the reaction. Nitrides are the final dehydrogenation products. Thermodynamic examination reveals that the hydrogen desorption from the post-ball-milled sample is a mild endothermic process, indicating it could be a potential candidate for on-board hydrogen storage. The dehydrogenation mechanism in the mechanochemical and heating treatments was discussed. © 2007 American Chemical Society.|
