The project investigates the catalytic effect of titanium nitride and zirconium on the desorption of hydrogen from magnesium hydride. The components for the preparation of hydride nanocomposites were magnesium powder and nano powders TiN and ZrN. During the grinding of the composites, they adsorbed about 6.5 wt.% hydrogen. The size of the crystallites of magnesium hydride obtained by the results of the profile analysis of the diffraction peaks for all composites is in the narrow range - 6… 10 nm. The best catalytic effect was observed for TiN powder: it lowers the activation energy of hydrogen desorption from the composite to 65 kJ / mol. The synthesized nanocomposites of magnesium hydride have also been tested as materials for hydrogen generation devices by hydrolysis. The effective effect of MgCl2 catalyst on the degree of conversion is shown.
