The catalytic hydrogenation of magnesium under atmospheric pressure has been optimized so that the reaction can be completed within seven hours. The resulted magnesium hydride is in the form of superfine powder with an average primary particle size of 15 nm. This magnesium hydride exhibits higher dehydrogenation/hydrogenation rates than that obtained under pressure with the same catalyst system.
