The present invention relates to a doped hydrogen storage material according to the general formula: Mg. By Mz Hn wherein : (i) the ratio of x/y is in the range of from 0.15 to 1.5; (ii) z is in the range of from 0.005 to 0.35; (iii) x+y+z equals 1; (iv) M= is one or more metals selected from the group of selected Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu and Zn; (v) n is no more than 4y; and wherein x/y does not equal 0.5 and at least part of the doped hydrogen storage material is amorphous. The present invention further relates to the use of doped hydrogen storage materials according to the invention for storing hydrogen and a method for reversibly desorbing and/or absorbing hydrogen.

La présente invention concerne un matériau de stockage dhydrogène dopé selon la formule générale : Mgx By Mz Hn où : (i) le rapport de x/y se situe dans la plage allant de 0,15 à 1,5; (ii) z se situe dans la plage allant de 0,005 à 0,35; (iii) x + y + z est égal à 1; (iv) M représente un ou plusieurs métaux choisis dans le groupe de Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu et Zn; (v) n nest pas supérieur à 4y; et où x/y nest pas égal à 0,5 et au moins une partie du matériau de stockage dhydrogène dopé est amorphe. La présente invention concerne en outre lutilisation de matériaux de stockage dhydrogène dopé selon linvention pour stocker de lhydrogène et un procédé pour désorber et/ou absorber de façon réversible lhydrogène.
