Abstract
A doped hydrogen storage material according to the general formula: MgxByMzHn 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 doped hydrogen storage materials are used for storing hydrogen, and also disclosed is a method for reversibly desorbing and/or absorbing hydrogen.
