<p>A process for the reversible storage of hydrogen, comprising bringing into contact a material that consists of magnesium elements and nitrogen elements with gaseous hydrogen leading to the formation of an amide or corresponding hydrides, comprises the use of a balanced system corresponding to the formula: Mg3N2<img id="CUSTOM-CHARACTER-00001" he="2.46mm" wi="2.46mm" file="US07608239-20091027-P00001.TIF" alt="custom character" img-content="character" img-format="tif"/>Mg(NH2)2+2MgHn where n is the number of hydrogen atoms corresponding to the stoichiometry of the hydride or hydrides formed. The material can also comprise, in a minor proportion, at least one transition metal of groups 3 to 12 of the periodic table that is selected from among Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn and Pd.</p> |
