Abstract
A mechanically alloyed hydrogen storage material having 75-95 atomic percent Mg, 5-15 atomic percent Ni, 0.5-6 atomic percent Mo, and at least one additional element selected from the group consisting of Al, C, Ca, Ce, Co, Cr, Cu, Dy, Fe, La, Mn, Nd, Si, Ti, V, and Zr, preferably between 1-15 atomic %. The mechanically alloyed hydrogen storage preferably contains from 3-15 atomic % C and at least one other element selected from the group consisting of Al, Ca, Ce, Cu, Dy, Fe, La, Mn, and Nd. The hydrogen storage materials are created by mechanical alloying in a milling apparatus under an inert atmosphere, such as argon, or a mixed atmosphere, such as argon and hydrogen. The speed and length of the milling are varied.
