Claims
- 1. A method of preparing an active magnesium-hydride which can reversibly desorb H.sub.2 in an amount of 6.5-7.65% by weight at about 250.degree.-400.degree. C., consisting essentially of mixing finely divided magnesium hydride with 0.05 to 4% by weight of a finely divided transition metal of Subgroups IV-VIII of the periodic table.
- 2. A method according to claim 1, wherein the mixing is effected in the presence of hydrogen.
- 3. A method according to claim 1, wherein the transition metal is titanium, vanadium, chromium, molybdenum, tungsten, iron, ruthenium, cobalt, rhodium, iridium, nickel, palladium and/or platinum.
- 4. A method according to claim 1, wherein the transition metal comprises nickel, palladium or iron.
- 5. A method according to claim 1, wherein the mixing is effected in a liquid selected from the group consisting of an aliphatic hydrocarbon, an aromatic hydrocarbon, a cycloaliphatic hydrocarbon, an aliphatic ether, an aromatic ether and a cycloaliphatic aromatic ether.
- 6. A method according to claim 1, wherein the mixing is effected by ball milling at a temperature of about -50.degree. C. to +150.degree. C.
- 7. A method according to claim 1, wherein the transition metal is nickel.
