Abstract
A process in a resulting product of the process in which a hydrogen storage metal amide is modified by a ball milling process using an additive of TPP. The resulting product provides for a hydrogen storage metal amide having a coating that renders the hydrogen storage metal amide resistant to air, ambient moisture, and liquid water while improving useful hydrogen storage and release kinetics.
Claims9
A process of stabilizing a hydrogen storage metal amide from exposure to air and water comprising:
- providing a supply of a hydrogen storage metal amide;
- introducing into the hydrogen storage metal amide an effective amount of TPP;
- ball milling the combination of the hydrogen storage amide and TPP wherein following ball milling, the hydrogen storage metal amide is resistant to water and air decomposition.
A hydrogen storage metal amide resistant to moisture and water comprising:
- a metal amide represented by the general formula MId(NH2)d−1 in which the hydride is preferably represented by the general formula MIIfHf, where MI and MII respectively represent cationic species or a mixture of cationic species other than hydrogen, and d and f respectively represent the average valence states;
- an exterior surface of the metal amide having a coating layer of TPP;
- wherein, the hydrogen storage metal amide having the coating layer is resistant to water and air decomposition.
A metal amide which is resistant to moisture and water consisting essentially of:
- a metal amide particle having an exterior surface of the particle coated with an effective amount of TPP.
