A composition capable of absorbing and desorbing hydrogen comprising Li3N and a halogen, such as Cl2, or a halogen-containing compound where the halogen is covalently bound or anionic. The process for doping Li3N is performed by milling a mixture Of Li3N and the halogen or halogen-containing compound. Examples of halogen-containing compounds include LiCl, NaCl, KCl, MgCl2, AlCl3, AlF3, TiCl4, LiBr, LiF, NH4Cl, CCl4, CaCl2, etc. The hydrogen storage ability of these compounds is reversible. The compounds can be used repeatedly in applications where hydrogen supply is needed. |
