Abstract:
1. A hydrogen storage material capable of a hydrogenated state and dehydrogenated state, the hydrogen storage material comprising a plurality of hydrogen storage molecular units, each hydrogen storage molecular unit comprising: a transition metal; and an element from period 2 of the periodic table bonded to the transition metal, wherein each of the hydrogen storage molecular units includes two titanium atoms bonded to two nitrogen atoms and a boron atom bonds a nitrogen atom of a first hydrogen storage molecular unit to a nitrogen atom of a second hydrogen storage molecular unit, wherein each of the two nitrogen atoms is bonded to each of the two titanium atoms, and wherein the hydrogen storage material includes at least 6.5% molecular hydrogen by weight when in the hydrogenated state and is stable at temperatures below about 200° C. and at pressures of about 1 atm and below.
