A nanoparticle of a decomposition product of a transition metal aluminum hydride compound, a transition metal borohydride compound, or a transition metal gallium hydride compound. A process of: reacting a transition metal salt with an aluminum hydride compound, a borohydride compound, or a gallium hydride compound to produce one or more of the nanoparticles. The reaction occurs in solution while being sonicated at a temperature at which the metal hydride compound decomposes. A process of: reacting a nanoparticle with a compound containing at least two hydroxyl groups to form a coating having multi-dentate metal-alkoxides.

Metal hydride nanoparticles

A transition metal amino borohydride material includes a first row transition metal in conjunction with an amine ligand and borohydride, in a condition of having been thermally treated to a temperature of at least 70&#xb0; C. and up to but not including 800&#xb0; C. An exemplary such material, Fe(DETA)(BH)having been heat treated at 300&#xb0; C., had good hydrogen storage characteristics.
