Abstract
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.
Claims6
A nanopowder made by a process comprising:
- reacting Ti(BH4)3 with LiAlH4 in an aprotic solvent while being sonicated to produce nanoparticles comprising titanium, boron, and hydrogen;
- wherein the molar ratio of Ti(BH4)3 to LiAlH4 is from 1:1 to 1,000,000:1;
- and
- annealing the nanoparticles under a vacuum;
- wherein the nanopowder comprises at least 90 wt. % elemental amorphous titanium and elemental amorphous boron.
