The present invention generally concerns isolated nanoparticles via the decomposition of a ternary metal hydride. More specifically, the present invention harnesses increased energy densities from two distinct nanoparticles isolated by a precise decomposition of LiAlH4. The singular material is air stable and is a nanocomposite of Li3AlH6 nanoparticles, elemental Al nanoparticles, an amount of Ti metal, and a nanoscale organic layer, which we call nMx. The nanocomposite protects and preserves the high energy densities of the core metals isolated from the controlled reaction and makes the nanoparticles safe to handle in air. The final composite is devoid of byproducts or phase transitions that will decrease the energy output of the nanocomposite. The method of the present invention creates a narrow distribution of nanoparticles that have unique burning characteristics useful for many applications.
