Abstract
A composition and its method of production are provided. The composition includes at least one zero-valent metallic element atom in complex with at least one hydride molecule. The method of production includes ball-milling an elemental metal in a high-surface area form, with a hydride. The composition can be useful as a reagent for the synthesis of zero-valent metallic elemental nanoparticles.
