Abstract
A process and a resulting product by process of an aluminum hydride which is modified with by physically combining in a ball milling process an aluminum hydride with a triammonium salt of aurin tricarboxylic acid. The resulting product is an aluminum hydride which is resistant to air, ambient moisture, and liquid water while maintaining useful hydrogen storage and release kinetics.
Claims6
A process of stabilizing a hydride with respect to exposure to air and water comprising:
- providing a supply of a hydride;
- introducing into said hydride an effective amount, of a triammonium salt of aurin tricarboxylic acid;
- ball milling the hydride and triammonium salt of aurin tricarboxylic acid wherein following ball milling, the aluminum hydride is resistant to water and exposure to air.
A moisture and water resistant aluminum hydride comprising:
- an aluminum hydride particle having an exterior surface of the particle coated with a triammonium salt of aurin tricarboxylic acid wherein the coated aluminum hydride is stable when exposed to water.
A moisture and water resistant aluminum hydride consisting essentially of:
- an aluminum hydride particle having an exterior surface of the particle coated with a triammonium salt of aurin tricarboxylic acid wherein the coated aluminum hydride is stable when exposed to water.
