View the Complete Application at the US Patent & Trademark Office
A solid state hydrogen storage system and materials are provided. Hydrogen storage is provided by the formation of metal hydrides in a nanoporous metal framework. H.sub.2 can be effectively released from the hydride that is made directly during the synthesis processes at just 100.degree. C. Dealloying using galvanic corrosion in a metal ion electrolyte and in a hydrogen containing atmosphere is used to create monolithic nanoporous metal frameworks and the simultaneous formation of metal hydrides within the porosity. The nanoporous frameworks have a tunable plasmon resonance and morphology. The system can reversibly store hydrogen in the nanoporous framework using hot electrons generated either by surface plasmons or by exothermic galvanic replacement reactions to form metal hydrides.
