Controlled Release of Hydrogen Isotopes from Hydride-Magnetic Nanomaterials.

In this work, hydrogen isotopes in the form of protium and deuterium were rapidly desorbed from magnetic-hydride iron oxide-palladium (FeO-Pd) hybrid nanomaterials using an alternating magnetic field (AFM). Palladium (Pd), a hydride material with a well-known hydrogen isotope effect, was deposited on an FeO magnetic nanoparticle support by solution chemistries and used as a hydrogen isotope storage component. The morphological, structural, optical, and magnetic studies reveal that the FeO-Pd nanoparticles are hybrid structures exhibiting both hydrogen isotope storage (Pd) and magnetic (FeO) properties.
