The unique nature of plasmon-driven chemistry motivates the design and development of novel materials and composites for new applications. This methodology can result in important advances in energy storage by enabling the rapid release of hydrogen at low temperatures and pressures. Dehydrogenation reactions from traditional metal hydride materials require high temperatures. This work explores a dehydrogenation process using plasmonic nanomaterials combined with metal hydrides. Through localized heating via surface plasmon excitation, the bulk thermal signature for hydrogen release can be significantly reduced. In another example, thin coatings grown by atomic layer deposition onto metal hydrides can produce changes in the photo-initiated reaction selectivity based on tailoring the mass transfer of the reactants to the catalyst surface.
