Title: Nanostructured metal amides and nitrides for hydrogen storage

Abstract

Nanostructured metal amides and nitrides are incorporated into nanoporous templates, such as carbon, using liquid ammonia as a solvent/reagent. This leads to unexpected improvements in metal amide nanoconfined hydrogen storage materials. The resulting nanostructured materials may reversibly absorb and desorb large capacities of hydrogen under conditions that are much milder compared to what has been achieved with bulk materials. In addition, the nanoconfined materials may reduce the amounts of ammonia released upon dehydriding, which may make the released hydrogen gas purer and may limit the capacity loss. In addition, nanoconfinement may simplify the reaction mechanism, eliminating undesired metal imide intermediates and promote hydrogen cycling under mild conditions. The liquid ammonia method also allows the simultaneous introduction of catalytic additives along with the parent hydrogen storage material.
