Hydrogen generation from a sodium borohydride-nickel core@shell structure under hydrolytic conditions.

ABSTRACT: Sodium borohydride (NaBH₄) is an attractive hydrogen carrier owing to its reactivity with water: it can generate 4 equivalents of H₂ by hydrolysis (NaBH₄ + 4H₂O → NaB(OH)₄ + 4H₂). Since using NaBH₄ in the solid state is the most favorable way to achieve a high gravimetric hydrogen storage capacity (theoretical maximum of 7.3 wt%), we have investigated the possibility of developing a core@shell nanocomposite (NaBH₄@Ni) where a metallic nickel catalyst facilitating the hydrolysis is directly supported onto NaBH₄ nanoparticles. Following our initial work on core-shell hydrides, the successful preparation of NaBH₄@Ni has been confirmed by TEM, EDS, IR, XRD and XPS. During hydrolysis, t
