Research Abstract

Mechanistic clarification and performance improvement of de/rehydrogenation of metal borohydrides with a focus on intermediates have been systematically investigated. The formation of polyatomic anion [B12H12]2-from [BH4]-was found to occur via the gradual evolution of the B-H anion, such as [BH4]-→ [B2H6]2-→[B5H9]2-→ [B12H12]2-. Dehydrogenation of reactive composite hydrides 2LiBH4 + MgH2largely depends on the hydrogen pressure and the formation of intermediate Li2B12H12 was found to form only at pressures lower than 1.0 MPa. The different boron-related species between the dehydrogenated Mg(BH4)2 and Ca(BH4)2 would afford different rehydrogenation performance, i.e. Ca(BH4)2 showed better rehydrogenation than Mg(BH4)2.In conclusion, controlling of the formation of intermediates during the dehydrogenation of metal borohydrides would be of great importance for substantial improvement of hydrogen storage properties.
