Abstract

Well-crystallized Mg(BH₄)₂ was chemically synthesized and the effect of ball milling and Ti-based additives on the dehydriding properties were investigated. The dehydriding reaction of the as-synthesized Mg(BH₄)₂ initiates at approximately 535 K and about 13.7 mass% of hydrogen is desorbed. Compared with the as-synthesized Mg(BH₄)₂, few changes are observed in the samples after ball milling, while the initial dehydriding temperature of Mg(BH₄)₂ is significantly reduced by the addition of TiCl₃, i.e. from 535 K down to 361 K.
