Effects of ball milling and additives on dehydriding behaviors of well-crystallized Mg(BH 4) 2

Well-crystallized Mg(BH 4) 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(BH 4) 2 initiates at approximately 535 K and about 13.7 mass% of hydrogen is desorbed. Comp...

Summary:Well-crystallized Mg(BH 4) 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(BH 4) 2 initiates at approximately 535 K and about 13.7 mass% of hydrogen is desorbed. Compared with the as-synthesized Mg(BH 4) 2, few changes are observed in the samples after ball milling, while the initial dehydriding temperature of Mg(BH 4) 2 is significantly reduced by the addition of TiCl 3, i.e. from 535 K down to 361 K.
