摘要：

Magnesium borohydride (Mg(BH4)(2)) is a promising material for hydrogen storage because of its high gravimetric storage density (15.0 mass%). We intended to synthesize Mg(BH4)(2) by decomposition reaction of LiBH4 with MgCl2 by heat treatment without using a solvent, where the product consists of LiCl and a compound of magnesium, boron and hydrogen. Hydrogen desorption temperature of the product is approximately 100 K lower than that of LiBH4 and the decomposition consists of a two-step reaction. The products of the 1st and 2nd decomposition reactions are MgH2 and Mg, respectively. This result indicates the following two-step reaction (1st reaction: Mg(BH4)(2) --> MgH2 + 2B + 3H(2), 2nd reaction: MgH2 --> Mg + H-2). The first decomposition peak is dominant and is around 563 K. The 2nd decomposition occurs at the temperature greater than 590 K. (C) 2007 Elsevier Ltd. All rights reserved.
