摘要
The effect of high-pressure (6 gigapascal) and heating (600 degreesC) the hydrogen source of LiAlH4 on the structural and hydrogenation properties of 0.9MgH(2)+0.1Al+0.9Ni+0.1VH(0.9) was investigated. After recovery to ambient conditions, the sample was analyzed using X-ray diffraction, differential scanning calorimetry, thermogravimetry and differential thermal analyses. The results reveal that a nominal hydride phase with the composition of Mg0.90Al0.08Ni0.94V0.08H1.6 can be obtained, in which a maximum H-2-uptake can reach 1.9 wt.%, with hydride decomposition occurring between 160 degreesC and 250 degreesC.
