硼氢化锂(LiBH4)因其高达18.4wt%的含氢量而被用于贮氢材料的研究.但LiBH4放氢和再氢化温度较高,因此如何使其去稳定化(destabilization)从而降低其放氢温度成为研究的热点之一.本文报告了金属硼化物MB2 (M=Mg,Ti,Zr)和MB6 (M=Ca,La)对LiBH4的去稳定化作用.MB2的添加使LiBH4的放氢温度从450℃降低至350℃,而MB6对LiBH4放氢温度的降低作用更大;而且这些金属硼化物还能有效促进LiBH4放氢后的再氢化反应.XRD,FT-IR,DSC和MS等分析结果表明,金属硼化物在LiBH4的首次放氢过程中起着催化剂的作用,并参与随后的再氢化反应.
