中文摘要:
      氢能的高效安全利用是目前的研究热点之一。针对轻质高容量储氢材料硼氢化合物的安全放氢,探索了一种金属阳离子替代的调控策略,通过对分子结构的调整,实现对[BH4]-基团热力学稳定性的有效调控,达到可控安全放氢的目的。实验以LiBH4为例,采用湿化学法制备Zn(BH4)2和LiZn(BH4)3,并通过工艺优化,阐明了Zn阳离子对硼氢化物的室温热力学稳定性以及热分解行为的影响,为硼氢化合物的进一步安全开发和利用提供了思路。
英文摘要:
      The high safety and efficiency for the spreading usage of borohydrides as solid-state hydrogen storage material are the important research aspect.Aiming at the safe hydrogen release of light and high-capacity hydrogen storage material borohydride,a regulation strategy of metal cation substitution was explored,and the effect of cation substitution on tuning the thermodynamics of [BH4]- unit was investigated.LiBH4 was chosen as an modified example to synthesize Zn(BH4)2 and LiZn(BH4)3 via wet-chemical approach with optimized procedure.The effectiveness of cation substitution was testified to altering the dehydrogenation process with controlling safety,and it certainly offered a way for the safe application of borohydrides.
