摘要
氢能作为一种理想的二次能源受到了国内外科研工作者的广泛关注,研制可以在室温和较低压力下方便、安全、高效地储存氢能的材料是氢能发展的瓶颈.到目前为止,固态储氢材料以能量密度高及安全性好等优势被认为极具应用前景,其中以轻质元素构成的氢化物(包括硼氢化物/铝氢化物(可用通式A(MH4)n表示,其中A是碱金属(Li,Na,K)或碱土金属(Be,Mg,Ca);M是硼或铝;n=1~4)、氨基氢化物(如LiNH2等))、氨硼烷(NH3BH3)、金属有机骨架材料(MOFs)是新型储氢材料研究领域的热点,本文将着重就目前这几类储氢材料的研究当中所涉及到的一些热力学及动力学问题进行总结探讨.
Hydrogen attracts great attention as an ideal secondary energy.Hydrogen production and applications have a variety of solutions,but the storage and transportation still faces a great challenge.Solid-state hydrogen storage materials with advantages of high energy density and safety are considered to have very promising prospects.Hydrides of light elements (including boron hydride,aluminum hydride,etc..It is generally expressed as A(MH4)n,where A is alkali metals (Li,Na,K) or alkaline earth metals (Be,Mg,Ca),and M is B or Al in IIIB family of periodic table,n=1?4),composite hydrides (like LiBH4-MgH2,etc.),ammonia borane and metal organic frameworks (MOFs) are remarkable hydrogen storage materials.We will focus on review of these types of hydrogen storage materials and their thermodynamics and kinetics in the present paper.
