摘　　要：Mg(NH2)2-2Li H材料是近年来发展起来的几种最具应用潜力的高容量储氢材料之一.由于具有较合适的吸放氢热力学性能、相对较低的吸放氢操作温度、较高的可逆储氢容量和较优的吸放氢循环稳定性,Mg(NH2)2-2Li H材料现已成为储氢材料研究领域的一个热点.本文综述了Mg(NH2)2-2Li H材料近年来的研究进展,重点关注了材料的组分、晶体结构、颗(晶)粒尺寸和催化动力学改性等对材料储氢性能的影响及储氢机理,总结了Mg(NH2)2-2Li H储氢材料存在的技术问题并指出了今后的研究方向.Mg（NH2）2-2LiH composite is one of the most promising high-capacity hydrogen storage materials developed in recent years. Research on Mg（NH2）2-2LiH material for hydrogen storage is of considerable interest because of its favorable thermodynamic properties, high reversible hydrogen capacity, relatively low operating temperatures, and good cycling stability for dehydrogenation/hydrogenation. In this review, the recent progress in the hydrogen storage properties of Mg（NH2）2-2LiH material was systematically summarized. The focus is on the effect of material composites, crystal structures, particle （grain） sizes, and catalysts on the hydrogen storage properties of the Mg（NH2）2-2LiH material, and their reaction mechanisms for hydrogen storage. The challenges in and direction for further improving the hydrogen storage properties of the Mg（NH2）2-2LiH material are also pointed out.
