摘　　要：镁系储氢合金具有储氢能力强、原材料来源丰富和安全可靠等优点在近些年的道理的广泛研究,但是依然需要解决吸放氢速率慢、活化能相对较高等难点。鉴于此,文章总结了镁系储氢合金储氢性能近些年的研究进展,介绍了制备工艺、催化剂和其他处理工艺对合金微观结构、热力学性质和储氢性能等的影响,指出对于储氢性能的改善应主要聚焦增加Mg晶界、减弱Mg-H键。The magnesium hydrogen storage alloy has the advantages of strong hydrogen storage capacity,rich source of raw materials,safety and reliability in recent years,but it still needs to solve the difficulties of slow hydrogen absorption and emission rate and relatively high activation energy.Therefore,this paper summarizes the research progress of hydrogen storage properties of magnesium hydrogen storage alloys in recent years,introduces the effects of preparation technology,catalyst and other treatment processes on the microstructure,thermodynamic properties and hydrogen storage properties of the alloys,and points out that the improvement of hydrogen storage properties should mainly focus on increasing Mg grain boundaries and weakening MG-H bounds.
