| 摘 要： | 镁基储氢材料由于价格低廉、储氢量高和安全性好等优点，受到人们的广泛关注。然而较高的吸放氢温度和较慢的动力学性能在一定程度上限制了其在储氢方面的进一步研究和应用。目前，该体系的研究热点主要集中在优化不同的改性方法，目的是得到低成本、大批量、小颗粒和稳定性高的纳米MgH2，并已取得了一定的进展；但要获得能够在环境温度下具有理想热力学性能和实际应用价值的镁基储氢材料，仍面临巨大挑战。本文中，我们总结了镁基合金储氢材料的研究进展，并进一步梳理了文献中关于优化和改变热力学和动力学性能的方法，为获得具有高容量、低成本、吸放氢动力学和热力学性能优异的镁基储氢材料提供更好的实验经验和理论支持。

| Abstract: | Mg-based hydrogen storage materials have attracted much attention because of their low price, high hydrogen storage capacity and fine safety. However, its higher temperature of hydrogen absorption and desorption and slow kinetic properties limit its further research and application in hydrogen storage. Recent research mainly focus on exploring different modification methods to obtain low cost, large quantities, small particles and high stability of MgH2 nanopowders, and some progress has been made; However, it is still a great challenge to obtain magnesium-based alloy hydrogen storage materials which have ideal thermodynamic properties and practical application value at ambient temperature. In this review, we summarized recent progress in the research on magnesium-based alloy hydrogen storage materials, and further categorized reported methods on changing thermodynamic and kinetic properties of magnesium-based alloy, to provide better empirical and theoretical support for obtaining magnesium-based hydrogen storage materials with high capacity and excellent kinetic & thermodynamic properties in hydrogen adsorption & desorption. |
