摘　　要：镁基储氢材料具有储氢量高、镁资源丰富以及成本低廉等优点,被认为是极具应用前景的一类固态储氢材料。利用镁基储氢材料供氢主要有热分解放氢和水解产氢2种途径。MgH_(2)的热分解放氢焓值高(75 kJ/mol H),造成其放氢温度较高、动力学差;MgH_(2)的水解过程中,由于常温水解产物Mg(OH)逐渐包裹在MgH_(2)表面,阻隔了MgH_(2)与水的接触,从而导致水解产氢效率较低。近年来,大量研究工作聚焦于改善MgH_(2)的热解/水解供氢性能及实际应用,已经取得了大量成果。针对目前国内外镁基固态储氢材料的研发,总结了材料/结构改性、反应条件对镁基储氢材料的热解/水解性能的影响,重点阐述了固态镁基储氢材料组成成分-微观结构-储放氢性能之间的关系,并对镁基储氢系统及实际应用场景进行了归纳。未来通过镁基固态储运氢技术的发展,将实现氢气的高安全、高效及大规模储运,助力中国氢能产业的发展。Magnesium-based hydrogen storage materials have the advantages of high hydrogen storage capacity,abundant magnesium resources and low cost,and are considered to be of promising application prospects.In recent years,numerous researches have focused on improving the performance of hydrogen supply by pyrolysis/hydrolysis of MgH_(2)and many good achievements have been obtained.Based on the recent research progress,this paper summarizes the effects of the material/structure modification and the reaction conditions on pyrolysis/hydrolysis performance of the magnesium-based hydrogen storage materials,and expounds the relationship between composition-microstructure-properties of solid Mg-based hydrogen storage materials.Meanwhile,the Mg-based hydrogen storage systems and their industrial applications are summarized.At last,the current results of the solid state Mg-based hydrogen storage are summarized and some suggestions for the future investigations are proposed.
