摘　　要：镁基储氢合金由于储氢量高,价格低廉,无毒性,且安全性高等优势被认为是最有发展前途的金属基储氢材料。然而,由于Mg-H键很稳定,镁基氢化物不仅放氢动力学迟缓而且放氢温度较高。这些问题的存在使镁基储氢材料的应用仍难以实现。鉴于此,从镁基储氢合金的改性与应用角度,较全面地综述了其近十几年来的研究发展现状。Taking the characteristics such as large hydrogen storage capacity,cheap price,low toxicity and high safety into consideration,the Mg-based hydrogen storage alloys are regarded as one of the most promising candidates among the metal hydrogen storage materials.Nevertheless,the high stability of Mg-H bond results in the poor hydrogen desorption kinetics and excessive temperature of hydrogen evolution,making practical application of Mg-based materials difficult to achieve.In view of this,the modification and application of Mg-based hydrogen storage alloys are reviewed comprehensively in this paper.
