摘　　要：镁基储氢材料因其储氢量大、成本低廉等而被认为是最有前途的固态储氢材料之一.然而其过慢的吸放氢速率和过高的吸放氢温度限制了它的应用.元素取代和纳米复合是改善镁基储氢材料性能的重要方法.本文对镁基储氢材料的改性方法进行了综述,并对其发展趋势进行了展望.Mg-based hydrogen storage materials are considered to be one of the most promising soild hydro- gen storage materials because of its advantage such as large hydrogen storage capacity, low cost and so on. However, the slow absorption/desorption kinetics and the high absorption/desorption temperature hin- dered the application of the Mg-based hydrogen storage alloys. Element partial substitution and nanocom- posite are the preferred methods to improve the performance of magnesium-based hydrogen storage materi- als. In this paper modification of Mg-based hydrogen storage materials are reviewed and the development trend of the materials is also suggested.
