采用扩散-扩散法（RDM）成功合成了Mg_2Ni_（0.75）Fe_（0.25）-Mg（摩尔比为2：1）贮氢体系。进行了氢解吸过程的研究。结果表明，压力-组成等温线（P-C-T）特征、平台压力和储存容量随温度变化。本系统对应于具有最佳存储容量（3.3wt.%）的新型储氢材料。
The hydrogen-storage system Mg2Ni0.75Fe0.25-Mg (molar ratio is 2:1) has been successfully synthesized by the replacement-diffusion method (RDM). A study of the hydrogen desorption process was carried out. The results indicated that the pressure-composition isotherm (P-C-T) characteristics, plateau pressure and storage capacity change with temperature. The present system corresponds to a new hydrogen storage material with an optimum storage-capacity (3.3 wt.%).
