| 摘 要： | 采用置换-扩散法制备得到Mg2NiH4，用SEM、XRD和DSC等对其结构和性能进行了表征。Mg2NiH4纯度较高，含氢量为3.6％，放氢温度为292.4℃。用DSC法研究了Mg2NiH4对高氯酸铵（AP）热分解的催化性能。结果表明：加入含量为10％的Mg2NiH4可使AP高温放热峰温降低108.2℃，使表观分解热增加217.0％，Mg2NiH4对高氯酸铵热分解具有良好的催化作用。Mg2NiH4含量增加，对高氯酸铵热分解的催化作用增强。初步探讨了Mg2NiH4催化高氯酸铵热分解的作用机理。

| Abstract: | Mg2NiH4 was prepared by the replacement-diffusion method，and its structure was characterized with SEM，XRD and DSC.Mg2NiH4 had high purity，a great deal of crackle on the surface，and high activity.Its hydrogen-storage capacity was 3.6% and affranchising hydrogen temperature was 292.4℃.DSC results showed that Mg2NiH4 had good catalytic effect on the thermal decomposition of ammonium perchlorate（AP）.When the content of Mg2NiH4 reached 10%(mass)，the high temperature exothermic peak of AP was decreased by 108.2℃ and the exothermic heat increased by 217.0％.Meanwhile，the catalysis mechanism was discussed. |
