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.
