摘要

Abstract

The monodispersed Co nanoparticles were successfully prepared by means of hydrogen plasma method in inert atmosphere.The particle size

specific surface area

crystal structure and morphology of the samples were characterized by transmission electron microscopy(TEM)

BET equation

X-ray diffraction(XRD)

and the corre-sponding selected area electron diffraction(SAED).The catalytic effect of Co nanoparticles on the decomposition of ammonium perchlorate(AP)was investigated by differential thermal analyzer(DTA).Compared with the ther-mal decomposition of pure AP

the addition of Co nanoparticles(2%-10%

by mass)decreases the decomposition temperature of AP by 145.01-155.72℃.Compared with Co

nanoparticles and microsized Co particles

the catalytic effect of Co nanoparticles for AP is stronger.Such effect is attributed to the large specific surface area and its interaction of Co with decomposition intermediate gases.The present work provides useful information for the application of Co nanoparticles in the AP-based propellant.
