Study catalytic effect of CeO2 nanoparticle on thermal decomposition of ammonium perchlorate

This work studied on the thermal decomposition of ammonium perchlorate activated by addition of commercial CeO2 nanoparticles. CeO2 nanoparticles were characterized by X-ray diffraction (XRD) and transition electron microscope (TEM). The TEM study revealed that the majority of CeO2 particles are of 10–30 nm in size. The catalytic activities of CeO2 nanoparticles on the thermal decomposition of ammonium perchlorate were investigated by thermogravimetric analysis (TGA) coupled with differential scanning calorimeter (DSC). The results imply that the catalytic performance of CeO2 nanoparticles is significant and the decrease in the thermal decomposition temperature and the increase in the heat decomposition AP. So that, adding 2 Wt.% of CeO2 nanoparticles to AP decreases the thermal decomposition temperature from 423.89 to 330.89 °C. Also, Adding 2 Wt.% of CeO2 nanoparticles to AP increases the heat decomposition from 835 to 1517.22 J/g.
