In silil catalytic thermal decomposition of ammonium perchlorate (AP) over CoC2O4 was investigated. The catalytic activity measurements were carried out by DSC and TG-MS. The results show that the new ecological nano-cobalt oxide exhibits better catalytic performance in thermal decomposition of AP. Adding 2%, Of CoC2O4 to AP decreases the decomposition temperature by 104 degrees C and increases the beat of decomposition from 655 J/g to 1 469 J/g. Products of thermal decomposition of AP are H2O, NH3, O-2, HCl, Cl-2, NO, N2O, and NO2. The oxidation of adsorbed ammonia by cobalt oxides via the superoxide active centers takes place oil the surface of cobalt oxide. The presence of oxygen call accelerate the oxidation thermal decomposition process of AP, with a clear increase in DSC beat release.
