Abstract: CoC2O4 shows intensive catalytic effect on the thermal decomposition of ammo nium perchlorate (AP). Adding 2% of CoC2O4 to AP decreases the decomposition tem pera ture by 104 ℃ and increases the heat of decomposition from 655 J/g to 1469 J/g. Products of thermal decomposition of AP are H2O , NH3 , O2, HCl , Cl2 , NO , N2O , and NO2. The results show that the new ecological nano-c obalt oxide presents better catalysis performance for thermal decomposition of A P.
