To overcome the agglomeration of cobalte oxide (Co3O4) nanocatalysts mechanically mixed with ammonium perchlorate (AP) and other additives of rocket propellant, Co3O4/AP have been synthesized successfully with thermal decomposition process using cobalte acetylacetonate (Co(acac)3). The cobalte acetylacetonate was coated on AP by Non-solvent, solvent method at room temperature to make a uniform and steady shell. The scanning electron microscopy image (SEM) of nano-composite revealed that nano-coating of Co(acac)3 had made thin and steady covers on the surface of AP. The catalytic effect of cobalt oxide nano-particles on ammonium perchlorate thermal decomposition was studied by differential scanning calorimetric (DSC) Showed a decrease in the decomposition temperature from 398.04 ◦C to 328 ◦C and the kinetic parameters were determined.
