Investigation of the catalytic activity effect of Co(acac)3 nanoparticle on thermal decomposition of ammonium perchlorate and its Kinetic parameters

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.
