ABSTRACTLiCoO2 (LCO) powders were protonated and their catalytic activity on the thermal decomposition of ammonium perchlorate (AP) was tested using differential scanning calorimetry thermogravimetric analysis. Powders characterized SEM, XRD, BET surface area analysis to quantify morphology structure. The showed that enhanced in AP over commercial unmodified LiCoO2, Fe2O3 Co3O4 catalyst powders. activation energies investigated model-free Kissinger method, possible mechanisms governing are discussed. decreased significantly by use these catalysts. For neat AP, LCO, LCO energy for LTD HTD were: 104 ± 5 kJ/mol 143 4 kJ/mol, 89 92 14 76 6 98 7 respectively. We believe hydrogen vacancies lattice act as reaction sites AP.KEYWORDS: Ammonium perchloratecatalysisDSCmetal oxideprotonation AcknowledgmentsThis research sponsored Air Force Office Scientific Research Award No: FA9550-19-1-0008.
