“…The catalytic properties of several materials obtained in this experiment were compared with those that had been reported in the literature, − as shown in Table . These catalysts all showed good catalytic properties, and the activation energy was reduced while the temperature of the high-temperature decomposition peak was lowered, and the catalytic effect of the bimetallic complexes obtained in this experiment was better, and their catalytic properties were further enhanced after they were derivatized.…”

This research delves into the preparation of heteronuclear bimetallic catalysts and explores their catalytic properties in the thermal decomposition of ammonium perchlorate (AP). The study's central focus is on enhancing the thermal decomposition characteristics of AP and, consequently, the combustion performance of composite solid propellants. The synthesized materials underwent structural characterization by XRD, XPS, SEM, and FTIR. Catalytic properties were examined using DTA tests. Notably, catalysts derived from calcination at 500 °C exhibited heightened catalytic activity. They advanced the pyrolysis temperature by 135.4 °C and reduced the activation energy by 82.38 kJ/mol compared with pure AP. To further elucidate the decomposition mechanism of AP, the investigation also employed a combined approach involving DSC-TG-FTIR-MS analysis.
