摘要：

In order to improve the thermal decomposition performance of AP in solid propellant and reduce its thermal decomposition temperature, the morphology and structure of g-C3N4/Fe2O3 obtained in situ were characterized by SEM, XRD and FT-IR, and the catalytic effect of AP thermal decomposition was investigated by Differential Scanning Calorimeter(DSC). The results show that the composite structure of g-C3N4/Fe2O3 was complete, and the Fe2O3 particles were closely loaded on g-C3N4.When different mass fraction of composite catalyst was added, the low temperature decomposition peak and high temperature decomposition peak of AP were significantly reduced, and the catalytic effect was enhanced with the increase of catalyst addition amount. When the mass fraction of composite catalyst was 5%, the high temperature decomposition peak and the low temperature decomposition peak of AP reduced respectively to 348.1℃ and 281.7℃. These results indicate that g-C3N4/Fe2O3 composite catalyst could effectively reduce the thermal decomposition temperature of AP and improve its thermal decomposition performance. © 2022, Editorial Department of Journal of Propulsion Technology.
