Abstract: Optimizing the thermal behavior of ammonium perchlorate (AP) is the key to promoting the development of composite solid propellants. In this work, MgCo2O4 nanocomposites modified with highly dispersed two-dimensional carbon materials (rGO, g-C3N4) were prepared by one-pot synthesis. The structure of the composite was characterized by XRD, SEM, TEM, and XPS. The catalytic performance of MgCo2O4 (rGO, g-C3N4) was examined by DSC. The results show that MgCo2O4/rGO can effectively reduce the high-temperature decomposition (HTD) peak temperature of AP to 272.3 °C (198.9 °C lower), and the apparent activation energy of AP is reduced from 296.2 kJ·mol−1 to 110.3 kJ·mol−1. The introduction of rGO effectively inhibits the agglomeration of MgCo2O4 nanoparticles while facilitating electron transfer from MgCo2O4 to AP, thereby accelerating its thermal decomposition process. This work provides a feasible strategy for optimizing the thermal behavior of AP.
