Abstract

Since Nanoparticles (NPs) tend to agglomerate, their catalytic activities decrease during propellant operation. Therefore, loading the nanoparticles onto the support is a general method to prevent the agglomeration and maintain the catalytic activities of the nanoparticles. Three dimensional (3D) graphene has high surface area and porous structure. Furthermore, 3D-graphene is an efficient support to grow and anchor NPs with high loading and better dispersity. In this study, firstly CuCr2O4 spinel NPs and CuCr2O4@3D-GFs nanocomposite were synthesized. Then, the structure and particles size were determined by XRD, FESEM and TGA. The as-prepared CuCr2O4 NPs and CuCr2O4@3D-GFs nanocomposite were used as a promising catalyst for the Thermal Decomposition of Ammonium Perchlorate (AP) and their catalytic performance was investigated by differential scanning calorimetry and thermal gravimetric analysis (DSC/TGA). Thermal Decomposition of AP in the presence 4 wt % CuCr2O4 NPs and 2 and 4 wt % CuCr2O4@3D-GFs nanocomposite prepared by solventantisolvent method showed that two exothermic peaks of AP merges into one peak and high-temperature decomposition appeared at 348, 332 and 321° C, respectively.
