Abstract: (2766 Views)

Nanoparticles (NPs) tend to agglomerate consequently 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 structur. 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. Thenthe the structure and size of the particles were determined by XRD,FESEM and TG. 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 % CuCr₂O₄NPs and 2 and 4 wt % CuCr₂O₄@3D-GFs nanocomposite prepared by solvent-antisolvent method showed that two exothermic peaks of AP merges into one peak and high-temperature decomposition appeared at 348, 332 and 321°C, respectively.

Keywords: Ammonium Perchlorate, Thermal Decomposition, Nano Catalyst, Copper Chromite, Three-dimensional Graphene.
