Synthesis of Fe3O4/Graphene Nanocomposite and Investigation of Their Catalytic Activity on Thermal Decomposition of Ammonium Perchlorate Particles

In this study, Fe3O4/ graphene nanocomposite was prepared by a gas/liquid interface reaction and characterized by XRD, IR and SEM techniques. Transmission electron microscope images revealed that the ultrafine Fe3O4 NPs are homogeneously deposited on the supporting G-O sheets and graphene oxide sheets could hinder the aggregation of Fe3O4 NPs. Then, the catalytic performance of the synthesized material on the thermal decomposition of ammonium perchlorate (AP) was investigated by ThermoGravimetry Analysis (TGA) and differential scanning calorimetry (DSC) techniques. The results of the thermal analysis showed that the composites exhibit better catalytic effect for the thermal decomposition of ammonium perchlorate than Fe3O4 NPs due to the combination of graphene sheets and Fe3O4 NPs.
