A facile one-pot solvothermal synthesis of CoFe2O4/RGO and its excellent catalytic activity on thermal decomposition of ammonium perchlorate

摘要: CoFe2O4/RGO hybrids have been successfully fabricated via a facile one-pot solvothermal method, which were characterized by X-ray diffraction (XRD), Raman, Fourier-transform infrared spectroscopy (FT-IR) and photoelectron (XPS). During this process, graphene oxide was reduced to (RGO) CoFe2O4 nanoparticles deposited on the RGO. Scanning electron microscopy (SEM) transmission (TEM) revealed that average size of 120 nm, smaller than bare CoFe2O4, implying RGO could effectively prevent from aggregating. To investigate catalytic activity as-synthesized particles hybrids, thermal decomposition ammonium perchlorate (AP) differential analyser (DTA). Both two exothermic processes merged into sole process with addition though there no change in position phase transition temperature AP. Moreover, is higher due large surface area enhanced properties hybrids. The programmed reduction (TPR) measurements showed decreased 55 °C compared further confirmed nanocomposites. Hence, be promising additive modifying burning behaviour AP-based composite propellant.
