Abstract
Nano-Fe2O3/CNTs catalyzers were synthesized by the sol-gel methods. The technology parameters were optimized by an orthogonal test. The appearance of products was characterized by SEM, TEM and XRD. The catalytic properties of Fe2O3/CNTs on thermal decomposition of RDX were determined by using DSC method. The results show that the surface of CNTs is coated with Fe2O3. When mass fraction of Fe 2O3/CNTs is about 5%, Fe2O3/CNTs catalyzers make the peak temperature of DSC curve for thermal decomposition of RDX decrease by 14. 1°C, and the activation energy of thermal decomposition reaction of RDX obtained by Kissinger method decrease by 38. 5%.
