The effect of rGO-Fe2O3 nanocomposites with spherical, hollow and fusiform microstructures on the thermal decomposition of TKX-50

rGO-Fe 2 O 3 nanocomposites with spherical, hollow and fusiform Fe 2 O 3 (s, h and f) microstructures have been successfully fabricated using DMF as solvent via a facile solvothermal method. The morphologies and compositions of the as-synthesized rGO-Fe 2 O 3 (s, h and f) nanocomposites were systematically studied using SEM, TEM , XRD , FTIR, RAMAN and XPS analysis . The rGO-Fe 2 O 3 (s, h and f) nanocomposites were used to catalyze the thermal decomposition of energetic TKX-50 and the corresponding kinetic parameters were calculated using an isoconversional model. The catalytic performance of Fe 2 O 3 (s, h and f) during the thermal decomposition of TKX-50 was significantly improved after being anchored onto the surface of graphene oxide . The as-synthesized rGO-Fe 2 O 3 (h) and rGO-Fe 2 O 3 (s) nanocomposites have an excellent effect toward reducing the temperature and apparent activation energy ( E a ) for TKX-50 decomposition, respectively. The excellent catalytic performance of rGO-Fe 2 O 3 (h) nanocomposite can be attributed to its external and internal surfaces, which provide more active sites for TKX-50 decomposition. In addition, the interactions formed between rGO and Fe 2 O 3 have a positive effect toward reducing the E a .
