rGO-Fe₂O₃ nanocomposites with spherical, hollow and fusiform Fe₂O₃ (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-Fe₂O₃ (s, h and f) nanocomposites were systematically studied using SEM, TEM, XRD, FTIR, RAMAN and XPS analysis. The rGO-Fe₂O₃ (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 Fe₂O₃ (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-Fe₂O₃ (h) and rGO-Fe₂O₃ (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-Fe₂O₃ (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 Fe₂O₃ have a positive effect toward reducing the E_a.

以DMF为溶剂，通过简便的溶剂热法成功制备了具有球形，空心和梭形Fe ₂ O ₃（s，h和f）微结构的rGO-Fe ₂ O ₃纳米复合材料。使用SEM，TEM，XRD，FTIR，RAMAN和XPS分析系统地研究了合成的rGO-Fe ₂ O ₃（s，h和f）纳米复合物的形貌和组成。使用rGO-Fe ₂ O ₃（s，h和f）纳米复合材料催化高能TKX-50的热分解，并使用等转换模型计算了相应的动力学参数。Fe ₂ O ₃的催化性能锚定在氧化石墨烯表面后，TKX-50的热分解过程中的（s，h和f）得到显着改善。刚合成的rGO-Fe ₂ O ₃（h）和rGO-Fe ₂ O ₃（s）纳米复合材料分别在降低温度和TKX-50分解的表观活化能（E _a）方面具有优异的效果。rGO-Fe ₂ O ₃（h）纳米复合材料的出色催化性能可归因于其外表面和内表面，它们为TKX-50分解提供了更多的活性位点。此外，rGO与Fe ₂ O ₃之间形成了相互作用对降低E _a有积极作用。
