| 摘 要： | 以氧化石墨烯和硝酸铁为原料,采用水热法制备Fe_2O_3/石墨烯复合物。采用XRD、FTIR、RAMAN、SEM等对其结构和形貌进行表征,并通过不同升温速率的TG-DSC研究Fe_2O_3/石墨烯复合物对HMX热分解催化作用。结果表明,在氧化石墨烯被还原为石墨烯过程中,同时Fe_2O_3纳米粒子负载于石墨烯片层上;Fe_2O_3/石墨烯复合物可使HMX热分解活化能降低51.13 kJ·mol~(-1),对HMX有较好的催化作用。

| Abstract: | Fe2 O3/graphene was prepared by a hydrothermal method and using graphene oxide and ferric nitrate as raw materi-als.The structure and morphology of Fe2O3/graphene were characterized by X-ray diffraction,FTIR,Raman,SEM,et al.The catalytic performance of thermal decomposition behavior of Fe2 O3/graphene on the thermal decomposition of HMX was analyzed by differenti-al thermogravimetry(TG) and scanning calorimetry(DSC).The results demonstrate that graphene oxide are reduced to graphene and Fe2 O3/graphene aresimultaneously anchored on graphene sheets;Thermal decomposition activation energy of HMX decrease by 51.13 kJ·mol-1 and obviously catalyze thermal decomposition reaction of HMX. |
