In this paper, the ultrafine Fe-O compound/ammonium perchlorate (AP) nanocomposites were prepared via in-suit growth method. The structure and morphology of the nanocomposites were characterized by infrared spectra, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion X-ray spectrometer (EDS) and transmission electron microscopy (TEM) test. The results showed that the prepared Fe-O compound nanoparticles were amorphous state and deduced as 2L-ferrihydrite. The size of Fe-O compound/AP nanocomposites could be effectively controlled by changing the recrystallization condition. 2L-ferrihydrite nanoparticles was evenly dispersed in the nanocomposites proved by EDS and TEM analysis. Furthermore, the thermal decomposition of Fe-O compound/AP nanocomposites was analysized by TG-DSC method. The prepared 2L-ferrihydrite nanoparticles of the nanocomposites showed good catalytic effect on AP because of their decreasing the decomposition temperature and increasing the total heat release of AP.

本文采用室内生长法制备了超细的Fe-O化合物/高氯酸铵（AP）纳米复合材料。通过红外光谱，X射线衍射（XRD），扫描电子显微镜（SEM），能量色散X射线光谱仪（EDS）和透射电子显微镜（TEM）测试表征了纳米复合材料的结构和形态。结果表明，所制备的Fe-O化合物纳米颗粒为非晶态，并被推导为2L亚铁水合物。通过改变重结晶条件，可以有效地控制Fe-O化合物/ AP纳米复合材料的尺寸。通过EDS和TEM分析证明，2L-水铁矿纳米颗粒均匀分散在纳米复合材料中。此外，通过TG-DSC方法分析了Fe-O化合物/ AP纳米复合材料的热分解。
