采用简单的原子层沉积(ALD)方法制备了纳米Fe2O3修饰的还原氧化石墨烯(rGO@Fe2O3)。采用扫描电子显微镜、透射电子显微镜、X射线衍射仪和X射线光电子能谱等技术对样品的成分和形貌进行了表征。在石墨烯纳米片上成功地实现了致密堆积的Fe2O_3纳米粒子的均匀分散，与未负载的Fe2O_3纳米粒子相比，改善了空间分布，增加了活性中心的数量。差示扫描量热分析(DSC)结果表明，rGO@Fe2O3复合材料在高氯酸铵(AP)的热分解反应中表现出良好的催化活性，这可能是由于rGO纳米片和负载型Fe2O3纳米粒子的协同作用所致。ALD已被证明是设计和开发新型材料作为高效燃烧催化剂的有效途径。
Reduced graphene oxide (rGO) decorated with finely dispersed Fe2O3nanoparticles (rGO@Fe2O3) was prepared through a facile atomic layer deposition (ALD) route. Compositional and morphological characterizations were conducted using various techniques including scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS). A uniform dispersion of densely packed Fe2O3nanoparticles has been successfully achieved on the graphene nanosheets, leading to improved spatial distribution as well as increased number of active sites compared to unsupported Fe2O3nanoparticles. Differential scanning calorimetry (DSC) results show that rGO@Fe2O3composites exhibit excellent catalytic activities in the thermal decomposition of ammonium perchlorate (AP), which are probably due to the synergistic effect of the rGO nanosheets and the supported Fe2O3nanoparticles. ALD has been proved to be an effective approach to design and develop new classes of materials as efficient combustion catalysts.
