摘　　要：本文通过一种新的合成路线合成了二茂铁功能化的氧化石墨烯(GO-EDA-Fc)。利用傅里叶变换红外光谱和扫描电子显微镜对其结构和形貌进行了表征。通过热重分析(TGA)研究了其对高氯酸铵(AP)热分解的催化性能,结果表明,氧化石墨烯和二茂铁表现出很好的协同催化效果,对AP热分解具有高的催化活性。催化效果随着GO-EDA-Fc加入量的增加而增强,当加入4wt%的GO-EDA-Fc时,AP的高温分解峰的峰值温度下降了60℃,低温分解峰的峰值也有降低。文中还对催化机制进行了研究。A new ferrocene modified graphene oxide nano-material （GO-EDA-Fc） was synthesized via a new synthesis route. The GO-EDA-Fc was characterized by Fourier transform infrared spectra, and its morphology was observed under scanning electron microscopy. The graphene oxide was covalently decorated by ferrocene. The catalytic performance of GO-EDA-Fc in the thermal decomposition of ammonium perchlorate （AP） was investigated by thermogravimetric analysis （TGA）. The results showed that GO-EDA-Fc exhibited high catalytic activity. When 4wt% of GO-EDA-Fc was added, the peak temperature of the high-temperature decomposition peak of AP had a decrease of 60℃ and the peak of the low-temperature decomposition was shifted to lower as well. The more GO-EDA-Fc was added, the better catalytic performance would be achieved. Notably, the ferrocene functionalized graphene oxide had shown a synergistic catalytic effect. The mechanism of promote action was also investigated.
