Study of Three-Dimensional Porous Graphene Oxide Aerogel for Catalyzing the Thermal Decomposition of Ammonium Perchlorate

Abstract

In this work, a three-dimensional porous graphene oxide aerogel (GA) was prepared using a hydrothermal method and vacuum freeze-drying process. The prepared GA and raw material graphene oxide (GO) were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). The results show that GA is fluffy and porous and can be adsorbed on the surface of ammonium perchlorate(AP) after being mixed with AP. The formation process of GA in the entire process is discussed in detail. In addition, the catalytic performance of porous GA on AP was studied. Thermogravimetry (TG)/differential scanning calorimetry (DSC) research results show that after GA and AP are mixed, the high-temperature exothermic peak is advanced from 441 to 345 °C , and the heat released △H is increased from 205 to 720 J/g. Three-dimensional porous GA is hoped to be a promising catalyst for AP thermal decomposition.
