Title Preparation of CuO/RGO nanocomposites and its effects on the thermal decomposition performance of ammonium perchlorate
Abstract
In this article，nano-sided CuO have been successfully prepared in large-scale by mechanical grinding method, then were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results revealed that the nano-sized CuO is semi-spherical and homogeneous with a fairly uniform size of 17 nm and the study on the catalytic ability of the thermal decomposition of AP showed that nano-sized CuO could be a kind of effective additive for accelerating the thermal decomposition of ammonium perchlorate (AP).Furthermore, the more nano-sized CuO added in AP, the more clear the decomposition peak of high temperature and low temperature decomposition moved up.The graphene(RGO) was synthesized in a hydrothermal method, using NaOH as reducing agent and the transparent RGO obtained had a great thermal stability, effectively removed the oxygen-containing functional groups.This method was non-toxic and the reaction time was shorter.CuO/RGO nanocomposites were acquired through blending and research on its catalytic properties for AP indicated that the catalytic ability of CuO / RGO nanocomposites on AP were more effective than single RGO and nanosized-CuO.
