摘要/Abstract

摘要： 采用HLG-5型纳米化粉碎机批量制备了纳米CuO。通过X射线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)对CuO颗粒的结构、大小及形貌进行了表征，并采用差示扫描量热仪(DSC)分别研究了纳米CuO的含量为1%，1.5%，2%，2.5%，4%对不同粒度AP的热分解性能的影响。结果表明，制备的CuO颗粒大小约为17nm，为单斜晶系，呈类球形。2%含量的纳米CuO对AP具有更好的催化性能，可使64μm，6μm，1μm AP的高温分解峰分别降低83.0℃，81℃，55.4℃；表观分解热分别增加880J/g，617J/g，391J/g；反应速度常数提高数倍。

Abstract: Nano-CuO have been successfully prepared in large-scale using the HLG-5 grinder. The microstructure，size and morphology of CuO particles were characterized by X-ray diffraction (XRD)，scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The catalytic effects of nano-CuO with mass fraction of 1%，1.5%，2%，2.5% and 4%，respectively，on thermal decomposition of AP with different size were investigated by DSC. The results show that nano-CuO could be indexed as pure monoclinic and have a semi-spherical morphology with a fairly uniform size of 17nm. Furthermore，the nano-CuO have the optimal catalytic effect at a mass fraction of 2%，and the peak values of high temperature decomposition of 64μm，6μm，and 1μm AP decreased by 83.0℃，81℃ and 55.4℃，respectively. The apparent thermal decomposition of 64μm，6μm，and 1μm AP increased by 880J/g，617J/g and 391J/g，respectively，and the reaction rate constant of AP also increased by several times.
