【摘要】：采用HLG-5型纳米化粉碎机批量制备了纳米Cu O。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Cu O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Cu O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Cu O颗粒大小约为17nm,为单斜晶系,呈类球形。2%含量的纳米Cu O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 Cu O was prepared by HLG-5 type nanoscale pulverizer. By means of X ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) structure, size and morphology of Cu O particles were characterized by differential scanning calorimetry (DSC) respectively on the content of nano Cu O was 1%, 1.5%, 2%, 2.5%. Effect of decomposition performance of 4% different granularity of AP hot. The results show that the size of the prepared Cu O particles is about 17nm, which is a monoclinic system with a spherical shape. 2%, the content of nano Cu O has better catalytic performance for AP. It can make the decomposition peaks of 64, m, 6, m and 1 m AP decrease by 83, 81, 55.4, respectively. The apparent decomposition heat increases 880J/g, 617J/g and 391J/g respectively, and the reaction rate constant increases by several times.

【正文快照】： 1引言作为一种典型的半导体材料,Cu O具有狭窄的能隙(~1.21e V),使其在催化领域备受关注[1~3]。Cu O作为燃速催化剂在固体火箭推进剂中的应用,已经引起研究者的广泛研究[4~7]。近年来,Cu O对AP的催化效果的研究国内外已有不少报道,张智宏[8]等制备的纳米Cu O可使AP的高温分解
