Abstract: CuI was fabricated by an elementdirectreaction route at 40 ℃ in ethylene glycol as solvent, copper powder as oxidant, iodine as reducing agent. The product was characterised by Xray diffraction (XRD) and scanning electron microscopy (SEM). The catalytic activity was reviewed as a catalyst in the thermal decomposition of ammonium perchlorate. The result show that CuI nanoparticles is sheet strcture, its average diameter is about 99 nm at 40 ℃ and its average diameter is about 87 nm at 60 ℃. Addition of CuI in ammonium perchlorate (AP) led to a significant reduction of low decomposition temperature and high decomposition temperature of AP, two decomposition temperture peaks incorporate a decomposition temperture peak, and the temperature of the peak at the high decomposition temperature stage is therefore decreased by 111 ℃. 

摘要： 在4 0℃条件下, 以铜粉为还原剂、 碘单质为氧化剂、 乙二醇为溶剂, 进行单质之间的反应, 制备了碘
化亚铜。利用XR D和S EM 对产物进行了表征, 并对合成的碘化亚铜进行了催化分解高氯酸铵反应的研究, 探讨了
其催化性能。实验结果表明, 碘化亚铜为片状结构, 反应温度为4 0℃的产物粒径为9 9n m; 反应温度为6 0℃的产物
粒径为8 7n m。碘化亚铜的加入降低了高氯酸铵的低温、 高温的分解温度, 使得这两部分的分解温度合二为一, 高温
分解温度提前了1 1 1℃。
