摘要： 以聚乙烯吡咯烷酮(PVP)为添加剂, 利用溶剂热法合成了Cu2O微球. 考察了PVP用量以及反应温度对产物形貌的影响, 并在反应时间为2.5 与4.5 h 时分别合成了直径为100-200 nm和1 μm的Cu2O微球. 同时,利用差热分析(DTA)技术考察了不同直径的Cu2O微球对高氯酸铵(AP)热分解的催化效果, 结果表明: 添加2%(w)的直径为100-200 nm和1 μm的Cu2O微球使得AP 的高温分解温度分别降低了116 和118 °C, AP在低温阶段的分解量也明显提高.

Abstract: Cu2O micro-spheres were fabricated by a solvothermal method using poly vinylpyrrolidone (PVP) as an additive. The influences of PVP dosage and reaction temperature on the morphologies of the products were investigated. Cu2O micro-spheres with diameters of 100-200 nm and about 1 μm were synthesized with reaction time of 2.5 and 4.5 h, respectively. Meanwhile, differential thermal analysis (DTA) was used to determine the catalytic performance of these Cu2O micro-spheres with different diameters for thermal decomposition of ammonium perchlorate (AP). Adding 2% (w) Cu2O micro-spheres with diameters of 100-200 nm and about 1 μm into AP decreased the maximum temperature of AP decomposition by 116 and 118 °C, respectively, and increased the amount of AP decomposed at lower temperature.

Key words: Cu2O micro-spheres, Solvent-thermal synthesis, Ammonium perchlorate, Thermal decomposition
