| 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4.5h时分别合成了直径为100-200nm和1μm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100-200nm和1μm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. |
