| 摘 要： | 采用油/水界面间的化学共沉淀反应制备了纳米CoFe2O4前驱体,并运用差示扫描量热仪(DSC)研究了纳米CoFe2O4前驱体的热分解特性,利用XRD,TEM对不同温度煅烧生成的纳米CoFe2O4进行了表征,采用DSC研究了不同含量纳米CoFe2O4对高氯酸铵(AP)热分解的催化影响.结果表明:300 ℃左右尖晶石型CoFe2O4已开始形成,随温度升高,晶化趋于完全,而粒子的晶粒度逐渐增大,500 ℃下可获得粒径较小、结晶良好的尖晶石型纳米CoFe2O4;在AP中添加纳米CoFe2O4后,可使AP在较低温度下发生热分解,并且对AP热分解的催化作用随其含量增加而增强.

| Abstract: | The precursor of CoFe2O4 nanoparticles was prepared by in situ chemical precipitation at the oil-water interface,and its thermal decomposition characteristics were studied by DSC.The as-prepared CoFe2O4 nanoparticles calcined at different temperatures were characterized by XRD and TEM,and the effects of catalysis of the CoFe2O4 nanoparticles with different contents on the ammonium perchlorate decomposition were studied by DSC.Results show that CoFe2O4 nanoparticles with spinel structure initially are formed... |
