利用化学还原法制备了纳米CO-B非晶态合金,并用透射电镜、X射线衍射、差示扫描量热和N2吸附表面积测试等技术对样品进行了表征.运用差热分析研究了纳米CO-B非晶态合金对高氯酸铵(AP)分解的催化性能.结果表明,加入CO-B非晶态合金后AP的高低温放热峰相连,合并成一个高而大的放热峰,且峰温有很大程度的降低,这说明纳米CO-B非晶态合金对AP热分解有很好的催化活性.同时,CO-B非晶态合金能使AP的表观分解热显著增大.
The nano-CO-B amorphous alloy was prepared by chemical reduction method, and the samples were characterized by transmission electron microscopy, X-ray diffraction, differential scanning calorimetry and N2 adsorption surface area testing.Using differential thermal analysis, B amorphous alloy on the decomposition of ammonium perchlorate (AP) .The results show that after the addition of CO-B amorphous alloy AP high and low temperature exothermic peak connected to merge into a high and large exothermic peak, And the peak temperature decreased to a great extent, indicating that nano-CO-B amorphous alloy has good catalytic activity for AP thermal decomposition.At the same time, CO-B amorphous alloy can significantly increase AP apparent heat of decomposition Big.
