摘要
采用DTA表征了过渡金属氧化物(TMO)对高氯酸铵(AP)的热分解催化性能,结果表明:单组分及二元复合过渡金属氧化物对AP的催化作用顺序分别为Co2O3>CuO>Fe2O3和Fe2O3／Co2O3>CuO／Co2O3>Fe2O3／CuO,二元复合TMO催化作用表现出的三种协同效应,取决于复合物的组合及混合比。通过AP高温分解峰温随复合物中某一组分的质量百分含量变化曲线,快速地找出最佳的TMO组合为Fe2O3:Co2O3=1:3。
The catalytic effects of superfine transition metal oxides Fe2 O3, CuO and Co2 O3 on the thermal decomposition of ammonium perchlorate was studied by differential thermal analysis. Results show that both the single transition metal oxide and the composite ones have catalytic effects on the thermal decomposition of AP (Co2O3 > CuO > Fe2O3 and Fe2O3/Co2O3 > CuO/Co2O3 > Fe2O3/CuO in sequence) , and the catalytic behavior of the composite transition metal oxides ( TMOs) showed three cooperative effects, which depended on the combination and suitable mixing proportion of TMOs. From the curves of the temperature change of the higher exothermic peak of AP decomposition with the content of one of the composite TMOs, the optimum combination (Fe2O3: Co2O3 =1: 3)can be found.
