The catalytic decomposition of ammonium perchlorate (AP) by magnesium oxide (MgO) nanoflakes (NFs) with hexagonal and quasi-circular structures was investigated. MgO NFs were synthesized by hydrothermal process and characterized by TEM, FESEM, XRD and BET. Catalytic activities of MgO NFs were researched via TG-DSC analysis. After MgO NFs were added to AP, the temperature of AP decomposition rose in the first exothermic stage and reduced in the second exothermic stage. The catalytic performances of MgO NFs depended on the mass fraction in AP. MgO NFs with 2% (wt%) addition exhibited the highest catalytic efficiency. The kinetics of AP decomposition was studied by using Kissinger plot method. The results showed that MgO NFs had obvious influences on the kinetic parameters in the different stages of AP thermal decomposition.

高氯酸铵在氧化镁纳米片上的催化分解及动力学分析

研究了具有六边形和准圆形结构的氧化镁 (MgO) 纳米薄片 (NFs) 对高氯酸铵 (AP) 的催化分解。MgO NFs通过水热法合成,并通过TEM、FESEM、XRD和BET表征。通过TG-DSC分析研究了MgO NFs的催化活性。将MgO NFs加入AP后,AP分解温度在第一放热阶段升高,在第二放热阶段降低。MgO NFs 的催化性能取决于 AP 中的质量分数。添加 2% (wt%) 的 MgO NFs 表现出最高的催化效率。使用 Kissinger 绘图方法研究了 AP 分解的动力学。结果表明,MgO NFs对AP热分解不同阶段的动力学参数有明显影响。
