With the development of aerospace science and technology, requirements for propellants are increasingly high. The thermal decomposition behavior of ammonium perchlorate (AP) directly influences the combustion performance of composite solid propellants. Catalysts play an important role in improving the thermal decomposition behavior of AP. In this study, three novel metal-organic frameworks (MOFs) were prepared using a straightforward method, namely Co[N(CN)₂]₂ (1; nitrogen content: 43.5%), Cu[N(CN)₂]₂ (2; nitrogen content: 43.0%), and Pb[N(CN)₂]₂ (3; nitrogen content: 24.8%). Their crystal structures were characterized and analyzed through single-crystal X-ray diffraction, forming interesting three-dimensional architectures. Moreover, derived composite catalysts under air (4, 6, and 8) or nitrogen (5, 7, and 9) atmosphere were generated by heating MOFs 1, 2, and 3–500 ​°C at a heating rate of 5 ​°C·min⁻¹. The derived catalyst 4 exhibited the best performance. It reduced the decomposition peak temperature of AP by 81.9 ​°C, increased the heat release from 785 ​kJ·g⁻¹ to 1232 ​kJ·g⁻¹, and decreased the apparent activation energy (E_a) of AP from 223 ​kJ·mol⁻¹ to 145 ​kJ·mol⁻¹.

随着航天科技的发展，对推进剂的要求越来越高。高氯酸铵（AP）的热分解行为直接影响复合固体推进剂的燃烧性能。催化剂在改善 AP 的热分解行为方面起着重要作用。在这项研究中，使用简单的方法制备了三种新型金属有机框架 (MOF)，即 Co[N(CN) ₂ ] ₂ ( 1；氮含量：43.5%)、Cu[N(CN) ₂ ] ₂ ( 2 ; 含氮量43.0%), Pb[N(CN) ₂ ] ₂ ( 3; 氮含量：24.8%）。通过单晶 X 射线衍射对它们的晶体结构进行了表征和分析，形成了有趣的三维结构。此外，在空气（ 4、6和8）或氮气（5、7和9 ）气氛下，通过以 5 ° C的加热速率加热MOF 1、2和3 –500 °C ，生成衍生复合催化剂C·min ^-1。衍生催化剂4表现出最好的性能。将 AP 的分解峰值温度降低了 81.9 °C，将热释放从 785 kJ·g ^−1增加到 1232 kJ·g ⁻¹ ，并将AP 的表观活化能( E _{a ) 从 223 kJ·mol} ⁻¹降低到 145 kJ·mol ⁻¹。
