摘要

已有研究发现，金属掺杂碳气凝胶可以有效催化高氯酸铵（AP）的热分解行为。本研究通过凝胶化和碳化的关键步骤，采用双金属MOF （HMOF）前驱体法制备了一种掺杂Mn和Co的碳气凝胶催化剂，并对其对AP的热催化机理进行了详细的研究。结果表明，Mn/Co@C气凝胶的催化性能优于单金属掺杂碳催化剂。当添加量为2%，升温速率为10℃/min时，AP的分解峰温度提高约115℃，热分解活化能降低至147 kJ·mol-1。

Coordination-Driven Directional Construction of Mn/Co@Carbon Aerogels and Thermal Catalysis of Ammonium Perchlorate

Previous studies have found that metal-doped carbon aerogels can effectively catalyze the thermal decomposition behavior of ammonium perchlorate (AP). In this study, a kind of carbon aerogel catalyst doped with Mn and Co was prepared by the bimetallic MOF (HMOF) precursor method through the key steps of gel and carbonization, and its thermal catalytic mechanism for AP was studied in detail. The results showed that Mn/Co@C aerogels had better catalytic performance than the monometal-doped carbon catalyst. When the addition amount was 2%, the heating rate was 10 °C/min, the decomposition peak temperature of AP was advanced by about 115 °C, and the thermal decomposition activation energy was reduced to 147 kJ·mol^–1.
