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.
