The data of the article "Regulating Thermal Decomposition of Ammonium Perchlorate by Fe-based Functional Coordination Polymers"

The pressure exponent is 0.571, significantly lower than that of conventional catalyzed systems (typically>0.7). This improvement results from optimized interfacial interactions between Fe-CPs@AP and the propellant matrix, promoting the in situ formation of uniformly dispersed metal oxide nanoparticles during AP decomposition and maximizing catalytic activity. Mechanistic and density functional theory studies indicate that Fe-containing species serve as catalytic mediators.

They enhance electron transport in the low-temperature decomposition phase, optimize electron transfer between ClO4– and NH4+, promote oxygen species adsorption, increase thermal energy release at high temperatures, and improve AP decomposition efficiency. This work tackles issues such as AP’s hygroscopicity, particle aggregation, and pressure sensitivity, offering theoretical and practical support for developing high-performance combustion propellants.
