Understanding the synergistically enhanced thermocatalytic decomposition of ammonium perchlorate using cobalt nanoparticle-embedded nitrogen-doped graphitized carbon

“…Moreover, the thermal decomposition kinetics of AP can significantly affect the combustion behavior of CSPs 2 . In general, lower hightemperature decomposition (HTD) temperature and higher heat release of AP can achieve the increase of the combustion rate, high specific impulse, and low-pressure exponent of CSPs 3,4 . In order to enhance the combustion performance of CSPs, the catalytic thermal decomposition of AP was extensively studied via utilizing the catalytic activity of nano metals [5][6][7][8] and nano metal oxides [9][10][11][12][13][14] .…”

[9][10][11][12][13][14] In contrast to nano metal oxides, the corresponding nano metals have a better ability to catalyze the thermal decomposition of AP, [15][16][17] mainly because of its special electronic effect of lattice defects 18,19 and oxidation exothermic enhancement effect.…”

Exploring the Roles of ZIF-67 as an Energetic Additive in the Thermal Decomposition of Ammonium Perchlorate

“…Composite solid propellants (CSPs), composed of oxidants, additives, binder, and fuels, are power producers widely used in aviation, space flight, and missiles. , Among these ingredients, oxidants usually occupy more than a half of CSPs and greatly affect the performance of CSPs. Ammonium perchlorate (AP) is a common oxidant in CSPs, , and its thermal decomposition properties can greatly influence the combustion performance of CSPs. , It is reported that AP-based CSPs can display a high specific impulse, low-pressure exponent, and fast burning rate by increasing the heat release and decreasing the decomposition temperature of AP. − Therefore, promoting the thermal decomposition of AP can enhance the combustion performance of CSPs.…”
