Summary: Transition metal carbonitrides (MXenes) have special structures and show promising catalytic effects. However, the catalytic mechanisms of MXenes in the thermal decomposition of ammonium perchlorate (AP) have not been extensively studied. In this study, the catalytic properties of Ti2CTx for AP thermal decomposition were investigated through various experiments. The results showed that Ti2CTx can decrease the high-temperature decomposition of AP and increase the decomposition heat. Moreover, the Ti2CTx nanosheets can adsorb gaseous products and react with them in-situ, generating anatase-TiO2 and carbon layers that further catalyze the thermal decomposition of AP.

Summary: MXene-supported CuO nanocomposites were synthesized without using any chemical modifiers via an ice-crystal templating method. The study showed that the MCNs as catalysts could significantly decrease the high temperature decomposition temperature of AP and increase the exothermic heat. The synergistic effect between MXene nanosheets and CuO nanoparticles contributed to the high catalytic activity of MCNs for AP thermal decomposition.

Summary: The combustion behavior of ammonium perchlorate (AP) can be influenced by the addition of catalyst, as well as the combination mode of catalyst and AP. This study investigated different catalysts and AP prepared by mechanical mixing and spray drying composite. The results showed that the spray drying composites exhibited better catalytic performance on the thermal decomposition of AP compared to mechanical mixing. All catalysts passivated the low-temperature decomposition process of AP and catalyzed the high-temperature decomposition process.

Summary: In the past decade, the scientific community has extensively studied the decomposition of ammonium perchlorate (AP). This research aims to investigate the effect of nanothermite on the thermal decomposition of AP. MgAl-PTFE nanothermite was mechanically activated through arrested reactive milling, coated with potassium perchlorate (KP), and characterized. The results showed that the phase compositions remained unchanged and the presence of nanothermites promoted the thermal decomposition process of AP by reducing the activation energy by about 6%.

Summary: Five nanometal catalysts (Fe, Co, Ni, Cu, and Zn) were prepared and evaluated for their catalytic activity in the thermal decomposition of ammonium perchlorate (AP). The addition of 0.5% each of Zn, Cu, Ni, Co, and Fe lowered the peak temperature of high-temperature decomposition by 93, 55, 47, 15, and 13 degrees C, respectively. The highest heat energy release of 1910 J g(-1) was achieved with 0.5% Cu. Copper nanometal powder emerged as the most promising catalyst for AP thermal decomposition, improving burn rate and reducing mass penalties.
