Abstract Achieving a synergistic, rapid, and concentrated energy release process of ammonium perchlorate (AP) is vital significance for boosting the thrust composite solid propellants. However, conventional catalytic promoters often exhibit suboptimal kinetics due to inefficient utilization active sites. Herein, atomically dispersed Cu‐coordinated covalent organic frameworks (COFs)‐based are reported, decorating with energetic anion groups. The highly accessible single Cu sites confined in COFs significantly contribute raid AP, yielding sharply narrowed decomposition peak at 341.3 °C width only 9 °C. This performance markedly superior exothermic raw AP (410.3 30 °C). Additionally, COF promoter considerably increased output via collaboratively promoting chemical its own decomposition. Correlating situ spectroscopies theoretical calculations reveals that incorporated anionic groups effectively modulate local electronic structure alteration promotes key step cleavage Cl─O bonds intermediates produce reactive oxygen species also boosts oxidation NH 3 high‐valence nitrogen oxides, thereby accelerating combustion reaction kinetic.

Adding burning-rate catalysts (BRCs) is highly effective for enhancing ammonium perchlorate (AP) thermal decomposition. To mitigate BRCs’ agglomeration and enhance their catalytic activity AP pyrolysis, five metal carbonyl compounds (Mo(CO)6, Cr(CO)6, W(CO)6, Fe2(CO)9, Mn2(CO)10) were refined into oxidized carbon nanotube (CNTs) cavities, respectively, by ultrasonication. The structures of the as-prepared nanocomposites examined with TEM, SEM, XPS, Raman, etc., confirming successful filling compounds. Electrochemical studies revealed that Mo(CO)6@CNTs(N1) exhibited an enhanced electron transfer rate superior electrocatalytic performance compared to CNTs(N1). Their evaluated DSC showed 5 wt.% exhibits best effect, increasing heat release 2904.63 J·g-1, advancing its peak temperature 80.6 oC, decreasing activation energy 100.45 KJ·mol-1. degradation mechanism catalyzed was probed through TG-FTIR-MS, in-situ solid FTIR, theoretical calculations. investigations suggested promoter in generates nanotubes-confined MoO3 nanoparticles featuring numerous Lewis Brønsted acidic sites, which not only improves NH3 adsorption but also enhances accelerates O2 conversion O2-, thereby facilitating pyrolysis. Finally, a plausible decomposition postulated.
