“…AP thermal decomposition depends on physical and chemical interaction among decomposition products [8,9]. AP decomposition could be altered via controlled morphological properties, as well as the integration of advanced catalyst particles such as ferric oxide, and copper oxide [10][11][12][13][14]. Ferric oxide is the common catalyst to boost AP decomposition with positive impact on its energetic power [15].…”

Ferric oxide is a universal catalyst. Reactive metal fuel can act as a high energy dense material such as aluminum which is marked by the very high gravimetric and volumetric heat output. This manuscript reports on the fabrication of colloidal ferric oxide nanoparticles of 5 nm. Colloidal ferric oxide/aluminum nanothermite mixture was integrated into ammonium percholorate (AP) via the coprecipitation technique. The shape and particles size of the prepared nano ferric oxide were investigated by using TEM instrument. Uniform dispersion of Al/Fe2O3 in the ammonium perchlorate matrix was verified using EDAX instrument. Nanothermite particles offered enhanced AP decomposition enthalpy by 120 % using DSC. Nanothermite colloid offered a decrease in AP activation energy by 51 and 40 % using Friedman and Ozawa models respectively. AP decomposition mechanism was reported to go through three consequent mechanisms including the first order mechanism, two-dimensional diffusion reactions, and one- dimensional diffusion mechanism according to extent of reacted fraction (α) of 0-0.25, 0.3-0.6, and 0.6-0.9 respectively. The results show that the catalyzing ability of the nanothermites was confirmed and has shown a superior effect on the AP energetic system.

“…In the AP breakdown process, metal oxide acts as a catalyst that is heterogeneous, Increasing the rate of ammonia/perchloric acid breakdown on the catalyst surface [9,10]. The active sites of a heterogeneous catalyst are the most important factor [11], particle size, and surface area [12][13][14]. to increase the action of a catalyst, it must have a big surface area and a small particle size.…”

The universal burning rate modifier used in composite solid propellants is copper chromite. The fabrication of copper chromite nanoparticles (CCNs) is highly appreciated; as superior performance could be accomplished. This research looks at how copper chromite nanoparticles can be made in a sustainable way using hydrothermal processing. Mono-dispersed particles with a medium particle size of 12 nm were seen in TEM micrographs. The XRD diffractogram revealed a crystalline structure. The co-precipitation approach was used to incorporate CCNs into ammonium perchlorate (AP). Differential scanning calorimetry (DSC) and thermal gravimetric analysis were used to analyze the activity of catalysis in CCNs on AP breakdown (TGA). The enthalpy of AP breakdown was enhanced from 742 J/g to 1391 J/g. CCNs caused the Peak of high-temperature decomposition shift toward lower temperatures, resulting in the overlapping of the two peaks into a single peak. At 244 °C, CCNs showed a decrease in AP endothermic phase transition. These characteristics could ensure high-burning-rate catalyzed decomposition processes.

Nickel nanoparticles with partially filled d-shell could offer advanced catalytic performance; to common solid propellant catalysts (ferric oxide). This study reports on the facile fabrication of nickel and ferric oxide catalysts of 10 nm, and 5 nm particle sizes respectively. Fabricated particles were re-dispersed in organic solvent and effectively integrated into ammonium percholorate (AP). Elemental mapping confirmed uniform particle dispersion into APC. The catalytic efficiency of nickel was evaluated to Fe2O3 particles using DSC and TGA. AP demonstrated endothermic crystallographic phase change at 242 0C, with subsequent two exothermic decomposition reactions. Nickel demonstrated decrease in endothermic phase change by 49 % compared with 39 % for ferric oxide; this action means high catalytic activity with low activation energy. Whereas AP demonstrated total heat release of 742 J/g; nickel offered enhanced heat output by 89 % compared with 57 % for ferric oxide. The two main decomposition peaks were merged into single peak. Nickel demonstrated decrease in main decomposition temperature by 105 oC compared with 62 oC for ferric oxide. This manuscript shaded the light on nickel as novel emergent nanocatalyst with superior performance for advanced energetic systems.
