“…Indeed, the incorporation of 2 wt.‐% of sphere‐like CuO NPs was found to lower the temperature of the thermal decomposition and the Ea by 115 °C and 111 kJ · mol –1 , respectively. [ 26 ] Likewise, the physical mixing of AP with CuO chrysalis‐like morphology at a ratio of 98–2 wt.‐% lead to a significant decrease of the HTD by 85 °C. [ 27 ] whereas CuO/AP mixture prepared following solvent and non‐solvent process diminished the HTD temperature by 90 °C, thus confirming the efficiency of this latter, which improved the catalytic effect of CuO.…”

In the present work, a green synthesis of copper oxide nanoparticles (CuO NPs) has been performed through a precipitation method using three different copper precursors and sylvestrys leaf extract as a capping agent. Morphology and structure of the obtained CuO NPs were confirmed by X‐ray diffraction (XRD), ultraviolet‐visible (UV/Vis), Fourier transform infrared (FT‐IR) and Raman spectroscopy, as well as scanning electron microscopy (SEM). Moreover, their thermal behavior and catalytic performance were studied using thermogravimetry (TG) and differential scanning calorimetry (DSC). Four isoconversional kinetic methods have been applied to the DSC data obtained at different heating rates in order to determine the kinetic triplets. The results showed that the introduction of CuO NPs has noticeably lowered the thermal decomposition temperature by 91.7, 89.9, and 83.0 °C, and increased the exothermic enthalpy by 1053, 832, and 962 J·g–1 for AP‐CuO‐S, AP‐CuO‐N, and AP‐CuO‐Cl, respectively. Furthermore, CuO NPs were found to reduce the activation energy of AP decomposition. Besides that, ammonium perchlorate decomposes following different reaction models g(α), depending on the decomposition stage and the addition of CuO NPs. These results indicate further that the green synthesized CuO nanoparticles are promising ballistic modifiers for composite solid propellants.

Nanometer triaminoguanidine nitrate (TAGN) with mean size of 218.7 nm was fabricated, and its structures were characterized by scanning electron microscopy, X-ray diffraction, IR, and X-ray photoelectron spectroscopy analyses. As an energetic accelerator for thermal decomposition of ammonium perchlorate (AP) and ammonium nitrate (AN), 10% nano TAGN blended with AP and AN, and samples “[90% AP + 10% (nano TAGN)]” and “[90% AN + 10% (nano TAGN)]” were obtained, respectively. Differential scanning calorimetry (DSC) analyses were employed to investigate the decomposition kinetics and thermodynamics of the samples. The results indicated that [90% AP + 10% (nano TAGN)] presented a higher activation energy (152.34 kJ mol –1 ) than pure AP (117.21 kJ mol –1 ) and [90% AN + 10% (nano TAGN)] possessed a lower activation energy (147.51 kJ mol –1 ) than pure AN (161.40 kJ mol –1 ). All activation free energies (Δ G ≠ ) were positive values. This means that activation of the molecules was not a spontaneous process. The decomposition peak temperature of AP decreased from 478.5 °C (for pure AP) to 287.2 °C (for [90% AP + 10% (nano TAGN)]). The decomposition peak of AN also advanced via doping with nano TAGN. Using DSC-IR analysis, the decomposition products of nano TAGN, pure AP, [90% AP + 10% (nano TAGN)], pure AN, and [90% AN + 10% (nano TAGN)] were investigated, and their decomposition mechanisms were proposed. The key factors, i.e., the formation of hydrazine in the decomposition of nano TAGN, were speculated, which substantially promoted the consumption of HNO 3 , HClO 4 , and their decomposition products in kinetics. Additionally, the energy performances of AP- and AN-based propellants doping with TAGN were evaluated. It is disclosed that the introduction of TAGN would not result in improvement in the energy performance of propellants, but due to its energetic property and high hydrogen content, proper introduction of TAGN will not reduce the energy performance of propellants in a large degree compared with the introduction of inert catalysts.

This study focused on the kinetics and mechanisms of the thermal decomposition of Cu(OH)2 as a potential processing route to produce CuO nanoparticles. The physico-geometric reaction behaviors were studied using available physicochemical techniques and microscopic observation. The kinetic modeling of the reaction process to produce CuO nanoparticles was examined via the kinetic analysis of the mass-loss data recorded under different heating conditions. The reaction exhibited specific physico-geometric kinetic characteristics, including an evident induction period, a subsequent sigmoidal mass-loss behavior under isothermal conditions, and a long-lasting reaction tail under linearly increasing temperature conditions. During the first mass-loss step characterized by the sigmoidal mass-loss behavior, the crystallite size of the produced CuO was constant, and the specific surface area increased systematically. The second mass-loss step during the reaction tail was accompanied by the crystal growth of CuO. Therefore, the end of the first mass-loss step was the most efficient reaction stage to obtain CuO nanoparticles. The overall kinetic process that reaches this reaction stage was successfully demonstrated as consecutive physico-geometric processes comprising the induction period, surface reaction, and one-dimensional phase boundary-controlled reaction, providing the kinetic parameters for each component step.
