“…Importantly, the HEDM decomposition behavior could be mostly determined by the active sites of the catalyst. Porous carbon frameworks loaded with Ni and Fe nanoparticles have obvious effects on the fast decomposition of CL-20 33 and AP, 34,35 which also shed light on the probing of the porous 2H-phase MoS 2 . This paper reveals excellent decomposition behavior and safety performance of two typical high-nitrogen energetic compounds (NTO and TKX-50) using porous MoS 2 nanosheets.…”

“…[1][2][3][4] In composite solid propellants, the typical oxidizer is ammonium perchlorate (AP) which provides the oxygen needed and gives out high energy to promote the combustion of composite solid propellants. [5][6][7] Recently, the thermal decomposition of AP has been paid close attention because of widespread applications in solid propellants which are composite. More importantly, the thermal decomposition of AP directly influences combustion behavior of propellants which are solid in nature which composite.…”

Reducing the thermal decomposition temperature of ammonium perchlorate (AP) is of great significance for its application in composite solid propellants. Here, CuO/SiO 2 nanocomposites were prepared using wet impregnation method with Cu (CH 3 COO) 2 ÁH 2 O as copper precursor followed by a calcination process. The structure and morphology of the prepared samples were characterized with the help of scanning electron microscopy (SEM), Xray diffraction (XRD), and Brunauer-Emmett-Teller (BET), respectively. The outcomes revealed the uniform dispersion of CuO were throughout silica aerogels to prevent agglomeration efficiently. Moreover, results from differential scanning calorimeter (DSC) showed that CuO/SiO 2 nanocomposites could effectively enhance AP's thermal decomposition since they have large specific surface areas, many active reduction sites, and good adsorption capacity. As expected, the high decomposition temperature of AP was reduced from 418.7 C to 341.8 C when the amount of CuO/SiO 2 nanocomposites was 4 wt%. Therefore, silica aerogels were good catalyst supports of CuO for AP's thermal decomposition. It can bring about new potential for application of new materials in high energy as AP-based catalysts propellants which are solid in nature.

“…LiF is also a well‐known inhibitor of AP decomposition which decreases the burning rate of AP through the formation of NH 4 F in the eutectic mixture of LiF and NH 4 ClO 4 [19]. The high catalytic effect of fullerenes and carbon black as pure organic compounds on the thermal decomposition of AP has also been investigated [25]. The catalytic activity of Viton A and fibrous nitrocellulose on AP decomposition was investigated and effects of different parameters on this process were stuided [26].…”

For the first time, the thermal decomposition behavior of heterogeneous mixtures of ammonium perchlorate (AP) with two organic additives – 4, 4’‐Bipyridine, and biphenyl – were investigated. The heterogeneous mixtures of the additives and ammonium perchlorate were prepared by dissolving 1, 2, 3, 4, and 5 mg of the organic additives and 100 mg ammonium perchlorate in 2 ml of methanol as solvent. After that, the thermal decomposition behavior of prepared solid heterogeneous mixtures was monitored by thermogravimetry analysis, differential scanning calorimetry, and mass spectrometry analysis. The effect of the 4, 4’‐Bipyridine on thermal decomposition of AP enhanced the released heat from 479 to 1842 J g−1 and produced a decrease of decomposition temperature from 433 °C to 308 °C while the thermal decomposition of AP in the presence of biphenyl did not change as dramatically as it did with 4, 4’‐Bipyridine. With biphenyl, the decomposition temperature was found to be similar to that of pure AP and the evolved heat was about 718 J g−1. The gaseous products of decomposition of 4, 4’‐Bipyridine /ammonium perchlorate were monitored by mass spectrometric analysis. The main evolved decomposition gases of pure AP are N2O, O2, Cl2, ClO, ClO2, ClO3, HClO4, and HCl, while the major gaseous products of the 5:100 (w/w) mixture of 4, 4’‐Bipyridine with AP were detected as N2, NO, N2O, O2, Cl2, ClO, ClO2, ClO3, HClO4, HCl and 4, 4’‐Bipyridine. The change in the composition of volatile products indicates a change in the mechanism of AP decomposition from proton transfer to electron transfer in the presence of 4, 4’‐Bipyridine.
