“…For comparison, AP‐nAl and AP‐nAl‐CuO composites were also measured. The mass ratio of AP: nAl: catalyst was 15:5:1 . As shown in Figure , all the above three composites burned fast and displayed larger and brighter flames in air than in N 2 atmosphere because air environment could provide more O 2 for AP‐nAl, AP‐nAl‐CuO and AP‐nAl‐CuO/MoS 2 composites sufficient combustion.…”

“…Therefore, highly efficient decomposition of AP at lower temperature with higher heat release is of importance for obtaining more powerful solid fuel rockets . Various transition metal oxides are developed to catalyze AP decomposition, such as Fe 2 O 3 , CuO, MnO 2 , MgO, NiO, Co 2 O 3 , and ZnO . Most of these transition metal oxides are p‐type semiconductors, among which CuO is the most investigated one.…”

In this report, CuO/MoS2 composites were successfully prepared by the hydrothermal method where nano‐sized CuO was uniformly distributed on the surface of hierarchical MoS2 substrates (CuO/MoS2 composites). Their physicochemical properties and catalytic performance in ammonium perchlorate (AP) decomposition were investigated and characterized by XRD, SEM, TEM, BET, XPS, TG/DSC and combustion measurement. The results showed that it could decrease AP decomposition temperature at high decomposition stage from 416.5 °C to 323.5 °C and increase the heat release from 378 J/g (pure AP) to 1340 J/g (AP with catalysts), which was better than pure CuO nanoparticles (345.5 °C and 1046 J/g). Meanwhile, it showed excellent performance in combustion reaction either in N2 or air atmosphere. The results obtained by photocurrent spectra, photoluminescence spectra and time‐resolved fluorescence emission spectra indicated that loading CuO mediated the generation rate and combination rate of electrons and holes, thus tuning the catalytic performance on AP decomposition. This study proved that employing the supports that can synergistically interact with CuO is an efficient strategy to enhance the catalytic performance of CuO.

In this study, three energetic complexes, namely Cu(1‐MIM)2(N3)2 (1) (1‐MIM=1‐methylimidazole), [Cu(1‐VIM)2(N3)2]n (2) (1‐VIM=1‐vinylimidazole), and Cu(2‐MIM)3(N3)2 (3) (2‐MIM=2‐methylimidazole), were synthesized via a simple and mild method. The complexes were characterized by single‐crystal X‐Ray diffraction, Fourier transform infrared (FTIR) spectroscopy, and elemental analysis. The thermal behavior and sensitivity of the complexes were analyzed by DSC, TG, and BAM methods, and their catalytic performances with respect to AP (ammonium perchlorate), CL‐20 (hexanitrohexaazaisowurtzitane), and BNFFO (3,4‐dinitrofurazanfuroxan) thermal decomposition were studied by differential scanning calorimetry (DSC). The obtained results indicate that complex 1 exhibits the best catalytic performance for AP thermal decomposition, as it reduces the decomposition (high‐temperature) peak temperature by 101.0 °C compared to pure AP. Moreover, this complex alters the shape of the decomposition peak, which suggests that it speeds up the decomposition process and renders it more intense. In terms of CL‐20 and BNFFO thermal decomposition, complex 3 shows the best catalytic performance, and it reduces the peak decomposition temperatures by 18.4 and 108.2 °C, respectively, compared to the pure samples. The activation energies of the AP/complex, CL‐20/complex, and BNFFO/complex mixtures were calculated using the Kissinger and Ozawa equations. Considering that the calculated values are lower than those corresponding to the pure substrates, the complexes can be employed as combustion catalysts for composite propellants.

This paper reviews hydroxyl-terminal polybutadiene (HTPB) used as liner and binder for composite propellants, applied in rocket motors studied throughout the last decades, emphasizing the recent advances. The contribution aims to show the importance of HTPB in the propellant composition and on the liner coating of the rocket motor, which is in contact with the propellant grain. This paper also shows that many researchers have thoroughly studied several properties of HTPB, which are rele-vant to its role in liners and propellants. We have also reviewed analytical techniques such as Fourier Transform Infrared Spectroscopy (FTIR) as a characterization technique for HTPB and HTPB-based polyurethanes. Reflection and transfectants FTIR may be a future trend in studies about polymeric matrices for liners and propellants, and in the area of propellant formulations that use energetic binders, graphene and nanomaterials.
