“…Electron transfer processes from ClO 4 − to NH 4 + and from O 2 to superoxide ion (O 2 − ) are the controlling steps of LTD and HTD, respectively. After that, the generated O 2 − promotes the decomposition of NH 3 , eventually the AP is completely decomposed .…”

“…The endothermic peak appears at 245 °C is attribute to the phase transition of AP from orthorhombic to cubic form. Exothermic peaks appear at 296 and 404 °C, corresponding to the low thermal decomposition peak and high thermal decomposition peak of AP, indicating that the AP is completely decomposed .…”

Three kinds of ferrates (NiFe2O4, ZnFe2O4 and CoFe2O4) were prepared via the facile solvothermal method and characterized using SEM, TEM, XRD, XPS, FT‐IR and BET instruments. The NiFe2O4, CoFe2O4 and ZnFe2O4 particles possess hollow structure with average particle size of 70, 220 and 360 nm, respectively. The catalytic performance of the ferrates for AP thermal decomposition were studied using DSC and TG‐DTG methods, and the decomposition mechanism of AP were suggested. The catalytic effects of different ferrates for AP thermal decomposition were significantly different. The CoFe2O4 has the best catalytic activity, and the high thermal decomposition peak temperature (THDP) and apparent activation energy (Ea) of AP were decreased by 108.99 °C and 37.38 kJ mol−1 in the presence of CoFe2O4 sample. Adding ferrates has no obvious influence on the gas‐phase decomposition products of AP, but has a great influence on the energy barrier of high temperature decomposition of AP. The excellent catalytic activity of CoFe2O4 is mainly attributed to the synergistic interaction between Fe and Co, which is conducive to the thermal decomposition of AP.

“…Composite solid propellants are the most important power source for rockets and missile engines and are required to have favorable combustion performances. [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.…”

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.

“…Typically, graphene is often used in double-layer capacitors according to the adsorption/desorption mechanism. Unfortunately, several factors have limited its performance gains, such as the fact that the surface of a material is not easy soaked by the electrolyte; and the stronger van der Waals force between sheets is easily causing agglomeration of graphene sheets [41,42]. Therefore, combining graphene with metal oxide particles to form spacers between the layers not only prevents the layers from stacking but also further improves their performance due to synergistic effects [36,[43][44][45].…”

Two-dimensional (2D) materials have attracted extensive attention in various fields due to their good flexibility, high specific surface area and fast ion transfer rate. Herein, the α-Fe 2 O 3 nanoparticles/ graphene composites have been prepared through a hydrothermal method, which is followed by hydrogen annealing to produce oxygen vacancies. Electrochemical properties and photoelectrochemical properties are investigated. The results present a high specific capacitance and the electrochemical properties are improved ascribing to the synergistic effect of graphene's large specific surface area and excellent electrical conductivity, as well as the pseudocapacitance of transition metal oxides. Moreover, it also promotes the photoelectric response performances in visible light. This work provides a basis for the development and application of transition metal oxide in electrochemical and photoelectric fields.
