“…Well‐known ferrocene‐based combustion modifiers include n‐butyl ferrocene (NBF), tert‐butyl ferrocene (TBF) and binuclear 2,2‐bis (ethyl ferrocene) propane (Catocene) [10] . The disadvantages of the first two listed compounds include easy migration into the insulating layer during curing and storage and evaporation and sublimation losses during processing [11,12] . The binuclear ferrocene derivative Catocene was subsequently developed to retard the migration trend, but after long‐term storage, a slower migration of Catocene to the propellant surface was still observed; [13] to overcome these shortcomings, researchers designed and synthesized novel ferrocene derivatives based on the combustion rate catalyst, successfully improved its storage stability [14] .…”

In order to improve the catalytic performance, oxidation resistance and thermal stability of neutral alkyl ferrocene-based combustion rate catalysts, mononuclear ferrocene energetic compounds were designed and prepared, but four binuclear ferrocene energetic compounds were unexpectedly discovered during the synthesis compounds. The new compounds were characterized by single-crystal X-ray diffraction, 1 H and 13 C nuclear magnetic resonance spectroscopy, and high-resolution mass spectrometry. The crystal structures of compounds a, b, c and d confirmed that we have successfully prepared binuclear ferrocene nitrogen-containing heterocyclic compounds. The thermogravimetric results revealed that most of the compounds exhibit high thermal stability. The electrochemical properties of the four compounds were examined by cyclic voltammetry (CV) and differential pulse voltammetry; the CV experimental results indicated that these compounds showed good electrochemical performance, which contributed to their burning rate catalytic activity in composite solid propellants. Differential scanning calorimetry was used to study the catalytic performance of the binuclear ferrocene energetic compounds for ammonium perchlorate (AP). The results show that these compounds have a good combustion catalytic effect on AP due to the increase in the number of ferrocene groups.

“…45 Density is an important parameter for evaluating the physicochemical properties of energetic materials. The densities of the five complexes range from 1.799 to 1.964 g/cm 3 and Complex 2 has the highest crystallographic density of 1.964 g/cm 3 . These five complexes show extremely structural similarities.…”

“…Composite solid propellant (CSP), a heterogeneous energetic composite material, has an important impact on the development of the defense and space industry as a power source for missiles, aircraft, and spacecraft. − The composition of CSP includes a solid oxidizer, a polymer binder, a metal fuel, and other functional components, with the solid oxidizer occupying most of the composition (40–90 wt %). , Ammonium perchlorate (AP) is the most widely used solid oxidant and is characterized by high oxygen content, high gas release, low sensitivity to external impact, compatibility with other components, and low cost. − However, the major challenge faced by the extensive application of AP is overcoming the too-high of a decomposition temperature, accompanied by unfocused heat release, low combustion rates, and wasted raw materials. − …”

To improve the combustion performance of ammonium perchlorate (AP), more high-performance combustion catalysts need to be developed. In this paper, five new types of energetic coordination complexes were prepared by combining 3aminofurazan-4-carboxylic acid (AFCA) with transition metals (Co, Ni, Fe, Cu, and Mn). The structures were determined by singlecrystal X-ray diffraction. Differential scanning calorimetry and thermogravimetric analysis were performed to characterize the thermal stability of the complexes. The five complexes exhibit superior energy properties to traditional explosive TNT. The thermal stability of the complexes was improved to a certain extent after binding to the metal. Catalytic experiments were performed by adding 10 wt % complexes to AP with differential thermal analysis instruments. Results indicate that the best catalyst is manganese as the metal center, which decreases the high-temperature decomposition (HTD) peak of AP by 133.3 °C and the activation energy (E) of AP by 102.2 kJ/mol and increases the mixture heat release by more than four times. Thermogravimetric analysis-Fourier transform infrared spectroscopy was applied to monitor the process of catalyzing AP, which indicates that the HTD of AP was advanced substantially. The combustion experimental results show that AP with complex 4 and complex 5 can burn vigorously. Overall, the furazan-based complex catalysts we synthesized have a good catalytic potential for solid propellant.
