“…The transition metal oxides investigation of combustion catalysts is crucial for the catalysis of TKX‐50 thermal decomposition; the introduction of metal elements in combustion catalyst can improve the catalytic performance of the catalyst. The preliminary study, Fe exhibited excellent catalytic activity for thermal decomposition of energetic ionic salts, including TKX‐50 11‐13 . Up to now, metal oxides have been reported as combustion catalysts 13‐21 .…”

Synthesis, characterization, and catalytic behaviour of nano-bimetallic nickel oxide on the thermal decomposition of dihydroxylammonium-5,5 0 -bistetrazole-1,1 0 -diolate)Bimetal combustion catalyst has become an emerging field in recent years, which is still in its infancy. When the combustion catalyst is used in double-base propellants, it can produce effects that conventional catalysts cannot achieve. In this study, nano-bimetallic nickel oxides (nanospheres of NiFe 2 O 4 and the sub-nanometre flower NiCo 2 O 4 ) were prepared by hydrothermal method and characterized using X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and N2 adsorption-desorption test (BET). Moreover, its thermal catalytic action on dihydroxylammonium 5,5'-bistetrazole-1,1'-diolate (TKX-50) was studied. The thermal analysis of composite TKX-50/NiFe 2 O 4 and TKX-50/NiCo 2 O 4 was carried out by thermogravimetric differential scanning calorimetry (TG-DSC). The results show that when the addition amount of NiFe2O4 is 10%, the heating rate is 5.0 K min −1 , the NiFe 2 O 4 has the best catalytic activity for TKX-50 thermal decomposition, and the high thermal decomposition peak temperature (Tpeak1) is decreased by 29 °C. More interestingly, the apparent activation energies of the two composites were calculated by Kissinger, Ozawa, and Starink methods. The advanced thermal analysis kinetics software (AKTS) was used to perform kinetic calculations on the DSC experimental curves of the abovementioned composite energetic materials, and reaction rate curves obtained by the simulation are in good agreement with the experimental curves of the thermal decomposition reaction process, further proving that the accuracy of the experiment is high. Therefore, the addition of NiFe 2 O 4 shows high catalytic efficiency on the thermal decomposition of TKX-50 components, and this would be beneficial to promote the burning rate of propellants containing TKX-50 components.
