“…The isoconversional approach yielded an activation energy value of approximately 147 kJ/mol for pristine AN. This result is consistent with previously reported values in the literature [12, 66, 67], which reinforces the reliability of our findings. However, in the case of the N‐rGO@Fe 2 O 3 /AN sample, the current state of knowledge is limited as there is a notable absence of available data.…”

In this investigation, we successfully synthesized a hybrid material, N‐rGO@Fe2O3, via a one‐step hydrothermal process, comprising nitrogen‐doped reduced graphene oxide and α‐Fe2O3. Thorough characterization using diverse analytical methods validated its structure. Employing this hybrid composite as a catalyst, we studied its efficacy in the catalytic thermal decomposition of ammonium nitrate (AN). The N‐rGO@Fe2O3/AN composite was prepared using a recurrent spray coating method with 3 % mass of the hybrid material. Thermo‐gravimetric (TG) and differential scanning calorimetric (DSC) analyses were employed to investigate the catalytic effect. Computational assessment of Arrhenius parameters was conducted through isoconversional kinetic approaches. Results from the kinetic analysis allowed the determination of the critical ignition temperature. Furthermore, calorific values for pure AN and N‐rGO@Fe2O3/AN were measured using an oxygen calorimetric bombe, revealing a 41 % reduction in activation energy barrier and a lowering of the critical ignition temperature from 292 °C to 283 °C upon incorporation of the hybrid material. Notably, the surface modification of AN with N‐rGO@Fe2O3 resulted in an increase of 1440 J/g in the observed calorific values. These findings highlight the potential of N‐rGO@Fe2O3 as an effective catalyst, offering promising implications for applications in enhancing ammonium nitrate thermal decomposition.

“…Ammonium dinitramide [NH 4 N(NO 2 ) 2 , ADN] is considered as a novel energetic material for the environmental friendly oxidizer that can be used in solid-rocket propellants and liquid monopropellant in the coming future [1][2][3]. ADN possesses a high oxygen balance and does not contain halogen atoms, and it can provide high energy levels for solid propellants.…”

A systematic investigation of the effects of different copper catalysts on the thermal behavior for ammonium dinitramide (ADN) was performed. ADN/copper catalyst mixtures were prepared in the ratio of 100/5 by grinding, and all samples were subjected to TG-DSC studies using thermo-gravimetric analysis coupled to Fourier Transformed Infrared Spectrometry (TGA-FTIR) and Mass Spectrometry, which obtained the detailed information of evolved gas products on pyrolysis and oxidative degradations. Four copper-series catalysts including copper chromate (CuCrO 4), copper chromite (Cu 2 Cr 2 O 5), copper 2,4-di-hydroxybenzoate (β-Cu) and metal-organic framework copper (MOFÀ Cu) were employed to research the appearance morphology and thermal behavior of the samples. TG-DSC analysis of the decomposition for ADN/catalyst revealed that copper chromite and β-Cu exhibit higher catalytic activity than copper chromate due to their greater acceleration of thermal decomposition for ADN. Besides, though MOFÀ Cu slightly promote the thermal decomposition of ADN, the ADN/MOFÀ Cu system release more heat during exothermic reaction owing to the high energy of MOFÀ Cu.

“…In the coming years to reduce environmental problems, various research studies will be carried out to produce smokeless combustible energy fuels without chlorine. Many studies support the use of HMX and RDX [2] as an oxidant instead of AP, addition of magnesium [3] into the rocket fuel of AP, the use of ADN [4] and energy fuels based on AN [5][6][7].…”

Ammonium nitrate (AN)-based composite gas generator have attracted a considerable amount of attention because of the clean burning nature of AN as an oxidizer. However, ammonium nitrate-based gas generator has several major problems, namely, poor ignitability, a low burning rate, low energy, and high hygroscopicity. The addition of different transitional metal oxides and MgAl mechanical alloyed proved to be effective in improving the burning characteristics of AN-based gas generator. In this research work, combustion study of different transition metal oxide based on AN/MgAl composites gas generators was studied. Gas generators were combusted at the pressure of 1 MPa, 3 MPa and 5 MPa in the combustion chamber and the burning rates were determined. It was stated that the addition of metal oxides into the composition of the gas generators improves ignition at low pressure and increases the burning rate. The use of the mechanical MgAl alloys as a fuel allowed the ignition of the gas generator at a lower temperature. The method of thermogravimetric/differential thermal analyzer (TG/DTA) was used to investigate the effect of metal oxides addition on the AN/MgAl-based gas generators thermal decomposition characteristics.
