“…And the 30 (NO) and 46 (NO 2 À ) gas product may be appeared earlier at~160°C, and the NO until~430°C for recrystallized ADN. This phenomenon indicates that the decomposition begins with ammonium nitrate (the initial decomposition product of ADN [33]) dis- sociation into NO and NO 2 À . For the mixture, gases were generated at a lower temperature than those detected for ADN.…”

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.
