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 (CuCrO₄), copper chromite (Cu₂Cr₂O₅), copper 2,4‐dihydroxybenzoate (β‐Cu) and metal‐organic framework copper (MOF−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 MOF−Cu slightly promote the thermal decomposition of ADN, the ADN/MOF−Cu system release more heat during exothermic reaction owing to the high energy of MOF−Cu.

不同铜基催化剂上双乙酰胺铵的热行为研究

系统研究了不同铜催化剂对二硝酰胺（ADN）的热行为的影响。通过研磨以100/5的比例制备ADN /铜催化剂混合物，并使用热重分析，傅立叶变换红外光谱（TGA-FTIR）和质谱对所有样品进行TG-DSC研究，从而获得了析出的气体产物有关热解和氧化降解的详细信息。四种铜系列催化剂，包括铬酸铜（CuCrO ₄），亚铬酸铜（Cu ₂ Cr ₂ O ₅），2,4-二羟基苯甲酸铜（β-Cu）和金属有机骨架铜（MOF-Cu）用于研究样品的外观形态和热行为。TG-DSC对ADN /催化剂分解的分析表明，亚铬酸铜和β- Cu的催化活性高于铬酸铜，这是因为它们对ADN的热分解作用更大。此外，尽管MOF-Cu稍微促进了ADN的热分解，但由于MOF-Cu的高能量，ADN / MOF-Cu系统在放热反应过程中释放出更多的热量。
