Combination of 3-Aminofurazan-4-carboxylic Acid and Transition Metals to Prepare Functional Energetic Catalysts for Catalyzing the Decomposition of Ammonium Perchlorate

Tao Huang et al.

Summary: Five new types of energetic coordination complexes were synthesized and used as catalysts for ammonium perchlorate (AP). The complexes, when bound to transition metals, exhibited improved thermal stability. The best catalyst was found to be the one with manganese as the metal center, which significantly reduced the high-temperature decomposition of AP and increased the heat release. The catalytic process was monitored using thermogravimetric analysis-Fourier transform infrared spectroscopy, which showed a substantial advancement in the decomposition of AP. AP with complex 4 and complex 5 exhibited vigorous combustion.

Exoergic pathways triggered by O/H radicals in different metallic carbohydrazide perchlorates (M2+ = Mn2+, Fe2+, Co2+, Ni2+, Zn2+ and Cd2+)

Xiaohui He et al.

Summary: This study used DFT and Car-Parrinello molecular dynamics to investigate the electronic structures and decomposition pathways of metallic carbohydrazide perchlorates (MCPs). The research found that crystalline MCPs with larger electronic band gaps exhibit lower impact sensitivity, while the friction sensitivity is determined by the strength of intermolecular interactions. Additionally, the decomposition process of MCPs consists of two stages: nonspontaneous departure of the CHZ groups and spontaneous exoergic decomposition pathways triggered by the transfer of O/H radicals.
