摘要
由于其多样的结构构型和优异的热稳定性,高能配合物被广泛用作高氯酸铵(AP)热分解的催化剂。然而,提高这些高能配合物的催化活性仍然是一个重大的挑战。本研究以3-氨基吡唑-4-羧酸(H2apza)为能配体,通过水热法成功合成了3个富氮杂环配合物M(Hapza)2(H2O)4 (M = Co, Zn, and Cd)。单晶x射线衍射分析表明,这三种配合物均为单核同构,通过广泛的氢键网络形成热稳定的三维超分子结构。与传统含能材料相比,这些配合物具有更高的爆轰速度(8.9 ~ 9.4 km s−1)和爆轰压力(36.1 ~ 42.4 GPa),使AP的高分解峰提前了26.9 ~ 51.4℃,活化能降低了41.19 ~ 52.99 kJ mol−1,显示了它们对AP的显著催化作用。对其可能的催化机理的进一步研究表明,金属配合物分解产生的金属氧化物可能促进AP高温分解阶段的电荷转移和NH3的解吸。该研究突出了实验和理论分析的重要性,为配合物在含能材料领域的发展提供了新的视角。
Thermal decomposition catalytic properties of ammonium perchlorate with three new energetic complexes on the basis of metal centre regulation
Due to the diverse structural configurations and exceptional thermal stability, energetic complexes have been extensively utilized as catalysts for the thermal decomposition of ammonium perchlorate (AP). Nevertheless, enhancing the catalytic activity of these energetic complexes remains a significant challenge. In this study, three nitrogen-rich heterocyclic complexes, M(Hapza)2(H2O)4 (M = Co, Zn, and Cd), were successfully synthesized by the hydrothermal method using 3-aminopyrazole-4-carboxylic acid (H2apza) as an energetic ligand. Single-crystal X-ray diffraction analysis revealed that the three complexes are single-nucleated and isomorphic, forming thermally stable three-dimensional supramolecular structures through extensive hydrogen bonding networks. The incorporation of these complexes significantly advanced the high decomposition peak of AP by 26.9–51.4 °C and reduced the activation energy (Ea) by 41.19–52.99 kJ mol−1, demonstrating their remarkable catalytic effect on AP. The detonation properties of the complexes were evaluated using the Kamlet-Jacobs equation, revealing that these complexes possess higher detonation velocities (8.9–9.4 km s−1) and detonation pressures (36.1–42.4 GPa) compared to traditional energetic materials. Further investigation into the possible catalytic mechanism suggested that metal oxides, generated from the decomposition of metal complexes, may facilitate charge transfer and enhance the desorption of NH3 during the high-temperature decomposition stage of AP. This study highlights the importance of experimental and theoretical analysis, providing a fresh perspective for the development of complexes in the field of energetic materials.
