Abstract

Development of energetic catalysts with high energy density and strong catalytic activity has become the focus and frontier of research, which is expected to improve the combustion performance and ballistic properties of solid propellants. In this work, three energetic catalysts, M(HO)(AFCA)·HO (AFCA = 3-aminofurazan-4-carboxylic acid, M = Cu, Co, Fe), are designed and synthesized based on the coordination reaction of transition metal ions and the energetic ligand. The target products are characterized by single crystal X-ray diffraction, Fourier transform infrared spectroscopy, differential thermal analysis, optical microscopy, and scanning electron microscopy. The results reveal that Cu(HO)(AFCA)·HO crystallizes in the monoclinic space group, = 1.918 g cm. Co(HO)(AFCA)·HO, and Fe(HO)(AFCA)·HO belong to orthorhombic space groups, their density is 1.886 g cm and 1.856 g cm, respectively. In addition, the designed catalysts show higher catalytic activity than some reported catalysts such as Co(en)(HBTI)]·en (HBTI = 4,5-bis(1-tetrazol-5-yl)-1-imida-zole), Co-AzT (HAzT = 5,5'-azotetrazole-1,1'-diol), and [Pb(BTF)(HO)] (BTF = 4,4'-oxybis [3,3'-(1-hydroxy-tetrazolyl)]furazan) for the thermal decomposition of ammonium perchlorate (AP). The high-temperature decomposition peak temperatures of AP/Cu(HO)(AFCA)·HO, AP/Co(HO)(AFCA)·HO, and AP/Fe(HO) (AFCA)·HO are decreased by 120.3 °C, 151.8 °C and 89.5 °C compared to the case of pure AP, while the heat release of them are increased by 768.8 J g, 780.5 J g, 750.9 J g, respectively. Moreover, the burning rates of solid propellants composed of AP/Cu(AFCA)(HO)·HO, AP/Co(AFCA)(HO)·HO and AP/Fe(AFCA)(HO)·HO are increased by 2.16 mm s, 2.53 mm s, and 1.57 mm s compared with the case of pure AP. This research shows considerable application prospects in improving the combustion and energy performance of solid propellants, it is also a reference for the design and preparation of other novel energetic catalysts.

摘要

开发具有高能量密度和强催化活性的含能催化剂已成为研究的重点和前沿领域,有望改善固体推进剂的燃烧性能和弹道性能。在本工作中,基于过渡金属离子与含能配体的配位反应,设计并合成了三种含能催化剂M(HO)(AFCA)·HO(AFCA = 3-氨基呋咱-4-羧酸,M = Cu、Co、Fe)。通过单晶X射线衍射、傅里叶变换红外光谱、差热分析、光学显微镜和扫描电子显微镜对目标产物进行了表征。结果表明,Cu(HO)(AFCA)·HO以单斜空间群结晶,密度为1.918 g/cm³。Co(HO)(AFCA)·HO和Fe(HO)(AFCA)·HO属于正交空间群,其密度分别为1.886 g/cm³和1.856 g/cm³。此外,所设计的催化剂对高氯酸铵(AP)热分解的催化活性高于一些已报道的催化剂,如Co(en)(HBTI)]·en(HBTI = 4,5-双(1-四唑-5-基)-1-咪唑)、Co-AzT(HAzT = 5,5'-偶氮四唑-1,1'-二醇)和[Pb(BTF)(HO)](BTF = 4,4'-氧双[3,3'-(1-羟基四唑基)]呋咱)。与纯AP相比,AP/Cu(HO)(AFCA)·HO、AP/Co(HO)(AFCA)·HO和AP/Fe(HO)(AFCA)·HO的高温分解峰温度分别降低了120.3℃、151.8℃和89.5℃,而它们的热释放分别增加了768.8 J/g、780.5 J/g、750.9 J/g。此外,由AP/Cu(AFCA)(HO)·HO、AP/Co(AFCA)(HO)·HO和AP/Fe(AFCA)(HO)·HO组成的固体推进剂的燃速与纯AP相比分别提高了2.16 mm/s、2.53 mm/s和1.57 mm/s。本研究在改善固体推进剂的燃烧和能量性能方面显示出可观的应用前景,也为其他新型含能催化剂设计与制备提供了参考。
