摘要

本研究考察了活性炭/纳米氧化钴(AC-Co3O4)作为一种新型催化添加剂提高硝酸铵/镁/硝化纤维素(AN/Mg/NC)复合材料效率的潜力。这些发现表明,与最初的AN/Mg/NC相比,AN/Mg/NC/AC-Co3O4的热特性有了显著改善。拉曼光谱证实了AC的多层性质,傅里叶变换红外光谱(FTIR)分析证实了合成添加剂中存在氧化钴。差示扫描量热法(DSC)揭示了AC-Co3O4对AN/Mg/NC复合材料的催化作用,使分解峰温度(Tmax)从AN/Mg/NC的277.4℃降低到AN/Mg/NC的215.2℃。热重分析(TG)确定了AN/Mg/NC(70%)、AN/Mg/NC/AC(75%)和AN/Mg/NC/AC- co3o4(80%)的总质量损失(%)。这一分析突出了AC-Co3O4在促进分解过程中能量释放方面的重要作用。此外,利用差热重(DTG)技术证明了多组分体系的两步分解途径。最后,在3.5 MPa压力下进行了燃烧试验,验证了AC-Co3O4添加剂的催化效率,使AN/Mg/NC/AC-Co3O4复合材料的燃烧速率(rb)从最初的AN/Mg/NC复合材料的10.29 mm/s提高到19.84 mm/s。AN/Mg/NC/AC-Co3O4复合材料具有较低分解温度的优势,可应用于火箭推进系统,在火箭推进系统中,精确控制燃烧和点火过程至关重要。

Thermal Characteristics Enhancement of AN/Mg/NC Composite Using Activated Carbon/Cobalt Oxide as Highly Effective Catalytic Additive
Our study examined the potential of using activated carbon/nanosized cobalt oxide (AC-Co3O4) as a new catalytic additive to improve the efficiency of the parent ammonium nitrate/magnesium/nitrocellulose (AN/Mg/NC) composite. These findings demonstrate a significant improvement in the thermal characteristics of AN/Mg/NC/AC-Co3O4 compared to the initial AN/Mg/NC. Raman spectra confirmed the multilayered nature of AC. Fourier-transform infrared spectroscopy (FTIR) analysis confirmed the presence of cobalt oxide in the synthesized additive. Differential scanning calorimetry (DSC) revealed the catalytic effect of AC-Co3O4 on the AN/Mg/NC composite, resulting in the reduction in the decomposition peak temperature (Tmax) from 277.4 °C (for AN/Mg/NC) to 215.2 °C (for AN/Mg/NC/AC-Co3O4). Thermal gravimetric analysis (TG) determined the overall mass losses (%) for AN/Mg/NC (70%), AN/Mg/NC/AC (75%), and AN/Mg/NC/AC-Co3O4 (80%). This analysis highlights the significant role of AC-Co3O4 in enhancing the energy release during decomposition. Moreover, the use of the differential thermogravimetric (DTG) technique demonstrated the two-step decomposition pathways attributed to the multi-component system. Finally, the combustion tests under the pressure of 3.5 MPa validated the catalytic efficiency of the AC-Co3O4 additive, which enhanced the burning rate (rb) of the AN/Mg/NC/AC-Co3O4 composite from 10.29 to 19.84 mm/s compared to the initial AN/Mg/NC composite. The advantageous nature of the AN/Mg/NC/AC-Co3O4 composite with a lowered decomposition temperature can be applied in rocket propulsion systems, where the precise control of combustion and ignition processes is crucial.
