The catalytic effect of NiO nanoparticles on the thermal decomposition of double-base propellant composed of nitrocellulose (NC) and triethylene glycol dinitrate (TEGDN) has been investigated by thermogravimetry-mass spectrometry (TG-MS) coupling technique. It was shown that adding 2% of NiO nanoparticles to TEGDN/NC propellant can accelerate the thermal decomposition process after around 188 degrees C TG-MS analysis indicated that NiO nanoparticles have resulted in the increase in intensity (peak area) of m/z=27, 28, and 29 MS signals, but the decrease in the intensity of m/z=18, 30, 44 and 46 (peak 2) MS signals during the thermal decompsition. The catalytic mechanism was also discussed in this paper.
采用热重-质谱联用技术研究了NiO纳米颗粒对由硝化纤维素（NC）和三乙二醇二硝酸酯（TEGDN）组成的双基推进剂热分解的催化作用。结果表明，在TEGDN/NC推进剂中添加2%的NiO纳米颗粒可在约188℃后加速热分解过程。热重-质谱分析表明，NiO纳米颗粒导致热分解过程中m/z = 27、28和29的质谱信号强度（峰面积）增加，但m/z = 18、30、44和46（峰2）的质谱信号强度降低。本文还讨论了催化机理。
