| Abstract: | Nanometer copper resorcylic catalyst was synthesized by reactive precipitation method. The samples obtained were characterized by X-ray diffraction (XRD), transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR) and thermo gravimetric analyses (TG). The results indicated that a spherical resorcylic catalyst was obtained after treatment in ethanol solvent, and flake shape crystal after treatment in water solvent. Peak temperature for thermal decomposition of NC/NG decreased by 3 ℃, and decomposition enthalpy increased by 735 J·g－1.The catalyst hadremarkable catalytic effects in double base propellant NC/NG thermal decomposition. |
