中文摘要	The Cu(OH)(2)center dot 2Cr(OH)(3) nanoparticle preparation procedure and its accelerating effect and accelerating mechanism on thermal decomposition of ammonium perchlorate (AP) were investigated using transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), selected area electron diffraction (SAED), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis and differential scanning calorimetry (TG-DSC), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis and mass spectroscopy (TG-MS). In the preparation procedure, TEM, SAED, and EDS showed that the Cu(OH)(2)center dot 2Cr(OH)(3) particles were amorphous with nanometer size under the controllable preparation conditions. When the amorphous Cu(OH)(2)center dot 2Cr(OH)(3) nanoparticles were used as additives for the thermal decomposition of AP, the TG-DSC results showed that the addition of Cu(OH)(2)center dot 2Cr(OH)(3) nanoparticles to AP remarkably decreased the onset temperature of AP decomposition from approximately 450 degrees C to 259 degrees C. The XRD and FT-IR results confirmed that the Cu(OH)(2)center dot 2Cr(OH)(3) nanoparticles were transformed from amorphous form to Cr2O3 and CuCr2O4 phases after being used as additives for the AP thermal decomposition. The XPS results indicated that Cu2+ of the Cu(OH)(2)center dot 2Cr(OH)(3) surface gained the electron from the perchlorate ion of AP, and the Cu ions were enriched on the Cu(OH)(2)center dot 2Cr(OH)(3) surface in the AP decomposition. The electron transfer process plays a major role in the decrease of the onset temperature of AP decomposition, while the nano-effect is beneficial to easier enrichment of Cu ions on the surface of Cu(OH)(2)center dot 2Cr(OH)(3) nanoparticles.
