摘 要：V-Cr-Al-O nanospheres were successfully synthesized using V2O5, Al（OH）3, CrO3, and H2C2O4·H2O as the starting materials by a facile one-pot hydrothermal approach. Several techniques containing X-ray powder diffraction, hydrogen temperature programmed reduction, scanning electron microscopy were used to characterize the composition, morphology and redox property of V-Cr-Al-O nanospheres. The catalytic behavior of prepared nanospheres on the thermal decomposition of AP was investigated by the thermogravimetric analysis and differential thermal analysis（TG/DTA）. The experimental results show that the thermal decomposition temperature of AP in the presence of V-Cr-Al-O nanospheres is to 395 ℃（decreased by 35 ℃）, which proves better catalyst for the thermal decomposition of AP.
