Hydrothermal Synthesis of V-Cr-Al-O Nanospheres and Their Effect on Decomposition of Ammonium Perchlorate

Abstract

V-Cr-Al-O nanospheres were successfully synthesized using V₂O₅, Al(OH)₃, CrO₃, and H₂C₂O₄₂O 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 °C (decreased by 35 °C), which proves better catalyst for the thermal decomposition of AP.
