Y2O3 nanoparticle /carbon nanotube composite has been prepared by chemical liquid deposition. Y2O3 nanoparticle /carbon nanotube composite obtained has been characterized by SEM and XPS. The results show that Y2O3 nanoparticles are supported well on the surface of carbon nanotube. The thermal decomposition of ammonium perchlorate (AP) in the presence of Y2O3 nanoparticle /carbon nanotube composite has been investigated by DTA. The results indicate that Y2O3 nanoparticle /carbon nanotube composite has a strong catalytic effect on the thermal decomposition of AP. In comparison with that of pure Y2O3 nanoparticles, the catalytic performance of Y2O3 nanoparticle /carbon nanotube composite is superior to that of pure Y2O3 nanoparticles. When the quantity of Y2O3 nanoparticle /carbon nanotube composite is 4%(w), the catalytic effect is the best, and the peak temperature of high temperature decomposition of AP by 131.14 C[deg].
