摘要: The rare-earth oxide nanoparticles along carbon nanotubes (CNTs) (M2O3/CNTs, M = Y, Nd, Sm) were prepared by in situ solvothermal method. Products characterized infrared spectroscopy, X-ray diffraction, transmission electron microscopy, energy-dispersive spectrometry, scanning and Brunauer-Emmett-Teller M2O3/CNTs presented good morphology large surface area. Furthermore, catalysis of during the thermal decomposition ammonium perchlorate (AP) was evaluated differential analysis (DTA). Compared with Nd2O3/CNTs Sm2O3/CNTs, Y2O3/CNTs nanocomposites showed best catalytic effect on AP. With addition 2 wt.% nanocomposite, high temperature AP decreased 125.5°C, total DTA heat release increased 2.027 kJ·g−1.
