Abstract:

The Fe3O4 and Fe2O3 nanoparticles were successfully prepared by hydrothermal method. The Fe3O4 and Fe2O3 nanoparticles were characterized by X-ray powder diffraction (XRD) and the transmission electron microscopy (TEM).The obtained Fe3O4 and Fe2O3 were spheres and the diameter was about 10-20 nm. The catalysis activity of Fe3O4 and Fe2O3 on the thermal decomposition of ammonium perchlorate (AP) was appraised by thermalanalysis (TG-DSC). It was found that Fe2O3 and Fe3O4 nanoparticles had high catalysis activity on decomposition of AP. The results can be used as a comprehensive experimental course in the instrument analysis laboratroy. The students can learn the hydrothermal method and learn how to use XRD, thermal analysis and other means to characterize the compounds.

Key words: Fe2O3 nanoparticles, Fe3O4 nanoparticles, Ammonium perchlorate, Thermal analysis, Catalysis
