Abstract
Antimony oxide (Sb 2O 3) has wide applications as conductive materials, effective catalyst, functional filler and optical materials. Nanocrystalline Sb 2O 3 has been successfully synthesized by hydrolysis-precipitation method. The samples were characterized by means of transmission electron microscopy (TEM), high-resolution TEM (HRTEM) images, X-ray diffraction (XRD) and differential thermal analysis (DTA). The average crystal size of the Sb 2O 3 nanoparticles increases with increasing the reaction temperature. TEM image of the as-synthesized nanocrystalline Sb 2O 3 shows rod-like structure. HRTEM images indicate a preferred directional growth of the Sb 2O 3 nanoparticles. The electrochemical behaviors of Sb 2O 3 electrodes have been primarily investigated by cyclic voltammetry (CV) in lithium hexafluorophosphate (LiPF 6) solution. Sb 2O 3 nanocrystallite phase has prominent effect on the electrochemical properties. The results indicate that nanocrystalline Sb 2O 3 synthesized by hydrolysis-precipitation method shows potential application in the field of the electrode materials.
