| Abstract: | X ray diffraction analysis, X ray small angle scattering, SEM, TEM were used to compare the microstructures of the nanostructured CeO 2 synthesized by electrochemical and precipitation method. The CeO 2 synthesized by electrochemical method was consisted of dispersed particles with nano size. While the CeO 2 synthesized by precipitation was characterized with large flake shape, and the flake was consist of particles with nano size compactly. The microstructure of CeO 2 synthesized by electrochemical method is finer than that of by precipitation method. |
