Synthesis of nano-particles of CeO2 by auto-combustion method

Abstract

Nano-particles of CeO₂ with the smallest average particle size (from 10 to 20 nm) and uniform morphology, well- dispersion, especially with single crystal of CeO₂ were obtained from a mixed  solution of Ce(NO₃)₃, citric acid, polyvinyl ancohol by auto-combustion method. The synthesized CeO₂ powders were characterized as the crystalline phase identification by X-ray diffraction (XRD), the morphology and particle size by trasmission electron microscopy (TEM), the single crystal of CeO₂ was determinated by selected area electron diffraction (SAED).
