Nanometer Sized CeO2 Particles Prepared by Coupling Homogeneous Precipitation and Carbon Absorption and Their Characterization
Abstract:
CeO2 nano-powders were synthesized by coupling homogeneous precipitation and carbon adsorption method. The effect of the amount of added carbon on the nano-powder size was investigated. The optimal carbon to Ce(NO3)3 mole ratio is 3. The phase,particle shape,particle size and specific surface area of CeO2 particles were characterized by XRD,TEM and BET. CeO2 powder calcined at 700℃ is cubic fluorite and has a surface area of 53.6 m2/g. The average particle size is about 18 nm. The structures of the products calcined at 800~900℃ remain stable and no agglomeration could be observed.
