Synthesis of Monodispersed Plate-Like CeO₂ Particles by Precipitation Process in Sodium Hydrogen Carbonate Solution

Abstract:

Monodispersed plate-like CeO2 particles were successfully synthesized by a mild solution process followed by calcination in air at 400oC. During the solution processing, monodispersed orthorhombic single-crystal of plate-like Ce2(CO3)3.8H2O was obtained by using Ce(NO3)3.6H2O as cerium source, and NaHCO3 aqueous solution as precipitation reagent and carbon source. The concentration of NaHCO3 solution affects the morphologies and particle size of the cerium carbonate compounds. High concentration of NaHCO3 led to a decrease in the particle size of Ce2(CO3)3.8H2O effectively. The CeO2 particles synthesized by the decomposition of carbonate precursors possessed similar morphologies and slightly smaller particle size. The plate-like ceria particles possessed good UV-shielding properties and low oxidation catalytic activities, indicating the potential application as cosmetics materials
