Abstract

Ultrasonic spray pyrolysis of acetate-based salt precursor with various concentrations is employed to produce nanocrystalline CeO2 particles in this study. The mean particle size of as-pyrolyzed CeO2 powders produced from precursor concentrations of 1.0, 0.1, and 0.01 wt.% are 350, 185, and 95 nm, respectively. We found that due to the low solubility of the precursor, the formation of a shell occurs during pyrolysis, leading the CeO2 particles to be bowl-like in shape with uneven surfaces. Precursor concentrations significantly determine the size of the product particles. The bimodal size distribution of the product particles suggests that both one-particle-per-drop and gas-to-particle conversion mechanisms are active in the process.
