Continuous Fabrication of Monodisperse Ceria-Zirconia-Yttria Composite Oxide Nanoparticles Using a Novel High-Shear Agitation Reactor.

Monodisperse ceria-zirconia nanoparticles have attracted much attention as potential high-performance catalysts. Acidic aqueous solutions are generally used for peptizing aggregated precipitates during the fabrication of disperse nanoparticles. However, the peptization process requires multiple hours of aging, which significantly decreases the production efficiency.
