Rare Earth Oxide Oxygen Storage Materials

Rare earth oxide oxygen storage materials, such as ceria-zirconia solid solutions, play a critical role in three-way catalysts (TWC) for automotive emission control. In automotive emission control catalysts, ceria-zirconia mixed oxides primarily function as an oxygen storage/release (OSC) component and a catalyst stabilizer.

Ceria-Zirconia Mixed Oxides

Solvay (Belgium) is an absolute leader in the global field of rare earth catalytic materials. In the area of automotive emission control (Three-Way Catalyst, TWC), the rare earth oxides manufactured by Solvay—primarily ceria-based ceria-zirconia mixed oxides—serve as the 'core chip' that determines catalyst performance. Primarily applied in automotive and motorcycle emission control, as well as industrial waste gas VOC abatement.
