Industrial Grade Cerium Zirconium Solid Brown Rare Earth Catalyst Cerium-zirconium mixed oxide (CeO₂-ZrO₂) is a high-performance oxygen storage material engineered for automotive three-way catalysts and other emission control systems. By incorporating zirconia into the ceria lattice to form a homogeneous solid solution, the material achieves significantly enhanced redox properties and thermal stability compared to pure ceria. 【Application】 (1) Catalysis of automobile and
