Product Description
Cerium Oxide (CeO₂) For Three-Way Catalysts | Automotive Emission Control Catalyst Material
Description
Cerium Oxide (CeO₂) is a critical rare earth material widely used as an oxygen storage and release component in automotive catalytic converters. It plays a central role in Three-Way Catalyst (TWC) systems by improving catalytic efficiency and enabling effective control of vehicle exhaust emissions.
Through its unique reversible redox behavior between Ce⁴⁺ and Ce³⁺ states, cerium oxide rapidly stores and releases oxygen during engine operation. This capability stabilizes air-fuel ratio fluctuations and enhances the simultaneous conversion of harmful exhaust gases including carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx).
Our catalyst-grade cerium oxide is engineered with optimized surface area, controlled particle size, and high thermal durability to support modern automotive emission standards and long catalyst service life.
