Cerium Oxide Catalyst Material

Product introduction

Cerium Oxide, also called Ceria, is widely applied in glass, ceramic and catalyst manufacturing. In catalytic systems for a variety of applications, Cerium dioxide (CeO2, ceria) has become an ubiquitous constituent. It is used as an oxygen storage component in car converters, play an irreplaceable role in three-way catalysts (TWCs) today.

Beside TWC, application areas of cerium-containing catalysts also include selective oxidation, combustion, NOx remediation, and the production of sustainable chemicals and materials via bio-based feedstocks, among others.

As we know, the stability of the catalyst is the crucial factor for industrial application, and the speedy deactivation of the catalysts is also one of the prominent reasons. The cerium-containing catalysts are found with excellent selectivity, activity, and stability, these benefits arise because of cerium’s unique combination of chemical and thermal stability, its redox active properties, its ability to stabilize defect structures in multicomponent oxides, and its propensity to stabilize catalytically optimal oxidation states of other multivalent elements.

Honmat technical team are dedicated in research of Cerium Oxide Catalyst Material, developed new Cerium Oxide Catalyst formulas, which help customers improve the catalyst conversion performance of stablity and reliability significantly, meet Euro5, Euro6, Tier and EPA emission standards consistently.
