Mixed oxides for automotive TWC applications
The field of Autocatalysis is very much legislation driven and this varies significantly dependent upon geographical location. This results in the need for advanced materials to meet the performance requirements, particularly after accelerated aging cycles.
Catalytic converters for gasoline vehicles simultaneously convert NOx, CO and Hydrocarbons in the exhaust (hence Three Way Catalysis, TWC). Luxfer MEL Technologies’ Ceria Zirconia Mixed Oxides are a key component in this process as they act as an oxygen buffer to ensure optimal conditions for pollutant control.
We have developed customized formulations for gasoline TWC, Gasoline Particulate Filters (GPF), Diesel Oxidation Catalysts (DOC), Diesel Particulate Filters (DPF), passive NOx Absorbers (PNA), and selective catalytic reduction (SCR).
