Doped Zirconia with Acidity and High Thermal Stability, for Durable Diesel Catalysts 2007-01-0238

Acidic doped zirconia catalyst supports with high thermal stability and high SOx resistance have been tested in Diesel exhaust. This paper focuses on the optimization of these materials to get the best trade-off between acidity and thermal stability. These materials were tested as a Platinum support for Diesel Oxidation Catalysts (DOC). Preliminary data are also discussed concerning their ammonia adsorption properties for the Selective Catalytic Reduction of NOx by ammonia (SCR).
