Abstract (en)
[origin: WO2008041801A1] Disclosed herein is a catalyst composition for inhibiting the generation of NO<SUB>2</SUB>, comprising a basic metal oxide catalyst composition combined with ceria-cobalt oxide, active alumina, and zeolite, wherein the basic metal oxide catalyst composition is supported with a precious metal, such as platinum and/or palladium, and a non-precious metal, such as barium or strontium, and a module for inhibiting the generation of NO<SUB>2</SUB> using the catalyst composition. In the exhaust gas aftertreatment system, in which a DOC and a CSF are serially disposed, the module is disposed at the rear end of the CSF, so that the generation of NO<SUB>2</SUB> is prevented, with the result that the emission of visible exhaust gas is prevented, thereby contributing to environmental purification.
