Nox reduction catalyst and nox reduction system |
摘要 |
A NOx reduction catalyst for exhaust gas discharged from an automotive internal combustion engine operable in a lean region and in a range including a stoichiometric region and a rich region. The NOx reduction catalyst comprises a catalytic noble metal. Additionally, an oxygen adsorbable and releasable material is provided carrying at least a part of the catalytic noble metal. In this catalyst, the catalytic noble metal carried on the oxygen adsorbable and releasable material adsorbs SOx in the exhaust gas, in a form of at least one of sulfate and sulfite. <IMAGE> |
