In this paper, the catalytic conversions processes of CO, HC and NOx over the automotive three-way catalyst (TWC) for gasoline engine were investigated in a synthetic exhaust mixture, and the results show that NO in exhaust is reduced by both CO in exhaust and CO generated by HC oxidation.
The effect of alumina coating materials with different thermal stabilities on the catalytic performance of THC aged was studied. We have found that the TWC prepared with alumina (A-B) with high thermal stability exhib...
