Abstract

The catalytic activity of Rh supported on Y-stabilized ZrO2 for NO–CO–C3H6–O2 reactions under stoichiometric conditions was improved by the addition of 5 mol % CeO2, whereas an excess amount of CeO2 of more than 10 mol % caused a decrease in the NO reduction activity. The improvement was ascribed to the formation of easily reducible Rh species through interaction with a Ce–Zr solid solution.
