Abstract

The three-way activity under complex feed-streams of a series of Pt/Ce0.68Zr0.32O2 catalysts, either fresh or submitted to different ageing treatments, both before and after reduction, has been studied and related to the species present on the catalysts in view of their characteristics and TPR behaviour.
