title: Interaction of Perchloroethylene with Cerium Oxide in Three-Way Catalysts.
abstract: The role of cerium oxide on direct oxidation of perchloroethylene (PCE) by a three-way catalyst was explored. In the absence of an external oxidizing agent, PCE was oxidized over an alumina supported Pt/Rh three-way catalyst. We hypothesize that the chlorine atoms in the adsorbed PCE interact with oxygen in CeO(2), reducing the cerium to create CeCl(3).
