Abstract

A Pd catalyst (Pd/Ce_0.7Zr_0.3O₂) in an electric field exhibits extremely high three-way catalytic activity (TWC: NO-C₃H₆-CO-O₂-H₂O). By applying an electric field to the semiconductor catalyst, low-temperature operation of TWC can be achieved even at 473 K by virtue of the activated surface-lattice oxygen.
