Pd catalyst (Pd/Ce<sub>0.7</sub>Zr<sub>0.3</sub>O<sub>2</sub>) in an electric field exhibits extremely high three-way catalytic activity (TWC: NO-C<sub>3</sub>H<sub>6</sub>-CO-O<sub>2</sub>-H<sub>2</sub>O). 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.
