Electrical promotion-assisted automotive exhaust catalyst: highly active and selective NO reduction to N at low-temperatures
A Pd catalyst (Pd/Ce 0.7 Zr 0.3 O 2 ) in an electric field exhibits extremely high three-way catalytic activity (TWC: NO-C 3 H 6 -CO-O 2 -H 2 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 sur...
