Abstract
Stabilized palladium (+1) compounds to mimic rhodium's electronic configuration and catalytic properties are disclosed. Palladium (+1) compounds may be stabilized in perovskite or delafossite structures and may be employed in Three-Way Catalysts (TWC) for at least the conversion of HC, CO and NOx, in exhaust gases. The TWC may include a substrate, a wash-coat and, a first impregnation layer, a second impregnation layer and an over-coat. The second impregnation layer and the over-coat may include palladium (+1) based compounds as catalyst.
