Abstract
Abstract The behaviour of a series of Palladium and Palladium-Copper catalysts supported on ceria/alumina and ceria-zirconia/alumina for the CO+NO+O 2 reaction has been analysed by a combination of Electron Transmission Microscopy, Infrared and Electron Paramagnetic spectroscopies and catalytic test studies. In both systems, the catalytic behaviour is dominated by the properties of the Metal-Support Interface. While Palladium systems show a similar behaviour in both types of supports, Cu only modifies the behaviour of the ceria/alumina- supported one.
