Abstract: Using the procedure of oncoming precipitation the Pd/CeO2-SnO2 catalysts for low temperature CO oxidation were synthesized for the first time. These catalysts are characterized by high activity with unusually high thermal stability at temperatures up to 1000 °C. Formation of microdomain structure is shown to provide high thermal stability of catalytically active phases including the surface PdOx(s)/Pd–O–Ce(s) species which determine the reaction rate.
