%X This article reviews work done at authors¡¯ laboratories about catalysts based on combinations between copper and ceria for preferential oxidation of CO in H 2-rich streams (CO-PROX). The main focus of this review is the characterization of active sites for the process on the basis of spectroscopic analysis of the systems under reaction conditions ( operando techniques). On such a basis, it is exposed the state of the art in this field in connection with results obtained in other laboratories.
