dc.description.abstract	In this work the effect of Fe addition to copper/ceria catalysts on the catalytic activity toward CO-PROX reaction has been studied and related to the modification of textural and redox properties induced by iron. Catalysts have been characterized by the use of BET surface area measure, X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS) and TPR with different reducing mixtures (CO/N-2 and/or H-2/N-2). Results show that iron promotes a superficial enrichment of highly dispersed copper sites improving catalyst reducibility, especially under CO-containing mixture, thus resulting in an enhanced selectivity of CO-PROX reaction.
