abstract = {A series of oxidised copper-cerium nanostructured catalysts prepared by impregnation of copper over
ceria supports synthesized by different methods (hydrothermal with varying preparation parameters,
microemulsion/precipitation), in order to achieve different specific morphologies (nanocubes, nanorods
and nanospheres), have been examined with respect to their catalytic properties for preferential oxidation
of CO in excess H2 (CO-PROX). The catalysts have been characterized in detail by XRD, Raman, SBET
measurement, HREM, XPS, TPR and EPR, which allows establishing a model of structural characteristics
of the catalysts. The characterization results have been correlated with analysis of CO-PROX catalytic
properties by means of catalytic activity measurements complemented by operando-DRIFTS. Structural
dependence of the CO oxidation reaction on the dispersed copper oxide entities as a function of the
exposed face present at the surface of the different ceria supports is revealed. An important overall
enhancement of the CO-PROX performance is detected for the sample supported on ceria nanocubes
which is proposed to be a consequence of the interaction between copper oxide and (1 0 0) faces of the
ceria support.},
