✦ Synopsis
The CuOeCeO 2 eMeO x (Me ¼ Zr, Ti, Mn, Al; x ¼ 1.5e2) solids were tested in the preferential CO oxidation reaction in hydrogen-rich gas mixtures (PROX). We study an effect of a support (MeO x ) the CO conversion and selectivity in the PROX reaction showing that monoclinic zirconia (m-zirconia) with low surface area is the most effective support. The optimal catalyst composition was determined by varying copper and ceria loadings over m-zirconia. XRD and XPS studies indicate that a good catalytic performance of m-zirconia supported coppereceria catalysts may be attributed to the presence of dispersed Cucontaining species that interact with CeO 2 and ZrO 2 .
