N2 - Mesoporous cerium dioxide has been synthesized using the ordered mesoporous silica KIT-6 as hard template. A series of different amounts of CuO have been modified to this CeO2 replica by wet impregnation. The XRD, SEM, TEM, N2 sorption measurement, and the CO catalytic oxidation reaction have been adopted to characterize those materials. CuO can be homogeneously loaded on this ceria replica. Compared with the porous CeO2 directly decomposed from the cerium nitrate hydrate, this CeO2 shows high catalytic reactivity for the CO oxidation, the T50 on this ceria replica is 83 K lower than on the decomposed ceria, and the CuO-loaded mesoporous ceria show more active for this catalytic reaction, the lowest T50 is only 389 K achieved at the 20% CuO loading.
