摘要: An Ir-in-ceria catalyst has been developed, in which most of the iridium particles were embedded in the ceria matrix. This Ir-in-ceria catalyst exhibited high activity for preferential CO oxidation under excess hydrogen conditions, and the selectivity to CO oxidation remained nearly constant with increasing reaction temperature. It was found that the CeO2 support was properly activated by iridium and acted as the active sites for CO oxidation. Due to the absence of extensively exposed Ir species in the Ir-in-ceria catalyst, H2 oxidation occurring on the Ir species and the ceria support at high temperatures was significantly suppressed, thus keeping the selectivity to CO oxidation at a high level.
