| Abstract: | A series of CuO–CeO2 catalysts have been prepared by different methods and the effects of interaction
between CuO and CeO2 on the performance of CuO-CeO2 catalysts for selective oxidation of CO in H2-rich
streams have been investigated. The results show that HY-CuO-CeO2 with strong interaction and synergistic effect between
interfacial CuO and CeO2 exhibits superior
catalytic activity, especially at low temperatures. For HY-CuO-CeO2, the temperature of 50 % CO conversion is only 75 °C and the temperature window of CO conversions
up to 99.0 % is about 30 oC wide, from 120–140 °C. The strong interaction between
copper and cerium oxide promotes the reduction of highly dispersed
CuO species, the formation and stability of abundant Cu+ species and
the production of abundant oxygen vacancies and lattice oxygen of copper oxide. |
