- W3143388342 abstract "Transition metal (Co, Cu, Fe)-doped CeO2 catalysts with three-dimensional mesoporous channels had been synthesized through a nanocasting route using three- dimensional mesoporous silica KIT-6 as the template. All four catalysts exhibited high surface area ((120 m 2 g -1 ) and ordered mesopore. The research results showed that Co3O4, CuO, Fe2O3 crystallites in catalysts were encap- sulated by nanosized CeO2, respectively, and a small fraction of Co, Cu, Fe ions were exposing on the surface and strongly interacting with CeO2. These ions (Co, Cu, Fe) maximized interaction with Ce ion in three-dimen- sional mesoporous structure, resulting in unique redox properties. The research results showed that the introduc- tion of promoter (Co, Cu and Fe species) could effectively enhance the chemisorbed oxygen and oxygen vacancy concentration on the surface of metal-doped CeO2 cata- lysts. Compared with Co and Fe species, the Cu species had an obvious enhancement. The characteristic was rela- tively conducive to the catalytic oxidation of CO. The catalysts were evaluated for the catalytic oxidation CO reaction. The Cu-doped CeO2 catalyst exhibited the highest catalytic activity, and complete conversion temperature (T100) was about 50 C for CO oxidation." @default.
