英文摘要	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 m² g⁻¹) and ordered mesopore. The research results showed that Co₃O₄, CuO, Fe₂O₃ crystallites in catalysts were encapsulated 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-dimensional mesoporous structure, resulting in unique redox properties. The research results showed that the introduction of promoter (Co, Cu and Fe species) could effectively enhance the chemisorbed oxygen and oxygen vacancy concentration on the surface of metal-doped CeO₂ catalysts. Compared with Co and Fe species, the Cu species had an obvious enhancement. The characteristic was relatively 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.
