A CuO-CeO₂/MCF catalyst was prepared by cyclodextrin-assisted co-impregnation (CC/M-CD). For comparison, a reference catalyst was prepared by traditional wet impregnation (CC/M). The catalysts were characterized by ICP-OES, XRD, Raman, N₂-physisorption, TEM, EDS mapping, XPS, in situ DRIFTS, H₂-TPR, and CO-TPD. The results show that Cu and Ce species of the CC/M-CD catalyst disperse more homogeneously, and the CC/M-CD catalyst has a larger surface area, more amounts of Cu⁺ and Ce³⁺ species, enhanced interaction between CuO and CeO₂, and thus exhibits higher catalytic activity in CO oxidation. Additionally, the kind and amount of cyclodextrin used in the impregnating solutions have no distinct effect on the activity of CC/M-CD prepared by the cyclodextrin-assisted co-impregnation.

通过环糊精辅助共浸渍（CC / M-CD）制备了CuO-CeO ₂ / MCF催化剂。为了比较，通过传统的湿法浸渍（CC / M）制备了参考催化剂。通过ICP-OES，XRD，拉曼，N _2-物理吸附，TEM，EDS作图，XPS，原位DRIFTS，H ₂ -TPR和CO-TPD对催化剂进行了表征。结果表明，CC / M-CD催化剂中的Cu和Ce物种分散更均匀，CC / M-CD催化剂具有更大的表面积，更多的Cu ⁺和Ce ³⁺物种，增强了CuO与Cu之间的相互作用。铈₂，因此在CO氧化中表现出更高的催化活性。另外，在浸渍溶液中使用的环糊精的种类和数量对通过环糊精辅助共浸渍制备的CC / M-CD的活性没有明显的影响。
