Dispersion Behaviors of Copper Oxide on the Mixed “CeO2+ γ-Al2O3” Support
Source abstract
Abstract
The dispersion behaviors of copper oxide on the mechanical mixture of CeO 2 and γ-Al 2 O 3 supports, CuO/CeO 2 + γ-Al 2 O 3, have been characterized by using XRD, LRS, XPS, UV-DRS, and TPR. The results show that copper oxide dispersed mainly on the surface of CeO 2 support, provided that the loading amount of copper oxide does not exceed the dispersion capacity of CuO/CeO 2, ∼1.2 mmol of CuO/100 m 2 of CeO 2 (Dong, L.; Jin, Y. S.; Chen, Y. Sci. China (B). 1997, 40, 24). Increasing the CuO loading evidently leads to the formation of the dispersed copper oxide species on the surface of the γ-Al 2 O 3 support. The results have been tentatively discussed by using the incorporation model, which was proposed to describe the interaction between the dispersed species and the support previously (Chen, Y.; Zhang, L. F. Catal. Lett. 1992, 12, 51).
