CeO2 decorated CuO hierarchical composites as inverse catalyst for enhanced CO oxidation

Abstract

CuO microspheres were constructed with self-assembled CuO nanosheets through a hydrothermal method. Then, CeO2 nanoplatelets were decorated on the surface of CuO nanosheets to obtain inverse CeO2/CuO catalysts. The catalysts were characterized by using XRD, SEM, HRTEM, XPS, Raman spectroscopy, and H2-TPR techniques. It was found that the CeO2/CuO inverse catalysts had a hierarchical structure and a much lower 100% CO conversion temperature than that of CuO microspheres. A model of the structure and catalytic effect based on the contact interface between CeO2 and CuO is discussed. The two-dimensional CuO nanosheets and CeO2 nanoplatelets were most favorable for the formation of long periphery at the CeO2/CuO interface, therefore, enhanced catalytic activity was achieved.
