摘要：

Cu-CeO2 catalysts deposited on a commercial ZrO2 support have been investigated. The catalyst composition has been optimized: the optimum copper content was found to be 5-10 wt % at a cerium oxide content of 23 wt %. The catalysts were investigated by X-ray diffraction analysis and X-ray photoelectron spectroscopy. According to the X-ray diffraction data, the support consists of the monoclinic ZrO2 phase and cubic CeO2 phase with an enlarged lattice parameter, while the catalysts contain CuO. The X-ray photoelectron data indicate the presence of a highly dispersed CuO2 phase interacting with cerium oxide and zirconia on the surface of the catalyst having the optimum copper content. © Allerton Press, Inc. 2008.
