“…Our present activity evaluation results show that the CuO/CeO 2 -nanorods are more active than the CuO/CeO 2 -nanoparticles. These activity trends are in good agreement with the results obtained by Ska˚rman et al [16]. Moreover, the TPR analysis reveals more favorable synergetic effect between CuO and ceria nanorods compared to the nanoparticles.…”

“…And the nanorods exhibit more stable facile redox properties than the nanoparticles. Through the rf magnetron sputtering method, Ska˚rman et al [16] had successfully prepared two types of ceria films, one with exclusively of {111} type planes and the other with {001} planes. And they reported that the activity of copper oxide supported on {001} planes of CeO 2 film is higher than on {111} planes.…”

“…This implies the CeO 2 nanorods may perform better than the ''classical'' nanoparticles in assisting the Cu 2+ /Cu + (Cu 0 ) couples [16]. Herein, we report a comparative study of CeO 2 nanorods and nanoparticles as supports for CuO catalysts.…”

“…Our observed activation energies were in fairly good agreement with the literature reports [27,29,[46][47][48]. Although for the different doped metals on the different supports, the activation energies were rather deviated from our results [49][50][51][52][53][54][55], but in good agreement with same oxide support and the doped metal. Especially, for Au/ CeO 2 catalysts reported by Arena et al [45].…”

CO oxidation to CO 2 by Pd-CeO 2 catalysts was tested by temperatureprogrammed mass spectrometry for as-prepared and thermal H 2 -treated Pd-doped CeO 2 catalysts, compared with those of Ag and Au-doped CeO 2 . For the as-prepared samples, the oxidation rate and the T 10 % (the temperature at 10 % CO conversion) occurred in the order of Au & Pd [ Ag ) undoped in the 1st CO oxidation run, while in the 2nd run, the order became Au [ Pd [ Ag ) undoped. For the thermal H 2 -treated samples, the order became Pd [ Au [ Ag [ undoped and Au [ Pd [ Ag [ undoped in the 1st and 2nd CO oxidation runs, respectively. The T 10 % in the 2nd run commonly occurred at much lower temperatures for the metal-doped CeO 2 upon achieving good metal-oxide interfacial contact during the 1st run. The T 10 % of undoped CeO 2 was the most significantly affected by the thermal treatment effects while those of metal-doped CeO 2 catalysts were not greatly affected by the thermal H 2 -treatment. Based on these findings, the metal-support interaction/interface is more important than the surface area, Au (88 m 2 /g) [ Ag (59 m 2 /g) & Pd & undoped.
