Abstract: | Neodymium-doped Ceria (NDC, Nd = 0, 1, 3, 5, 10, 20 and 30 mol %) catalysts were successfully synthesized by Glycine-Nitrate-Process (GNP) and tested for soot oxidation activity. For all NDC catalysts, XRD and Raman spectroscopy analyses showed a fluorite structure of ceria having an F2gRaman active symmetric breathing mode (O-Ce-O). 1NDC catalyst displayed better T50 temperature (427?C) followed by 0NDC (435?C), and 30NDC showed the highest T50 temperature (460?C). From XPS analysis, 1NDC and 0NDC catalysts showed a high amount of Ce3+ concentration and the surface-active oxygen species than compared to other NDC catalysts and thus, resulted in better soot oxidation activity indicating that the surface Ce3+ concentration and surface-active oxygen species play a key descriptor role in tuning the soot oxidation activity of NDC catalysts. 2019 Elsevier B.V. |
