摘要：

Surface and bulk oxygen vacancy defects in ceria powder samples were investigated by Raman. UV-vis and X-ray photoelectron spectroscopy combined in one experimental setup for the first time. Analysis of surface reduction (defects) is based on changes in Ce3d photoemission lines. For ceria reduced by X-ray exposure UV-vis spectra reveal an electronic transition at around 500 nm. The nature of the defects is specified by the presence of peroxide and hydroxy Raman bands at 832 cm(-1) and 3664 cm(-1). Our results demonstrate the potential of a combined spectroscopic approach for characterization of defects located at the surface and in the bulk of ceria. (C) 2012 Elsevier B.V.
