In Situ Confocal Microprobe Raman Spectroscopy Study of the Oxygen Species over Cerium Oxide
摘要:
In situ confocal microprobe Raman spectroscopy results showed that O22-, O2- and O2δ- (0 <δ< 1) adspecies formed on the O2 pretreated cerium oxide sample when the temperature was below 423 K.At 1023 K, only CeO2 F2g peak (at 449 cm-1) and O2- species (at 1159 cm-1) were observed on the surface.The reactivity of methane with the oxygen species was lower than that of ethane with the oxygen species.
