| Abstract: | TPR processes of Fe-Ce oxides were studied by in situ Mossbauer spectroscopy and XRD. Three peaks were observed in the TPR profile of the sample, indicating the three reduction stages of the Fe-Ce oxide. The raise of the avtivation energy and temperature of the reduction reaction of the oxides with H2 were the evidence of strong interactions of metal ions in oxides. |
