| Abstract: | The spinel ferrites were prepared by the wet-method of air-oxidation and characterized by XRD, IR, UV-DRS and TPR method. The catalytic activity of oxidative dehydrogenation of ethylbenzene to styrene with carbon dioxide over the spinel ferrites was studied. And the relationships among catalytic activity, composition, structure and the action of carbon dioxide were also discussed. |

| Keywords: | spinel ferrites structure redox catalytic activity ethylbenzene dehydrogenation |
