| Abstract: | The catalyst used in the selective oxidation dehydrogenation of ethylbenzene to styrene with carbon dioxide was reviewed. Reserachers made much progress in this processs,however, the catalyst deactivated very soon and its stability was lowly. It was important for the application of this process to improve the catalyst activation, especially enhance their catalytic stability by further investigating the mechanism of catalyst and deactivation. |
