摘要：

Dehydrogenation of ethylbenzene to styrene with carbon dioxide has been investigated using various vanadia-alumina catalysts to exhibit high activity and selectivity. Redox behavior of vanadium oxide played a key role in the dehydrogenation. Among several additives, antimony oxide has been found for improving catalyst stability as well as catalytic activity to produce styrene, revealing that the addition of the antimony oxide leads to the easier redox cycle between fully oxidized and reduced vanadium species.
