摘要：

This work shows that carbon dioxide, which is a main contributor to the global warming effect, could be utilized as a selective oxidant in the oxidative dehydrogenation of ethylbenzene over alumina-supported vanadium oxide catalysts. The modification of the catalytically active vanadium oxide component with appropriate amounts of antimony oxide led to more stable catalytic performance along with a higher styrene yield (76%) at high styrene selectivity (> 95%). The improved catalytic behavior was attributable to the enhanced redox properties of the active V-sites.
