%X The styrene synthesis is one of the ten largest industrial processes. This monomer is involved in several polymer syntheses, and is industrially produced by the direct dehydrogenation of ethylbenzene at 873953 K over a potassium promoted iron oxide catalyst [1]. This strongly endothermic process suffers from drawbacks such as thermodynamic limitations, a large amount of wasted energy, an irreversible catalyst deactivation and coke deposition [2]. Among the alternative technologies developed, the exothermic and non-thermodynamically-limited oxidative dehydrogenation (ODH) of ethylbenzene is promising. Carbon is reported to be catalytically active for the reaction [3] and [4]. It has been shown that high performances could be obtained over onion-like carbons and carbon nanotubes [5], [6], [7] and [8], such non-planar sp2-nanocarbons being very active and promising alternative catalysts to the industrial catalyst, with a higher styrene yield and a lower reaction temperature. The nanocarbons also remained more stable against combustion in an oxidative atmosphere than active carbon [7] and [8]. A redox mechanism at the carbon surface has been put forward [4], [5], [6], [7], [8] and [9], involving the oxygen activation on metallic basal planes and the ethylbenzene dehydrogenation on nucleophilic Bronsted basic C=O groups at the edge/kink sites [6] and [7].
