Y. Sakurai et al., Oxidation capability of carbon dioxide in the dehydrogenation of ethylbenzene over vanadium oxide-loaded MgO catalyst, CHEM LETT, (5), 2000, pp. 526-527
Carbon dioxide could oxidize the reduced vanadium oxide species on MgO and
keep vanadium species at a high oxidation state, during the dehydrogenation
of ethylbenzene to styrene under carbon dioxide, giving a markedly high yi
eld and selectivity of styrene.
