Description:
A series of V-MCM-41 were in situ synthesized. The textual properties and vanadium species were systematically characterized. The results showed that the catalysts could still maintain mesoporous structure and high specific surface area. The vanadium species were highly dispersed on the surface while polymeric vanadium species co-existed. The iso-butane dehydrogenation was performed by employing CO 2 as soft oxidant. The results revealed an almost linear relationship between the activity and surface vanadium sites. Isolated vanadium species were more active for iso-butane dehydrogenation. The iso-butane dehydrogenation reaction in the presence of CO 2 could proceed simultaneously via oxidative dehydrogenation and non-oxidative dehydrogenation followed by the reverse water gas shift reaction.
