Abstract

By an acid-catalyzed sol–gel method the V-doped titanium oxides (VxDTOs, x mol% of V/(V + Ti) molar ratio) were prepared and systematically characterized by the techniques of XRD, TEM, H2-TPR, XPS and TGA, indicating that most of the vanadium in the catalyst was highly dispersed on the surface of and in the bulk phase of TiO2. The effect of V5+ doping level (1–9 mol% V5+) on the surface of TiO2 and VxDTOs catalytic performance was analyzed. From the catalytic activity evaluation of VxDTOs in the dehydrogenation of ethylbenzene to styrene in the presence of CO2 (CO2-EBDH) at 450 °C, V6DTOs catalyst had the highest activity. Its higher activity in CO2 than in N2 clearly shows that CO2 markedly enhanced the dehydrogenation of ethylbenzene. The activity of V6DTOs catalyst could almost be resumed after regeneration by air while partly resumed after regeneration by CO2.
