One-pot synthesis of VO _x /Al ₂ O ₃ as efficient catalysts for propane dehydrogenation.

ABSTRACT: Vanadium oxides, as highly efficiently catalysts, are widely applied in various catalytic reactions, such as the dehydrogenation of light alkanes and epoxidation of alkenes. In this paper, a series of VO _x /Al ₂ O ₃ catalysts were fabricated by the 1-pot method for catalytic propane dehydrogenation. The results indicated that the VO _x /Al ₂ O ₃ catalysts with loading of 10 wt.% vanadium exhibited optimized catalytic performance. The as-prepared catalysts were characterized by N ₂ adsorption-desorption, XRD, TEM, H ₂ -TPR, and XPS to explore the texture properties, morphology, and electronic environment of vanadium. In addition, several vanadium catalysts were also prepared by the incipient wetness impre
