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 impregnation (IWI) method to compare their catalytic performance with the 1-pot synthesized catalysts. The catalysts synthesized by the 1-pot method exhibited higher selectivity of propylene and longer catalyst lifetime at high propane conversion when compared to the counterpart synthesized by the IWI method.
