Propane oxidative dehydrogenation over vanadium oxide nanostructures supported on porous graphene prepared by hydrothermal method

Abstract

In this study at first, in laboratory, three types of vanadium oxide were produced by using porous graphene and amine framework in hydrothermal method nanostructures such as: vanadium oxide - octadecyl amine - graphene, vanadium oxide - dodecyl amine - graphene and vanadium oxide – aniline - graphene (V-ODA-G، V-DDA-G، V-A-G). Then their structures and functions in propane dehydrogenation reactions were studied and productivity and efficiency of these catalysts in mentioned reactions were compared with each other. In order to notice and compare the structures and properties of synthesized catalysts, some methods such as Field Emission Scanning Electron Microscope (FE-SEM), X Ray Diffraction (XRD), Thermo Gravimetric Analysis (TGA), Fourier Transform Infrared Spectrometry (FTIR), Gas Chromatography (GC) have been used. The obtained results show that vanadium oxide nanostructures have great opportunities to be oxidatively dehydrogenation (ODH) and make sciences explore the use of porous grapheme as catalysts for propane oxidative dehydrogenation.
