Oxydehydrogenation of Propane over Vanadium Oxide Supported on Kieselguhr or MCM-41

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

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 react...

Vanadium Oxide Supported on Al-modified Titania Nanotubes for Oxidative Dehydrogenation of Propane

In this study, characterization of vanadia supported on Al-modified titania nanotubes (TiNTs) synthesized by the alkaline hydrothermal treatment of TiO2 powders has been reported. A promising catalyst for oxidative dehydrogenation (ODH) of propane was prepared via the incipient wetness impregnation method. The morphology and crystalline structure of TiNTs were characterized by transmission elec...

Vanadium oxide surfaces and supported vanadium oxide nanoparticles

The information obtained from the characterization of vanadium oxide single crystal surfaces is related to the study of vanadia nanoparticles supported on silica and alumina thin films, model systems for the so-called ‘‘supported monolayer vanadia catalysts’’. It is found that these particles have properties similar to V2O3 surfaces, where the topmost V ions are involved in vanadyl groups and h...

Anomalous reactivity of supported V2O5 nanoparticles for propane oxidative dehydrogenation: influence of the vanadium oxide precursor.

The oxidative dehydrogenation (ODH) of propane to propylene by supported vanadia catalysts has received much attention in recent years, but different reactivity trends have been reported for this catalytic reaction system. In the present investigation, the origin of these differing trends are investigated with synthesis of supported V/SiO2, V/TiO2, and V/Al2O3 catalysts prepared with three diff...
