Role of ceria in oxidative dehydrogenation on supported vanadia catalysts.
The effect of the suppport on oxidative dehydrogenation activity for vanadia/ceria systems is examined for the oxidation of methanol to formaldehyde by use of well-defined VO(x)/CeO(2)(111) model catalysts. Temperature-programmed desorption at low vanadia loadings revealed reactivity at much lower temperature (370 K) as compared to pure ceria and vanadia on inert supports such as silica. Densit...

is not favorable (AH = + 3 1.5 kcal). Our conclusion is that an important catalytic site involves two adjacent surface dioxo units (the dual dioxo site), with each dioxo site extracting one H in a sequence of steps. The required dual dioxo site exists on the (010) surface of MOO, but does not exist on the other low index surfaces. This mechanism is supported by atmospheric pressure experimental...
متن کاملAuto‐Tandem Catalysis: PdII‐Catalysed Dehydrogenation/Oxidative Heck Reaction of Cyclopentane‐1,3‐diones
A PdII catalyst system has been used to successfully catalyse two mechanistically distinct reactions in a one-pot procedure: dehydrogenation of 2,2-disubstituted cyclopentane-1,3-diones and the subsequent oxidative Heck coupling. This auto-tandem catalytic reaction is applicable to both batch and continuous flow processes, with the latter being the first example of a tandem aerobic dehydrogenat...
متن کاملVanadium 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...
متن کاملOperating condition effect on achieving higher propene yield in propane oxidative dehydrogenation process
Supported vanadia catalyst was successfully synthesized using wet impregnation of gamma-Alumina to study Propane Oxidative Dehydrogenation (POD). The prepared catalysts were characterized with XRD, BET, and TPR tests. In a broad temperature range (340 to 630°C), effects of vanadia loading (2.7, 5.4, and 9 wt%) and propane to oxygen ratio (3/1 to 1/3) were investigated on propane conversion as w...
