Dehydrogenation Mechanism in Flavoprotein Catalysis

I "C -X-H+Acc(ox)--> C =X+Acc(red)H 2 I / H This type of reaction should be differentiated from the oxygenase reaction, in which the substrate electrons are transferred directly to oxygen. The limiting chemical step of the dehydrogenation, i.e., the rupture of the kinetically stable substrate C-H bond, is catalyzed by enzymes which have either pyridine nucleotide, pyridoxal-phosphate, flavin-, ...

Oxidative dehydrogenation of 9,10-dihydroanthracene using multi-walled carbon nanotubes

Multi-walled carbon nanotubes (MWCNTs) have been used in the oxidative dehydrogenation of 9,10-dihydroanthracene in an organic solvent (toluene) using molecular oxygen as the oxidant, and in the absence of trace amounts of metals. The process is very selective and almost no anthraquinone is formed. Thermal treatment of the MWCNTs at 2600 °C favors deoxygenation of the support and markedly impro...

Heterogeneous Partial (amm)Oxidation and Oxidative Dehydrogenation Catalysis on Mixed Metal Oxides

This paper presents an overview of heterogeneous partial (amm)oxidation and oxidative dehydrogenation (ODH) of hydrocarbons. The review has been voluntarily restricted to metal oxide-type catalysts, as the partial oxidation field is very broad and the number of catalysts is quite high. The main factors of solid catalysts for such reactions, designated by Grasselli as the “seven pillars”, and pl...

Surface-modified carbon nanotubes catalyze oxidative dehydrogenation of n-butane.

Butenes and butadiene, which are useful intermediates for the synthesis of polymers and other compounds, are synthesized traditionally by oxidative dehydrogenation (ODH) of n-butane over complex metal oxides. Such catalysts require high O2/butane ratios to maintain the activity, which leads to unwanted product oxidation. We show that carbon nanotubes with modified surface functionality efficien...

Toward Low-Temperature Dehydrogenation Catalysis: Isophorone Adsorbed on Pd(111).

Adsorbate geometry and reaction dynamics play essential roles in catalytic processes at surfaces. Here we present a theoretical and experimental study for a model functional organic/metal interface: isophorone (C9H14O) adsorbed on the Pd(111) surface. Density functional theory calculations with the Perdew-Burke-Ernzerhoff (PBE) functional including van der Waals (vdW) interactions, in combinati...
