Dehydrogenation by Heterogeneous Catalysts

Catalytic dehydrogenation of isopentane with iridium catalysts.

The catalytic activation of alkanes under mild conditions to give the corresponding alkenes and hydrogen has tremendous industrial implications because olefins are the most important starting materials for large-scale industrial processes such as olefin polymerization, dimerization, oligomerization, hydroformylation, and metathesis. In the search for a process by which olefins can be produced f...

Tandem ammonia borane dehydrogenation/alkene hydrogenation mediated by [Pd(NHC)(PR3)] (NHC = N-heterocyclic carbene) catalysts.

[Pd(NHC)(PR(3))] complexes were shown to be active catalysts in the dehydrogenation of ammonia borane and the subsequent hydrogenation of unsaturated compounds at very low catalyst loadings (0.05 mol% for some substrates).

Novel and Effective Copper–Aluminum Propane Dehydrogenation Catalysts

The importance of solid catalysts for converting petroand bulk chemicals is reflected in the sheer magnitude of their market size: catalysts sales topped nine billion dollars in 2009. This large value mirrors also the increasing academic interest in heterogeneous catalysis research. As far as bulk chemicals (such as ethene, propene, and their derivatives) are concerned, there is a strong demand...

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...
