Unusually shaped silica streamlines hydrogenation for organic synthesis

Hydrogenation of hydrocarbons by heterogeneous catalysts is well studied and commercialized. Usually, a standard industrial catalyst consists of precious metal deposited on different kinds of supports (e.g carbon or metal oxide). Nevertheless, the development of a new type of support offers the potential for improvements in catalytic performance for research and commercial applications.

Recently the successful application of fibrous shaped KCC-1 silica nanoparticles with unique physical properties (Fig 1) [1], for energy related processes has been reported. There has been much interest in supports with high surface area and good thermal stability, which has attracted  attention from organic chemists.

Hydrogenation of alkenes and α, β-unsaturated carbonyl compounds have been studied using an efficient palladium supported KCC-1 based catalyst. A superior performance result of KCC-1 in comparison to other commercial mesoporous silica gives  excellent yields of products with very high chemo-selectivity in the case of unsaturated carbonyl compounds [2]. Dimethyl oxalate (DMO) was successfully hydrogenated to methylene glycol (MG) by silver supported KCC-1 catalyst. The authors conclude that KCC-1 with hierarchical pore channels has higher accessible internal surface area and therefore displays stronger catalytic activity [3].

A hydro-metathesis reaction has been performed by tantalum hydride grafted on KCC-1 [4]. The catalyst is able to transform an olefin in the presence of hydrogen at moderate temperatures into the expected corresponding alkane, as well as transform the same olefin into alkanes with a higher and lower number of carbon atoms.

KCC-1 based catalysts are also effectively utilized in the hydrogenation of functionalized aromatic compounds [5], hydrogenolysis of alkanes [6] and many other processes. For more detailed information, please review our Strem Chemiker dedicated to the KCC-1 silica nanoparticles.
