Modeling catalytic effects of clay mineral surfaces on peptide bond formation

Article Abstract:

A study was conducted, with density functional theory calculations, to investigate the catalysis of the amide-bond formation for the concerted reaction of acetic acid and methylamine on clay mineral surfaces. The result reveals a strong asynchronous mechanism with the prior formation of a N-C dative bond, followed by a proton transfer from nitrogen to oxygen as the rate-determinig step.

Physiochemical and catalytic properties of copper ethylenediamine complex encapsulated in various zeolites

Article Abstract:

The interaction of copper ethylenediamine encapsulated in various zeolites is dependent on the nature of the zeolite. It is shown that by changing the redox potential of a given metal complex, which is inactive for a particular reaction under a given set of conditions, one can make it an active catalyst and also provides a vital clue for generating biometic systems in the future.

In-situ observation of reaction intermediate in the selective catalytic reduction of N2O with CH4 over Fe ion-exchanged BEA zeolite catalyst for the elucidation of its reaction mechanism using FTIR

Article Abstract:

A systematic in-situ FTIR study on the formation and reaction of adsorbed species in N2O reduction by CH4 over Fe-BEA catalyst is carried out. In effect, it is proposed that N2O plays an important role in the initial steps (reaction with CH4 to form methoxy species) on the selective catalytic reduction (SCR) of N2O with CH4.
