Density functional theory (DFT) calculations were carried out in a study of the oxidation of benzene to phenol by N2O on an Fe2+-ZSM-5 cluster. The catalytic cycle has been studied oil a model [Si6Al2O9H14Fe] cluster. It is found that Fe2+ is preferred over Fe1+ as a site for phenol oxidation. A high desorption value of 126.4 kJ/mol suggests that at low temperature phenol desorption is the rate limiting step on the Fe2+-ZSM-5 cluster. It competes with the N2O decomposition step. The computed activation energy for phenol desorption is in good agreement with the experimental activation energy value of 125.94 kJ/mol reported in the literature for benzene oxidation to phenol by N2O on Fe-ZSM-5.

A Density Functional Theory Study of Direct Oxidation of Benzene to Phenol by N2O on a [FeO](1+)-ZSM-5 Cluster Fellah, Mehmet Ferdi; Önal, Işık; van Santen, Rutger A. (2010-07-29) Density functional theory calculations were carried out in a study of the oxidation of benzene to phenol by N2O on a model (FeO)(1+)-ZSM-5 cluster: the [(SiH3)(4)AlO4(FeO)] cluster. This cluster models the reactivity of Fe3+ oxidic clusters. Results are to be compared with an earlier study (J. Phys. Chem. C 2009, 113, 15307) on a model Fe2+-ZSM-5 cluster. The true activation energies for the elementary reaction step in which phenol is produced appear to be comparable. The major difference between the two sy...
Direct Methane Oxidation to Methanol by N2O on Fe- and Co-ZSM-5 Clusters with and without Water: A Density Functional Theory Study Fellah, Mehmet Ferdi; Önal, Işık (2010-02-25) Density functional theory (DFT) calculations were carried Out ill a Study of oxidation of methane to methanol by N2O on the Fe- and Co-ZSM-5 clusters. The catalytic cycle steps have been Studied oil model Clusters ((SiH3)(4)AlO4M) (where M = Fe, Co). Calculations indicate very low methanol selectivity Without water and increasing rate of methanol formation with water. These results are in qualitative agreement with the experimental literature. The methanol formation step is also found to be the rate-limitin...
A density functional theory study of oxidation of benzene to phenol by N2O on Fe- and Co-ZSM-5 clusters Fellah, Mehmet Ferdi; Önal, Işık (2009-06-01) Density functional theory (DFT) calculations were carried out in the study of oxidation of benzene to phenol by N2O on relaxed [(SiH3)(4)AlO4M] (where M=Fe, Co) cluster models representing Fe- and Co-ZSM-5 surfaces. The catalytic cycle steps are completed for both Fe-ZSM-5 and Co-ZSM-5 clusters. The general trend of the results that were obtained in terms of activation barriers for the Fe-ZSM-5 cluster is in agreement with the experimental and theoretical literature. It was observed that the phenol formatio...
A DFT Study of Direct Oxidation of Benzene to Phenol by N2O over [Fe(mu-O)Fe](2+) Complexes in ZSM-5 Zeolite Fellah, Mehmet Ferdi; Pidko, Evgeny A.; van Santen, Rutger A.; Önal, Işık (2011-05-19) Density functional theory (DFT) calculations were carried out in a study of the mechanism of benzene oxidation by N2O to phenol over an extra framework dimeric [FeOFe](2+) species in ZSM-5 zeolite represented by a [Si6Al2O9H14(Fe(mu-O)Fe)] cluster model. The catalytic reactivity of such a binuclear species is compared with that of mononuclear Fe2+ and (FeO)(+) sites in ZSM-5 investigated in our earlier works at the same level of theory (J. Phys. Chem. C 2009, 113, 15307; 2010, 114, 12580). The activation en...
Activation of light alkanes on pure and Fe and Al doped silica clusters: A density functional and ONIOM study

Fellah, Mehmet Ferdi; Önal, Işık (2007-01-01)

C-H bond activation was studied by use of density functional theory (DFT) and ONIOM calculations as implemented in Gaussian 2003 at the B3LYP level utilising 6-31G* as the basis set for Si, Al, and Fe atoms and 3-21G** as the basis set for O and H atoms. Relative energy profiles were determined for pure silica modeled by a Si7O21 cluster and Fe and Al doped silica clusters via coordinate driving calculations. The activation barriers for C-H bond activation of methane and ethane decrease with the substitutio...
