A moment technique was developed for the investigation of adsorption on metal surfaces of supported catalysts. The technique was applied to the evaluation of adsorption rate parameters of CO on a Pt-Al2O3 washcoated monolith. The adsorption rate constants evaluated in the temperature range 273-316 K showed significant decrease with an increase in surface coverage. Results of pulse response experiments corresponding to zero coverage gave the apparent activation energy for adsorption as 21 kJ/mol. This method allowed the evaluation of adsorption rate constant on metal sw-faces at different coverages.

A quantum chemical study of water and ammonia adsorption mechanisms on titanium dioxide surfaces

Erdoğan, Rezan; Önal, Işık; Department of Chemical Engineering (2010)

Theoretical methods can be used to describe surface chemical reactions in detail and with sufficient accuracy. Advances, especially in density functional theory (DFT) method, enable to compare computational results with experiments. Quantum chemical calculations employing ONIOM DFT/B3LYP/6-31G**-MM/UFF cluster method provided in Gaussian 03 are conducted to investigate water adsorption on rutile (110), and water and ammonia adsorption on anatase (001) surfaces of titanium dioxide. Water and ammonia adsorpti...
The effects of alkali promoters on the dynamics of hydrogen chemisorption and syngas reaction kinetics on Ru/SiO2 surfaces Üner, Deniz; Pruski, M; King, TS (1997-01-01) The dynamics of chemisorbed hydrogen on unpromoted and promoted Ru/SiO2 catalysts was studied by means of single pulse and selective excitation H-1 NMR spectroscopy. Dynamic NMR studies indicated a reduced mobility of hydrogen in the presence of alkali promoters (Na and K) at high loadings (65 atomic %). On unpromoted Ru/SiO2 catalysts, the line due to hydrogen-on-metal was homogeneously broadened at pressures above 0.5 Torr H-2. Similar behavior was observed on promoted Ru/SiO2 catalyst with 66 atomic % K....
A study of catalytic nanocarbon synthesis by means of quantum mechanical methods Tezsevin, İlker; Önal, Işık; Department of Chemical Engineering (2012) Throughout this thesis work, surface nanocarbon synthesis on metal catalyst surfaces was investigated as the first step of carbon nanotube production mechanism. Study was aimed to make a comparison between the performances of selected catalyst surfaces and to find most probable mechanism for the nanocarbon synthesis on the metal catalyst surface. Formation of nanocarbon from the acetylene as carbon source on the selected Fe(111), Ni(111) and Ni(100) surfaces were studied by means of quantum mechanics. Densi...
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...
A quantum chemical study of nitric oxide reduction by ammonia (SCR reaction) on V2O5 catalyst surface

Soyer, Sezen; Uzun, Alper; Senkan, Selim; Önal, Işık (2006-12-15)

The reaction mechanism for the selective catalytic reduction (SCR) of nitric oxide by ammonia on (010) V2O5 surface represented by a V2O9H8 cluster was simulated by means of density functional theory (DFT) calculations performed at B3LYP/6-31G** level. The computations indicated that SCR reaction consisted of three main parts. For the first part, ammonia activation on V2O5 was investigated. Ammonia was adsorbed on Bronsted acidic V-OH site as NH4+ species by a non-activated process with an exothermic relati...
