Characterization and temperature-programmed studies were performed over Pd/titania catalysts to examine their activity in the reduction of NO with methane. The catalyst was prepared using a wet impregnation technique and Pd-acetate was used as a precursor for palladium. Techniques such as BET surface area measurements, X-ray diffraction, laser Raman spectroscopy, X-ray photoelectron spectroscopy, and scanning electron microscopy were used for the characterization of the catalyst before and after the reaction. Temperature-programmed reduction (TPR) and temperature-programmed desorption (TPD) were also used to probe the surface to understand its adsorption/desorption characteristics and reducing capabilities. The results obtained from these studies together with the reaction investigations have given some important insight into the functionality of this catalyst.

Effect of H2O and SO2 on the activity of Pd/TiO2 catalysts in catalytic reduction of NO with methane in the presence of oxygen
MITOME, Junko; Karakaş, Gürkan; Bryan, Kimberly A.; Ozkan, Umit S. (1998-06-18)
Effect of H2O and SO2 on the NO reduction activity of the Pd/titania catalysts was examined in the NO+CH4+O-2 reaction. Steady-state and transient response experiments were performed using a tubular flow reactor. Isotopically labeled methane, (CH4)-C-13, was used in studying the transient behavior of the catalytic system. Reactor effluents were analyzed by using gas chromatography, mass spectrometry, and chemiluminescense techniques. Steady-state reaction experiments showed that the catalyst has a high acti...
Characterization and reactivity studies for chemical loop gasification of high sulfur lignites
Kanca, Arzu; Üner, Deniz; Department of Chemical Engineering (2013)
The objective of this study was to characterize and to determine the gasification reactivity of Tuncbilek lignites. The ultimate analysis of Tuncbilek lignite revealed that the elemental composition is 37.7% C, 3.6% H, 1.6% N, and 5.4% S, while the proximate analysis indicated 4.7 ± 0.9% moisture 27.9 ± 0.1% volatiles and 37.9 ± 0.2% ash. In this context, four different reactions during gasification namely, pyrolysis, oxidation, hydrogenation, and wet air oxidation were investigated separately. Carbon resid...
A new p-fam-silver catalyst for asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides
Eröksüz, Serap; Doğan, Özdemir; Department of Chemistry (2008)
In this study new twelve phosphorus based chiral ligands were synthesized and characterized. Then the catalytic activity of these chiral ligands was tested with Cu(II) and Ag(I) salts in asymmetric 1,3-dipolar cycloaddition reactions of azomethine ylides. This method provides the synthesis of different pyrrolidine derivatives with up to four stereogenic centers. Pyrrolidine derivatives are found in the structure of many biologically active natural compounds and drugs. Therefore the asymmetric synthesis of t...
Synthesis and characterization of poly(dihalophenylene oxide)s and its derivatives from diammine bis(trihalophenolato) Cu(II) complexes
Sonsuz, Muammer; Gökağaç Arslan, Gülsün; Department of Chemistry (2004)
In this study, synthesis and characterization of poly(dihalophenylene oxide)s were done by thermal decomposition of diamminebis(trichlorophenolato) copper(II) and diamminebis(tribromophenolato) Cu(II) complexes in solid state. 2,4,6-trichlorophenol (TCP), 2,4,6-tribromophenol (TBP) and ammonia were used as ligands in the complex syntheses. The complexes were characterized by means of X-ray diffraction, FTIR, DSC, mass spectroscopy, magnetic susceptibility and C, H, N elemental analyses. Synthesized complexe...
Investigation of the performance of colloidal LiFePO4 particles in suspension flow battery
Yıldız, Bayram; Aşkar, Yasemin; Coşkun, Elif; Maviş, Bora; Çınar, Simge (2021-06-12)
In this study, colloidal LiFePO4 particles were synthesized through solvothermal route. Effect of solvothermal method parameters on formation of colloidal LiFePO4 was investigated. Post-processing treatments were found effective to obtain non-aggregated colloidal particles. The rheological behavior of aqueous suspensions including electroactive material was examined in terms of salt, electroactive material concentration and carbon content. A three-electrode systems was used to analyze electrochemical perfor...
