Book Synopsis Catalysis By Gold by : Geoffrey C Bond
Download or read book Catalysis By Gold written by Geoffrey C Bond and published by World Scientific. This book was released on 2006-08-15 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gold has traditionally been regarded as inactive as a catalytic metal. However, the advent of nanoparticulate gold on high surface area oxide supports has demonstrated its high catalytic activity in many chemical reactions. Gold is active as a heterogeneous catalyst in both gas and liquid phases, and complexes catalyse reactions homogeneously in solution. Many of the reactions being studied will lead to new application areas for catalysis by gold in pollution control, chemical processing, sensors and fuel cell technology. This book describes the properties of gold, the methods for preparing gold catalysts and ways to characterise and use them effectively in reactions. The reaction mechanisms and reasons for the high activities are discussed and the applications for gold catalysis considered./a
Book Synopsis Kinetics and Dynamics of Oxidation Reactions Involving an Adsorbed CO Species on Bulk and Supported Platinum and Copper-oxide by :
Download or read book Kinetics and Dynamics of Oxidation Reactions Involving an Adsorbed CO Species on Bulk and Supported Platinum and Copper-oxide written by and published by . This book was released on 1991 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposed research is an integrated experimental and modeling study of oxidation reactions involving CO as a key player -- be it a reactant, adsorbed intermediate, and/or partial oxidation product -- in the catalytic sequence and chemistry. The reaction systems of interest in the project include CO, formaldehyde, and methanol oxidation by O2 and CO oxidation by NO, on both Pt and copper oxide catalysts. These reactions are of importance in automobile exhaust catalysis. There is a paucity of rate data in the literature for these important environmental control reactions. The goal of this research is to better understand the catalytic chemistry and kinetics of oxidations reactions involving CO as an adsorbed intermediate. Successfully meeting this goal requires an integration of basic kinetic measurements, in situ catalyst surface monitoring, kinetic modeling, and nonlinear mathematical tools.

Book Synopsis Effect of Phase Composition Between Gamma and Chi Alumina Supports on Oxygenative Reaction by : Chatchai Meephoka
Download or read book Effect of Phase Composition Between Gamma and Chi Alumina Supports on Oxygenative Reaction written by Chatchai Meephoka and published by . This book was released on 2008 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, the mixed-phase alumina supports were prepared by solvothermal method of a mixed solution of toluene and butan-1-ol and used as supports for Pt/Al2O3 and Ag/Al2O3 catalysts. Characterization results show that the BET surface areas of the gamma and chi alumina are similar but their acidities are different. The effect of phase composition on the catalysts properties was studied in various reactions, i.e., SCR of NO by propene under lean-burn condition, CO oxidation and selective CO oxidation in excess H2. For SCR of NO by propene under lean-burn codition, Ag/Al2O3 catalysts were investigated. The results show that 10% chi alumina catalysts yield the highest activity because of a large amount of Ag metal, which is the major active site for this reaction. For CO oxidation, Pt/Al2O3 catalysts were studied. The results show that the mixed-phase catalysts are more active than both pure gamma and chi alumina except for 10% chi alumina. The high activity is obtained due to high dispersion of platinum oxide on the support. Finally, for CO oxidation under excess H2, the Pt supported on chi alumina is more active than that on gamma alumina because of the weak adsorption of H2 and CO on chi alumina.

Available in PDF, EPUB and Kindle. Book excerpt: Objectives were to formulate kinetic models/mechanistic sequences, and to develop bifunctional catalysts for selective oxidation of hdyrocarbons. Efforts are reported this year on 3 items: development of Fourier transform infrared emission spectroscopy to monitor near infrared (ir) under reaction conditions (ethylene oxidation on V2O5); kinetics study of methanol oxidation on supported Pt catalysts (methanol-rich feed the CO2 yield exhibits a maximum at an intermediate temperature); and comparative kinetics study of CO oxidation on Pt, Pd, and Rh. The ir spectra of V2O5 show a correlation between the ir features and the degree of surface oxidation. 4 figs. (DLC).

Book Synopsis Equilibria and Dynamics of Gas Adsorption on Heterogeneous Solid Surfaces by : W.A. Steele
Download or read book Equilibria and Dynamics of Gas Adsorption on Heterogeneous Solid Surfaces written by W.A. Steele and published by Elsevier. This book was released on 1996-12-17 with total page 909 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fact that the surfaces of real solids are geometrically distorted and chemically non-uniform has long been realized by the scientists investigating various phenomena occurring on solid surfaces. Even in the case when diffraction experiments show a well-organized bulk solid structure, the surface atoms or molecules will usually exhibit a much smaller degree of surface organization. In addition to the results obtained from electron diffraction, this can be seen in the impressive images obtained from STM and AFM microscopies. This geometric and chemical disorder is the source of the energetic heterogeneity for molecules adsorbing on real solid surfaces. Hundreds of papers have been published showing that this heterogeneity is a major factor in determining the behaviour of real adsorption systems. Studies of adsorption on energetically heterogeneous surfaces have proceeded along three somewhat separate paths, with only minor coupling of ideas. One was the study of adsorption equilibria on heterogeneous solid surfaces. The second path was the study of time evolution of adsorption processes such as surface diffusion or adsorption-desorption kinetics on heterogeneous surfaces, and the third was the study of adsorption in porous solids, or more generally, adsorption in systems with limited dimensions. The present monograph is a first attempt to provide a synthesis of the ways that surface geometric and energetic heterogeneities affect both the equilibria and the time evolution of adsorption on real solids. The book contains 17 chapters written by a team of internationally recognized specialists, some of whom have already published books on adsorption.

Book Synopsis Plasma Catalysis by : Annemie Bogaerts
Download or read book Plasma Catalysis written by Annemie Bogaerts and published by MDPI. This book was released on 2019-04-02 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.
