Book excerpt: In this book the author presents an up-to-date summary of existing information on the structure, electronic properties, chemistry and catalytic properties of transition metal oxides. The subjects covered in the book can be divided into three sections. The first (chapters 1 to 3) covers the structural, physical, magnetic, and electronic properties of transition metal oxides. Although the emphasis is on surface properties, relevant bulk properties are also discussed. The second section (chapters 4 to 7) covers surface chemical properties. It includes topics that describe the importance of surface coordinative unsaturation in adsorption, the formation of surface acidity and the role of acidity in determining surface chemical properties, the nature and reactivities of adsorbed oxygen, and the surface chemistry in the reduction of oxides. The third section (chapters 8 to 14) is on the catalytic properties. Various catalytic reactions including decomposition, hydrogenation, isomerization, metathesis, selective oxidation, and reactions involving carbon oxides are discussed. Emphasis is placed more on reaction mechanisms and the role of catalysts than on kinetics and processes. Chapters on the preparation of oxide catalysts and on photo-assisted processes are also included. Whenever appropriate, relationships between various topics are indicated. Written for surface physicists, chemists, and catalytic engineers, the book will serve as a useful source of information for investigators and as a comprehensive overview of the subject for graduate students.

Available in PDF, EPUB and Kindle. Book excerpt: Vanadium is one of the more abundant elements in the Earth’s crust and exhibits a wide range of oxidation states in its compounds making it potentially a more sustainable and more economical choice as a catalyst than the noble metals. A wide variety of reactions have been found to be catalysed by homogeneous, supported and heterogeneous vanadium complexes and the number of applications is growing fast. Bringing together the research on the catalytic uses of this element into one essential resource, including theoretical perspectives on proposed mechanisms for vanadium catalysis and an overview of its relevance in biological processes, this book is a useful reference for industrial and academic chemists alike.

Available in PDF, EPUB and Kindle. Book excerpt: The work outlined in this dissertation is dedicated to the surface chemistry of promoted metal nanoparticle catalysts for dry reforming of methane (DRM). The main part of this work focuses on the effect of promoters on platinum and nickel active catalysts and understanding how the change in surface chemistry affects the mechanism of the DRM reaction. We have identified several promoters that improve the DRM activity by tuning the surface chemistry; boron promoter with platinum catalyst and transition metal promoters with nickel catalyst. The addition of promoter sites led to the migration of coke deposits away from active sites, improved surface activation of CO2, and morphological control over the coke deposits. This work is necessary because growing concern over the effects of climate change has necessitated research into potential fossil fuel replacements. The current energy infrastructure already supports hydrocarbon fuel sources. However, researchers' current challenge is the ability to produce fuel in a carbon-neutral process using inexpensive catalytic materials. Heterogeneous catalysis is paramount to solving the energy problem, and the chemistry of catalytic surfaces must be optimized to achieve carbon-based fuel production that can replace fossil fuels long term. Noble metals and transition metals are highly active to hydrocarbon conversion. The dry reforming of methane (DRM) is a promising reaction because it converts methane and carbon dioxide into a "synthesis gas", or syngas, which can be processed to produce fuels and other value-added chemicals. When in the form of a nanoparticle supported on metal oxide, the active surface area of the metal is maximized, and less metal is required for catalysis. However, nanoparticle catalysts are readily deactivated by coking (carbon deposits) and sintering (nanoparticle agglomeration). Noble metals are highly active to DRM due to their high selectivity and resistance to deactivation, but they are typically too costly for practical use. Nickel is a promising DRM catalyst because of its low cost and high activity but is more susceptible to deactivation, therefore nickel is often paired with a second "promoter" metal to optimize the material and prevent deactivation. The development of active, stable bimetallic catalysts requires a detailed understanding of the chemistry at the surface during the reaction. In this work, we have identified the role of promoter sites using surface characterization techniques which provide better understanding of the catalytic mechanism.

Available in PDF, EPUB and Kindle. Book excerpt: As in the study of transition metal complexes in solution, molecular spectroscopic methods - principally the infrared, ultraviolet/visible and electron spin resonance spectroscopies - have played key roles in establishing the concepts of coordination chemistry occurring at the surfaces of solids. This book describes the development of the principals of coordination chemistry of oxide surfaces using analyses of data obtained by these methods. The nature, properties, concentration of the surface adsorption centers and their influence on the character of interaction with different molecules are investigated. The book commences with an account of the basic theoretical principles and experimental techniques of the various spectroscopy methods, with special attention devoted to in situ measurements where the oxide or catalyst sample is in contact with the adsorbate or the reactant. A detailed account is presented of the methods for characterizing the oxidation state and degree of coordination of surface cations and oxygen anions by the adsorption of probe molecules. The complexation of many inorganic, organometallic and organic molecules with different oxide systems is critically examined, and a classification of formed surface compounds, based on the interaction with definite type of adsorption centers, is given. Possible mechanisms of numerous catalytic reactions, including the transformation of organic molecules over acidic catalysts via the carboionic mechanism, are discussed using the spectroscopic identifications of reaction intermediates. A comprehensive analysis of the literature on the interpretation of the spectra of surface compounds on oxides is presented. This highly illustrated and extensively referenced volume is intended for specialists working in the fields of surface physical chemistry, surface and materials sciences, and adsorption phenomena and is essential reading for those involved in the heterogeneous catalysis by transition metal-oxides.

This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vanadium oxides are key industrial catalysts in the oxidation and functionalization of various chemical compounds, and studies of gas-phase vanadium oxide clusters provide an avenue to explore the reactive sites implicated in surface catalysis. An extensive amount of experimental data has been reported on the gas-phase fragmentation of vanadium oxide cluster ions and their reactions with environmentally-relevant halocarbons. Our computational studies aim at further understanding the structure and properties of vanadium oxide clusters, as well as their reactivity towards fluorocarbons. Accordingly, we report a systematic density-functional theory (DFT) study of the structural and electronic properties of V x O y + and V x O y clusters, and investigate their reactions with CH 2 F 2 and CH 3 CF 3 by DFT calculations. Our results suggest that both B3LYP/TZVP and PLAP4/DZVP+aux. are appropriate model chemistries to investigate vanadium oxide clusters, but the latter is less computationally intensive, and thus more suitable for large clusters. Stable ground-state and low-lying excited-state structures and their electronic properties are obtained for both V x O y + and V x O y (x = 1-4, y = 1-10) clusters with the PLAP4/DZVP+aux. model chemistry. The molecular structures and electronic properties of large polyvanadium oxide clusters are systematically investigated and reported for the first time. The reaction of V 2 O 4 + with fluorocarbons was investigated with the B3LYP/TZVP model chemistry. Oxygen transfer and stepwise HF abstraction from the fluorocarbon are observed in the reactions of V 2 O 4 + with CH 2 F 2 and CH 3 CF 3, respectively. These reaction mechanisms help explain why larger clusters such as V 4 O 8 + were observed to be chemically inert towards CH 2 F 2, while the reactivity of V x O y + cluster ions towards CH 3 CF 3 was not found to depend on cluster size experimentally.
