This book deals with adsorption and catalysis on the surface of transition elements and their compounds, many of which are in teresting because of their particular electronic structure. The authors have worked through a vast body of experimental evi dence on the structure and properties of surfaces of transition metals and relevant oxides. Consideration is given mostly to simple (as opposed to mixed) oxides of transition elements, to common metals and to the adsorption of simple gases. A great deal of attention is paid to the nature of active surface sites responsible for chemisorption and catalytic transformations. The description relies mainly on the simplified ligand-field theory, which, however, proves quite satisfactory for predicting the adsorptive and catalytic activity of species. In many cases simple systems were explored with the aid of novel techniques, and it is only for such systems that the mechanism of the ele mentary act of adsorption and catalysis can be given adequate treatment. The present monograph has emerged from our earlier work in Russian, which appeared in the Khimiya Publishing House (Mos cow) in 1981. This English edition has, however, been revised completely to broaden its scope and to include more recent a chievements. For fruitful discussions the authors are grateful to A.A.

The Symposium was held to honour the memory of the late Dr. A.J. Tench who made numerous important contributions to our knowledge of the structure, reactivity and adsorption properties of oxide surfaces. This volume contains an up-to-date picture of adsorption and catalysis on oxide surfaces, not in the form of a comprehensive review but in its living aspects of work in progress. It describes detailed studies on the determination of the coordination surface ions, particularly oxide ions, by photoluminescence and reflectance spectroscopy, on the identification of adsorbed species by magnetic optical or surface techniques and on catalysis, with emphasis on new concepts such as catalysis involving excited states or structure sensitive reactions.Professionals working in the industrial and academic laboratories will find the book particularly useful as it provides a state-of-the-art account of our understanding of the structure and adsorption characteristics of oxide surfaces. Contained in the book are first class research papers by leading exponents in this field. A very important issue is that the book highlights for the first time the importance of excited states and structure sensitivity in determining the behaviour of oxide surfaces.

There has been a lack of authoritative, current information on the structure, investigation and preparation of inorganic sorbents, their numerous applications as well as the adsorption from gaseous and liquid phases on new and chemically modified inorganic solids. This volume deals with the above-mentioned themes and presents 34 up-to-date comprehensive and critical reviews written by well-recognized authorities. The sorbents discussed are primarily mineral ones. Each contribution treats a problem critically by showing its development, presenting documentation on the state-of-the-art and identifying subjects for further research. The book will be of interest to researchers in academic institutes and industrial laboratories engaged in the fields of surface chemistry, inorganic chemistry, adsorption, ion-exchange, catalysis, chromatography and spectroscopy of the surface phenomena, as well as to students attending graduate and postgraduate courses.

Heterogeneous catalysis provides the backbone of the world's chemical and oil industries. The innate complexity of practical catalytic systems suggests that useful progress should be achievable by investigating key aspects of catalysis by experimental studies on idealised model systems. Thin films and supported clusters are two promising types of model system that can be used for this purpose, since they mimic important aspects of the properties of practical dispersed catalysts. Similarly, appropriate theoretical studies of chemisorption and surface reaction clusters or extended slab systems can provide valuable information on the factors that underlie bonding and catalytic activity. This volume describes such experimental and theoretical approaches to the surface chemistry and catalytic behaviour of metals, metal oxides and metal/metal oxide systems. An introduction to the principles and main themes of heterogeneous catalysis is followed by detailed accounts of the application of modern experimental and theoretical techniques to fundamental problems. The application of advanced experimental methods is complemented by a full description of theoretical procedures, including Hartree-Fock, density functional and similar techniques. The relative merits of the various approaches are considered and directions for future progress are indicated.

"Spillover and Mobility of Species and Solid Surfaces" collects the papers which were presented at the Fifth International Conference Spillover, either as oral or poster contributions, as well as the summaries of the invited lectures. This congress and its publication in the Studies on Surface Science and Catalysis series follow the tradition of previous conferences on spillover, initiated in Lyon, 1983, and continued in Leipzig, 1989, Kyoto 1993 and Dalian, 1997. For the fifth conference, held in S.L. el Escorial (Madrid), the organising committee has attempted to compile representative contributions which illustrate the advances in understanding the spillover phenomenon since 1997. Spillover is a process taking place during the interface of gas reactant molecules (mainly hydrogen and oxygen) on solid surfaces. However, different contributions to the more general area of the chemistry at surfaces, related with the mobility and migration of species, diffusion through membranes, fuel cell catalysts, etc., have also been included. In fact the title of the present volume summarizes this attempt to extend the conference topics towards dynamics at surfaces.Among the 70 contributions received, the 56 accepted papers were selected on the basis of the reports of at least two international reviewers, according to standards comparable to those applied for other specialised journals. These papers are from 21 different countries.

Surface science emerged in the 1960s with the development of reliable ultrahigh vacuum apparatus, providing exact structures of surfaces of metal single crystals, information about their compositions, and relationships between surface structure and composition and catalytic reaction rates. Catalysis, the acceleration of a chemical reaction by a catalyst (substance), provided much of the driving force for the early development of surface science. As surface science continues its rapid development, this book illustrates how it is still driven by the challenges of catalysis and how both theory and scanning tunneling microscopy have forcefully emerged as essential tools. It is also evident how surface science continues to serve as the foundation of catalytic science. This is a compendium written by leading surface scientists presenting an incisive assessment of up-to-date theoretical and experimental results constituting the foundation of fundamental understanding of surface catalysis.

The first chapter of the book summarizes classical approaches, introduces the concept of ionicity, and describes the mixed iono-covalent character of the oxygen cation bond in bulk materials. The next three chapters focus on the characteristics of the atomic structure (relaxation, rumpling and reconstruction effects), the electronic structure (band width, gap width, etc.) and the excitations of clean surfaces.
