The present volume concentrates on catalyst surfaces. The interaction of adsorbed molecules, mostly on heterogenous catalysts, although some reference to model catalysts is also made, is discussed here. Vibrational (infrared and electron energy loss spectroscopies, magnetic resonances (nuclear and electron spin) and thermal desorption methods have been included in this latter category. The reader will find also a comparison of these well established methods with their recent developments which make them much more attractive. Therefore, researchers working in the catalysis field will find much to interest them in this book.

Helps researchers develop new catalysts for sustainable fueland chemical production Reviewing the latest developments in the field, this bookexplores the in-situ characterization of heterogeneous catalysts,enabling readers to take full advantage of the sophisticatedtechniques used to study heterogeneous catalysts and reactionmechanisms. In using these techniques, readers can learn to improvethe selectivity and the performance of catalysts and how to preparecatalysts as efficiently as possible, with minimum waste. In-situ Characterization of Heterogeneous Catalysts featurescontributions from leading experts in the field of catalysis. Itbegins with an introduction to the fundamentals and thencovers: Characterization of electronic and structural properties ofcatalysts using X-ray absorption fine structure spectroscopy Techniques for structural characterization based on X-raydiffraction, neutron scattering, and pair distribution functionanalysis Microscopy and morphological studies Techniques for studying the interaction of adsorbates withcatalyst surfaces, including infrared spectroscopy, Ramanspectroscopy, EPR, and moderate pressure XPS Integration of techniques that provide information on thestructural properties of catalysts with techniques that facilitatethe study of surface reactions Throughout the book, detailed examples illustrate how techniquesfor studying catalysts and reaction mechanisms can be applied tosolve a broad range of problems in heterogeneous catalysis.Detailed figures help readers better understand how and why thetechniques discussed in the book work. At the end of each chapter,an extensive set of references leads to the primary literature inthe field. By explaining step by step modern techniques for the in-situcharacterization of heterogeneous catalysts, this book enableschemical scientists and engineers to better understand catalystbehavior and design new catalysts for green, sustainable fuel andchemical production.

Superbly organized and of great pedagogic value, 'Spectroscopy in Catalysis' describes the most important modern analytical techniques used to investigate catalytic surfaces. These include electron, ion, and vibrational spectroscopy, mass spectrometry, temperature-programmed techniques, diffraction, and microscopy. With the focus on practical use, rather than theory, each chapter presents current applications to illustrate the type of information that the technique provides and evaluates its possibilities and limitations, allowing selection of the best catalyst and the correct technique to solve a given problem. This third edition includes significant new developments and case studies, with all the chapters updated by way of recent examples and relevant new literature. For students and for everyone who wants a digestible introduction to catalyst characterization. From reviews of the previous editions: 'This is a truly valuable book ... very useful for industrial practitioners who need to be aware of the type of information that can be obtained from modern surface spectroscopies .... The book has a superb pedagogic value...' Journal of Catalysis '... this is an excellent text on spectroscopies in catalysis and I highly recommend it for ... introductory courses on heterogeneous catalysis or as a general introductory monograph.' Journal of the American Chemical Society

Heterogeneous catalysis has undergone a revolutionary change in the past two decades due to the development of sophisticated characterization methods that provide fundamental information about the catalyst bulk structures, surfaces, and their properties. For the first time, these characterization methods have allowed researchers to "see" the surfaces of catalytic materials, their bulk structures (crystalline as well as amorphous phases), the influence of the process conditions on the catalytic material, as well as the effect of different synthesis methods. This new information has tremendously advanced our understanding of catalytic materials and their properties. These characterization methods have become our "eyes" and are indispensible in the development of new catalytic materials. It is hard to conceive of a modern heterogeneous catalysis activity, be it research or manufacturing, without the aid of these new characterization techniques.

Reactive, but not a reactant. Heterogeneous catalysts play an unseen role in many of today's processes and products. With the increasing emphasis on sustainability in both products and processes, this handbook is the first to combine the hot topics of heterogeneous catalysis and clean technology. It focuses on the development of heterogeneous catalysts for use in clean chemical synthesis, dealing with how modern spectroscopic techniques can aid the design of catalysts for use in liquid phase reactions, their application in industrially important chemistries - including selective oxidation, hydrogenation, solid acid- and base-catalyzed processes - as well as the role of process intensification and use of renewable resources in improving the sustainability of chemical processes. With its emphasis on applications, this book is of high interest to those working in the industry.

Chemical industries are based on catalytic processes as both bulk and fine chemicals are often produced with heterogeneous catalysts. Transition metal ions dispersed on high-surface area inorganic solids are very important catalysts and a full characterization of these materials requires a profound knowledge of the oxidation state, coordination environment and dispersion of the metal ions on the catalyst surface. Such information can only be obtained by using a combination of complementary spectroscopic techniques. 'Spectroscopy of Transition metal ions on Surfaces' serves as an introduction to some of the most important spectroscopic techniques nowadays used for studying the chemistry and catalytic properties of transition metal ions on surfaces. The basic principles and the strengths and weaknesses of continuous wave electron spin resonance, pulsed electron spin resonance, solid state nuclear magnetic resonance, infrared spectroscopy, Raman spectroscopy, diffuse reflectance spectroscopy and X-ray photoelectron spectroscopy are critically reviewed by internationally recognized experts. This gives the reader a solid background for judging literature results and for planning and conducting his/her own experiments. Each chapter closes with several relevant examples mainly from the recent literature. In addition, the use of in situ techniques and chemometrical techniques has been included because of its growing importance in catalyst characterization. As a consequence, the book has been written as a text not only for graduate students, but also for anyone else who is new in the field and wants a recent update. The following scientists have contributed to this textbook: Br.
