Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to review the current, state-of-the-art application of isotopic methods to the field of heterogeneous catalysis. Isotopic studies are arguably the ultimate technique in in situ methods for heterogeneous catalysis. In this review volume, chapters have been contributed by experts in the field and the coverage includes both the application of specific isotopes — Deuterium, Tritium, Carbon-14, Sulfur-35 and Oxygen-18 - as well as isotopic techniques — determination of surface mobility, steady state transient isotope kinetic analysis, and positron emission profiling.

Available in PDF, EPUB and Kindle. Book excerpt: Isotopic Assessment of Heterogeneous Catalysis deals with the use of isotopic tracing to study the reaction mechanisms involved in heterogeneous catalysis. It presents special methods for using isotopic and radioactive atomic species for obtaining meaningful kinetic data that can be quantitatively used in mechanistic modeling. It also considers a number of industrial reactions under steady-state reaction conditions in which superposed tracer transfer is also at steady state. This book is comprised of eight chapters and begins with an introduction to heterogeneous catalysis and an approach to reaction modeling, as well as the experimental reactors for obtaining the type of measurements and data needed in transient modeling. The application of isotopes in studies of heterogeneous catalysis is also discussed. Subsequent chapters focus on the choice of intermediates and reaction steps in tracer experiments; the number of overall stoichiometric chemical reactions that can occur in order to generate product molecules from reactants; superposition modeling of mechanisms; and steady-state tracing. Transient tracing and the development of rate equations are also described. This monograph is intended primarily for students and teachers of such subjects as physical chemistry, as well as research scientists and technologists.

Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of catalytic reactions exists at various levels which are mainly defined from detailed knowledge of reaction mechanism. When viewed in terms of the stoi chiometric reaction equation, most catalytic reactions are complex processes which occur via a sequence of elementary (i. e. irreducible) steps, and the elucidation ofthese elementary steps and the identification of a rate determining step (if one exists) constitutes the traditional approach to the problem of mechanism. The term "traditional" is not used here in a pejorative sense since mechanistic knowledge of this sort makes an important contribution to catalyst design, improvement, and optimization. This is the field which is discussed by Professor R. L. Burwell in Chapter 1 where the very wide range of useful approaches and techniques is made apparent, even when one is restricted to quasi-steady state conditions. Techniques which depend on observations under non steady state conditions (i. e. relaxation methods) have also been used in mechanistic studies, increasingly so in recent years. This topic is discussed in detail by Professor K. Tamaru in Chapter 2. At a deeper level of understanding, one may seek to enquire how an elementary reaction proceeds in terms of movement in a multicoordinate space where the variables define atomic positions and energy. This is a problem of great complexity even in relatively simple cases. Nevertheless, despite the problems some progress is being made, and this and allied topics are discussed in Chapter 3 by Professor G. L. Haller and Dr. G. W. Coulston.

This book was released on 2012-12-06 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprises the proceedings of a NATO sponsored Advanced Research Workshop held from 1st November to 6th November 1992 in the delightful Chateau de Florans, Bedoin, Vaucluse, France and entitled 'Elementary Reaction Steps in Heterogeneous Catalysis. ' The organisers are grateful to the Science Committee of NATO for their support of this meeting. This is believed to be the first wide ranging NATO ARW in the field of heterogeneous catalysis for 20 years, following a previous venture organised in Sardinia by Basolo and Burwell, of Northwestern University, Illinois, USA [1]. This volume collects the lecture presentations and reports on the lively Panel discussions. The idea for the meeting evolved from a series of International Symposia on Quantum Chemistry and Mechanism in Heterogeneous Catalysis. The first of these was held in Lyon, France in 1986, the second in Krakow, Poland in 1988 and the third in Berkeley, California in 1990. The organising committee of the present meeting was Bernard Bigot, France, Tony Farragher, Netherlands, Richard Joyner, UK, Mme. Danielle Olivier, France, and Rutger van Santen, Netherlands, (Chairman). We wish to thank all members of the committee but in particular Bernard Bigot, who undertook the very extensive work involved in the local organisation with consummate skill and made our stay in Provence a great pleasure. Bernard Bigot's secretary, Mme. Marie-Noelle Coscat and Richard Joyner's secretary, Mrs. Pat Gibbs, also deserve our considerable thanks. There were fifty-four participants from eleven countries.

Available in PDF, EPUB and Kindle. Book excerpt: Mixed oxides are the most widely used catalyst materials for industrial catalytic processes. The principal objective of this book is to describe systematically the mixed oxide catalysts, from their fundamentals through their practical applications. After describing concisely general items concerning mixed oxide and mixed oxide catalysts, two important mixed oxide catalyst materials, namely, heteropolyacids and perovskites, are taken as typical examples and discussed in detail. These two materials have several advantages: 1. They are, respectively, typical examples of salts of oxoacids and double oxide, that is, the two main categories of mixed oxides in solid state chemistry. 2. Both exhibit excellent catalytic performance in nearly crystalline state and are used in several industrial applications. 3. They have studied for many years. In addition, metal oxides functioning as a catalyst support (carrier) are included. Although the supports are very important in practical applications, and tremendous progress has been made in the past decades, few systematic reviews exist. It is notable that heteropolyacids and perovskite exhibit unique performance when used as a support. Fundamental catalytic science and technology and solid state chemistry necessary is presented for the proper understanding of mixed oxide catalysts as well as for R&D. For the latter, the concept of design of practical catalysts is very important. This is considered throughout the book. Systematically describes design principles of mixed oxide catalysts Shows how catalysis and solid-state chemistry of metal oxides are inter-related Covers all useful basic concepts of mixed oxide catalysis

Download or read book In situ Spectroscopy in Heterogeneous Catalysis written by James F. Haw and published by Wiley-VCH Verlag GmbH. This book was released on 2002 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Not using in-situ methods to examine catalytic processes is like studying a life with access only to the prenatal and postmortem states." This quote from the world renowned specialist in the field of in situ methods, Gabor A. Somorjai, clearly emphasizes the importance of these techniques in understanding heterogeneous catalysis - a type of chemical reaction used nowadays for most chemically produced supplies and fuels. Yet the fundamental mechanisms are often still not completely understood. Many of the leading scientists in the field have contributed to this book which provides an overview of the most varied spectroscopic and related methods for studying catalytic structures and their functions during a chemical reaction. While primarily written for users of these methods, this is also a valuable aid to interpreting the phenomena observed. Indispensable for everyone working in the field.
