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.

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.

Spectroscopy in Heterogeneous Catalysis deals with the applications of spectroscopy in heterogeneous catalysis. The concepts and capabilities of a particular technique, experimental procedures, and examples of all proven or potentially important applications are discussed. The use of spectroscopic measurements in guiding empirical approaches to applied problems and to fundamental studies of the chemical identity of catalytic surfaces is also described. This book is comprised of eight chapters and begins with a discussion on the scope of spectroscopy in catalysis and applications of spectroscopy to zeolite catalysts. The following chapters focus on infrared spectroscopy, with emphasis on the theory and interpretation of infrared spectra; Raman spectroscopy and the theory of the Raman effect; diffuse reflectance and photoacoustic spectroscopies; and Mössbauer spectroscopy. Electron spin resonance spectroscopy and nuclear magnetic resonance spectroscopy are also considered. The final chapter is devoted to X-ray photoelectron spectroscopy (XPS) and its application to core electrons, along with the experimental equipment and procedures used. The applications of XPS to studies of surface behavior and catalyst composition and chemistry are outlined. This monograph will be a useful resource for physicists, researchers, and potential researchers in heterogeneous catalysis.
