Preface

Abstract

The complexity and inhomogenicity of catalytic sites of metals and metal oxides make it difficult to interpret the mechanism of catalytic reactions on solid surfaces. The book, “Advances in catalysis and related subjects, volume 22,” reviews the approaches made in describing catalytic sites and chemisorbed species. By combining infrared (IR) spectroscopy with hydrogen isotope techniques and by applying kinetic and stereochemical considerations, it is possible to determine the intermediate surface species in the hydrogenation and isomerization of simple olefins over zinc oxide. The book describes the effect of metal particle size on the properties of a metal on carrier catalyst. They have related the adsorptive and catalytic properties of metal crystals to crystal size and to the structure of the crystal surface. The application of electron spin resonance (ESR) to the determination of the state of transition metal ions in catalytic reactions is discussed in the book.
