The theoretical basis of chemisorption and catalysis by metals and alloys, and their use in a range of model and industrially significant catalysed processes are described in this book.
Model, as well as industrially used reactions catalyzed by alloys are reviewed, among them the Fischer-Tropsch synthesis, reactions of alkanes ('reforming'-reactions), oxidations, hydro-/dehydrogenation, decomposition of methanoic acid, deuterium exchange reactions (H2, hydrocarbons) and to a lesser extent some others. This review on catalytic reactions, with results from the available information, is introduced in two chapters which summarize the definition, the physical meaning and the role of such factors as ligand (electronic structure), ensemble size (geometrical) and ensemble composition effects. The assessment of the roles of these individual factors requires the knowledge of several physical techniques and a proper evaluation of the results obtained by them. An introduction to this field of physics forms the content of the introductory chapters of this book.
A long period (1968-1994) of intensive research into catalysis by alloys has just been concluded so that reliable conclusions can be drawn concerning the roles of ligand, geometric and compositional effects. Particular attention is paid to the connection between chemisorption and catalytic phenomena, and their dependence on the structure of the surface as revealed by current techniques of solid-state physics is highlighted.Scientists in related fields, such as electrochemistry, solid state chemistry, materials science, corrosion, tribology and other fields of applied surface science, organic synthesis and general inorganic chemistry should find the information contained in this book of interest in their work.

...the chapters in this book dealing with various aspects of catalyst structure (Chapters 1-7) are informative, comprehensive, and well done, particularly in view of the size of the literature.
Journal of Catalysis
The figures have legends of several lines in most cases which makes them easy to understand... The book is a good guide for everybody who possesses more than rudimentary familiarity with the subject and wants to start in this field; at the same time, it offers profitable assistance for more advanced specialists who might need a good review of the whole field and, what may be even more important, of related areas such as solid-state physics. It belongs to the shelf of every postgraduate student and also scientist practising in the field of metal and alloy catalysis, especially, if the reactions selected involve hydrocarbons as feed or products. I congratulate both distinguished authors for their present excellent work.
