Chemical industries are based on catalytic processes as both bulk and fine chemicals are often produced with heterogeneous catalysts. They are classified as acid-base nd redox catalysts. Transition metal ions dispersed on a high-surface area inorganic solid belong to the last category. A full characterization of these transition metal ions on surfaces requires knowledge of their oxidation state, coordination environment and dispersion. This information can be obtained with 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. Emphasis is placed on the basic principles and the strengths and weaknesses of the spectroscopic tools in order to give the reader a solid background for judging literature results and for planning and conducting his/her own experiments. Each chapter closes with selected 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.
