This volume provides the reader with the most up-to-date and relevant knowledge on the
reactivity of metals located in zeolite materials either in framework or extra-framework
positions and the way it is connected with the nature of the chemical environment provided by
the host. Since the first report of the isomorphous substitution of titanium in the framework
of zeolites giving rise to materials with unusual catalytic properties the incorporation of
many other metals have been investigated with the aim for developing catalysts with improved
performance in different reactions. The continuous expansion of the field both in the variety
of metals and zeolite structures has been accompanied by an increasing focus on the
relationship between the reactivity of metal centers and their unique chemical environment.The
concepts covered in this volume are of interest to people working in the field of inorganic and
physical chemistry catalysis and chemical engineering butalso for those more interested in
theoretical approaches to chemical reactivity. In particular the volume is useful to
postgraduate students conducting research in the design synthesis and catalytic performance of
metal-containing zeolites in both academic and application contexts.
