PREFACE
Structure plays an important role in heterogeneous catalysis. It provides a framework for
the arrangement and strategic placement of key catalytic elements, hosting them in a
prescribed manner so that their respective electronic properties can exhibit their desired
catalytic functions and mutual interactions. Under reaction conditions these framework
structures and their key catalytic guests undergo dynamic processes becoming active
participants of the overall catalytic process. They are not mere static geometric forms. The
framework provides the necessary crystal structure stabilization and hence acts as a
template. Non-stoichiometry and vacancy rearrangements of the solids are important
factors contributing to these dynamic processes of catalytic reactions. The dynamics of
catalytic structures are particularly vivid in selective oxidation catalysis where the lattice of
a given catalytic solid partakes as a whole, not only its surface, in the redox processes of the
reaction. The catalyst becomes actually a participating reagent. By proper choice of key
catalytic elements and their host structures preferred catalytic pathways can be selected
over less desired ones. However, not only in selective redox catalysis does structure play
an important role, its importance is also well documented, among others, in shape selective
zeolite catalysis, enantioselective hydrogenation and hydrodesulfurization.
The contributions presented in this book address the dynamic character of the solid state
under catalytic reaction conditions. By relating structure to activity and selectivity in
heterogeneous catalysis our understanding of such correlations has been significantly
enhanced through the use of sophisticated spectroscopic means, surface science and
modeling. Nonetheless, the ultimate test of the correlations remains the actual catalytic
reaction.
The individual contributors who made this update of structure activity and selectivity
correlations in heterogeneous catalysis possible are herewith sincerely thanked.
