Structure plays an important role in heterogeneous catalysis. It provides a framework for the arrangement and stragetic 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 catalytic guests undergo dynamic processes becoming active participants of the overall catalytic process. They are not mere static geometric forms. 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.

Photocatalysis is a reaction which is accelerated by light while a heterogeneous reaction consists of two phases ( a solid and a liquid for example). Heterogeneous Photocatalysis is a fast developing science which to date has not been fully detailed in a monograph. This title discusses the basic principles of heterogeneous photocatalysis and describes the bulk and surface properties of semiconductors. Applications of various types of photoreactions are described and the problems related to the modeling and design of photoreactors are covered.

Heterogeneous Photocatalysis: Relationships with Heterogeneous Catalysis and Perspectives highlights the differences between thermal-catalysis and photo-catalysis and indicates borderlines, in particular, the possible synergism between them. The book outlines the basic aspect of thermal- and photo-catalysis, along with the most important characterization techniques. In addition, it presents case studies of thermal-catalytic and photo-catalytic or thermal-photo-catalytic reactions and includes a comparison between the results obtained using an inorganic solid as thermal catalyst and photocatalyst for the same reaction, and in the same setup. Final sections offer information on the preparation methods of (photo)catalysts, various techniques used for their characterization, engineering and economical aspects. This book will be a valuable reference source for students and researchers involved in heterogeneous photocatalysis and catalysis, chemistry, chemical engineering, materials science, materials engineering, environment engineering, nanotechnology and green chemistry. - Provides selective methods for the preparation of microcrystalline/nanocrystalline solids or films used in catalytic and photocatalytic processes - Describes (photo)reactions that can be carried out catalytically and/or photocatalytically - Outlines the different mechanisms, yields and experimental conditions under which photocatalytic reactions can take place - Describes various (photo)reactors and set ups under which the photacatalytic reactions can be carried out - Provides an economic assessment to understand the feasibility of some photocatalytic reactions
