Oxide semiconductors, including titanium dioxide (TiO2), are increasingly being considered as replacements for silicon in the development of the next generation of solar cells. Oxide Semiconductors for Solar Energy Conversion: Titanium Dioxide presents the basic properties of binary metal oxide semiconductors and the performance-related properties of TiO2 as they relate to solar energy. The book provides a general background on oxide semiconductors based on binary oxides and their solid solutions, including electronic and ionic conductors. It covers several aspects of solid-state electrochemistry of oxides, such as defect chemistry, and defect-related properties, such as electrical properties, diffusion, segregation, and reactivity. The author also takes a pioneering approach in considering bulk versus surface semiconducting properties, showing how they are different due to the effect of segregation. One of the first on semiconducting, photocatalytic, and photoelectrochemical properties of TiO2 and its solid solutions with donor- and acceptor-type ions, the book discusses defect chemistry of TiO2 in terms of defect equilibria and defect-related properties, including electrical properties, self and chemical diffusion, surface properties, segregation, and reactivity and photoreactivity with oxygen, water, and microbial agents. The text also illustrates the use of TiO2 as an emerging material for solar energy conversion systems, including the generation of hydrogen fuel by photoelectrochemical water splitting, the photocatalytic purification of water, and the generation of photovoltaic electricity. In addition, it presents defect disorder diagrams for the formation of TiO2-based semiconductors with controlled properties. Encompassing the areas of solid-state science, surface chemistry, and photocatalysis, this book reflects the increasing awareness of the importance of structural imperfections, such as point defects, in understanding the properties of metal oxides, specifically TiO2-based semiconductors.

This volume is focused on the materials and devices for solar-to-chemical energy conversion. The introductory paper, by Alim and Bak, considers the basic concepts of the light-induced water oxidation by oxide semiconductors. This paper is concentrated on the photoreactivity of metal oxides, such as TiO2, with water and the related charge transfer during partial and total oxidation. The second paper of Yang et al provides an overview on the performance of TiO2 as photoanode in photoelectrochemical water oxidation. The paper of Nasir et al considers application of BiVO4 as photoelectrode for the generation of solar hydrogen fuel using water as the raw material. The work of Pastuovic et al is a treatise on the application of accelerator-based nuclear techniques in the characterisation of oxide semiconductors for solar energy conversion. This volume is addressed to those interested in the progress of research in oxide materials for solar energy conversion.

The objective of the present volume is to develop the theory and practice of nonmetal electrochemistry from first principles, emphasizing energy level models, in particular the fluctuating energy level model of Marcus and Gerischer. A single volume emphasizing these models. and the in terpretation of experiments based on these models, has not been available. Yet this area of electrochemical technology, where the use of such models is required, has developed a great deal of interest. This is not only because of the interest in photoelectrochemical solar cells, but also because of the importance of the concepts in corrosion, sensors, coated metal electrodes, and, indeed, to the general theory of electrode reactions. This book is an attempt to fill the void-to develop in a single volume the basic description of electrode reactions on nonmetallic electrodes and oxide-covered metal electrodes. The development of the fluctuating energy level model to describe electrode reactions on nonmetals (as described in Chapters I through 3) has permitted a significant forward step in the understanding of such re actions. The power of the model is illustrated by the simple methods available to determine the energy levels of interest-the conduction and valence bands of the nonmetals (Chapter 5), and their relation to the energy levels of oxidizing or reducing agents in solution. In Chapter 6, we illustrate the ability of the simple models. based on these parameters, to describe successfully electrode reactions at an inert electrode.

The aim of this book is to fill the gap in the scientific literature by providing a comprehensive overview on the surface and near-surface chemistry of oxide materials. Oxide materials are important in a wide range of technological applications, which has resulted in a large bibliography devoted to their properties. The range of practical applications of metal oxides has recently been significantly extended by the discovery of high T c oxide superconductors. Surface chemistry overlaps with several other disciplines and involves some specialized physical methods, therefore renown scientists active in various fields were invited to contribute to the book. The present volume involves surface characterization of metal oxides as well as surface and near-surface phenomena including gas-solid, solid-solid and liquid-solid interphases. Both basic problems and applied aspects are covered. The theoretical background of ideal and real surfaces as well as surface phenomena such as adsorption, segregation, interphase interactions, equilibration, etc., are dealt with. A comprehensive description is given of the most useful experimental techniques for studying surface and near-surface (grain boundary) chemistry of ceramic materials, oxide catalysts, semiconductors and other oxide materials of practical importance. The range of practical applications of metal oxides has recently been significantly extended by the discovery of high T c oxide superconductors. A special chapter is devoted to High T c oxide superconductors, which provides an up-to-date and thorough review of this currently ''hot topic'' which will be of great interest to a wide section of the scientific community.
