Oxide Semiconductors for Solar Energy Conversion
Wydawnictwo: CRC Press Inc.
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. The present book provides a comprehensive survey of defect chemistry and defect-related properties of oxides, including electronic structure, charge transport, diffusion, and segregation. ! [This] book is probably the only survey on semiconducting and photocatalytic properties of TiO2 at present, particularly with respect to inclusion of the importance of defect chemistry. The research of the author in this area has attracted the prestigious award of the International Association for Hydrogen Energy. This book should be welcomed by the large research community interested in oxide semiconductors in general and TiO2 in particular, as well as the growing community interested in photocatalysis. --Professor Eric D. Wachsman, University of Maryland This book of Prof. Nowotny is addressing the increasingly urgent need for a treatise on oxide semiconductors in general and TiO2-based semiconductors in particular. ! This book, which is the first extensive survey on the science of TiO2, will be of great help to the research community involved in the studies of the properties of TiO2. --Professor Sebastian Fiechter, Helmholtz-Centre Berlin for Materials and Energy
