Available in PDF, EPUB and Kindle. Book excerpt: The present monograph attempts to unify these diverse and exciting new developments within a common framework. First, the physical principles underlying heterogenous electron-transfer processes are outlined in a concise way and are compared to the homogeneous counterpart. This analysis includes the notion of the Fermi level in liquids and solids as well as the distribution of electronic energy levels in solids and liquids. A comparison is made between the salient kinetic features of homogeneous and heterogeneous electron transfer reactions. This establishes the basis for the subsequent treatment of the transduction of excitation energy and photo-initiated electron transfer in organized molecular assemblies, such as micelles, vesicles and monolayers. Transmembrane redox processes are critically reviewed. Particular attention is given to semiconductor electrodes and particles. This includes a discussion of quantum size effects, the nature of space charge layers as well as surface states and the dynamics of charge carrier-induced redox reactions at the semiconductor solution interface. These processes are of fundamental importance in such diverse fields as photochromism, electrochromic displays, electroreprography and photography, information storage, photocatalysis, photodegradation of paints, and solar energy conversion.

Book excerpt: Ever since the oil crisis of 1973, researchers in various fields of chemistry have proposed various schemes to conserve energy, as well to convert the sun's abundant and limitless supply of energy to produce chemical fuels (e. g. , hydrogen from water, . •. ). The enthusiasm had no previous parallel in the mid-1970's. Unfortunately, despite the several good proposals, the results have proven - in retrospect - somewhat disappointing from an economic viable point of view. The reasons for the meagre results are manyfold not the least of which are the experimental difficulties encountered in storage systems. Moreover, the lack of a concerted, well orchestrated interdisciplinary approach has been significant. By contrast, the chemical advances made in the understanding of the processes involved in such schemes have been phenomenal. A recent book on this issue ( M. Gratzel, Energy Resources through Photochemistry and Catalysis, 1983) is witness to the various efforts and approaches taken by researchers. In the recent years, many more groups have joined in these efforts, and the number of papers in the lit~rature is staggering ! One of the motives for organizing this NATO Advanced Research Workshop stemmed from our view that it was time to take stock of the accomplishments and rather than propose new schemes, it was time to consider seriously avenues that are most promising.

This book was released on 2012-12-06 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book collects the lectures and the status reports delivered during the "Eighth International Conference on Photochemical Conversion and Storage of Solar Energy", IPS-8, held in Palermo (Italy) from 15th to 20th of July 1990. As usual, the main theme of the Conference was that of making the point about the trends and the developments of the studies related to the photochemical exploitation of solar energy and also to report the main lines of potential applications. Therefore the contributions reflect this point; they vary from those reporting basic and fundamental theories to those reporting cases of possible applications. For the sake of following the logical line which links each other the various contributions, we report the six areas in which the main theme of the conference was devided: (a) Electron and energy transfer in homogeneous and heterogeneous systems; (b) Photosynthesis: organized assemblies and biomimetic systems; (c) Photoelectrochemistry; (d) Photocatalysis: homogeneous and heterogeneous regime; (e) Environment: photochemical and photocatalytic processes; (f) Solar energy materials and photochemical engineering. It remains now to thank persons and institutions which made possible the organization of the Conference. The persons to thank are all the members of the International and National Organizing Committees and in particular Prof. A.Sclafani and Dr. L.Palmisano whose efforts were essential for the success of the Conference.

Available in PDF, EPUB and Kindle. Book excerpt: Photochemical Conversion and Storage of Solar Energy contains the proceedings of the Third International Conference on Photochemical Conversion and Storage of Solar Energy held in Boulder, Colorado, on August 3-8, 1980. The papers review the state of the art in the areas of photochemistry and photoelectrochemistry in the context of solar energy conversion and storage. Topics covered include photosynthetic quantum conversion; biomimetic systems for solar energy conversion; and photochemical electron transfer reactions in homogeneous solutions. This volume is comprised of 11 chapters and begins by describing an artificial photosynthetic system that can capture solar quanta and convert them into a stable chemical form. The discussion then turns to biomimetic approaches to solar energy conversion; fluorescent concentrators for photovoltaic cells; requirements for homogeneous photoredox chemistry in inorganic systems; and the use of inorganic components coupled with catalysts in heterogeneous assemblies for photochemical water splitting. The following chapters focus on photogalvanic cells, electrochemical photovoltaic cells, and photoelectrosynthetic reactions at the semiconductor-electrolyte interface. The final chapter examines the thermodynamic limits on photoconversion and storage of solar energy. This monograph will be of interest to chemists and other scientists concerned with the photochemical aspects of solar energy conversion and storage.

This book was released on 2001-05-02 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electron transfer is the most important process to take place in natural and artificial chemical systems, playing a fundamental role, for example, in photosynthesis as well as in photography. Electron transfer reactions - oxidations and reductions - are involved in, among others, a variety of energy conversion processes, analytical methods, synthetic strategies, and information processing systems. This five-volume work is the only comprehensive yet up-to-date reference on electron transfer processes. Following a foreword by Nobel prize-winner R. A. Marcus, renowned experts from all over the world provide an interdisciplinary overview of every aspect of electron transfer including theoretical-physicochemical backgrounds, latest analytical techniques to identify, monitor and measure the rate of electron transfer, utilizing electron transfer reactions in organic synthesis and catalysis, electron transfer in the gas phase or in special heterogeneous systems such as zeolites or sensitized electrodes. Other central issues are the study of biological systems and the biomimetic electron transfer processes in artificial supramolecular systems. Finally, a complete volume is dedicated to the application of electron transfer in molecular-level electronics, imaging processes and energy conversion. Each chapter is complemented by numerous tables, formulae and illustrations providing an indispensable wealth of information. All references are cross-indexed throughout the work for easy access to this highly complex topic. Whether for quickly looking-up a keyword or as a thorough introduction to a special aspect, this is an essential handbook for everyone working in the field, from experts to postgraduates, from synthetic chemists, physicochemists or biochemists to research groups in material sciences.

Book excerpt: Devoted exclusively to the basic theories, concepts and applications of light-initiated electron transfer processes, Fundamentals of Photoinduced Electron Transfer is the first book to deliver an introductory-level account of this highly active research area in a concise and easy-to-follow pedagogical manner. No prior knowledge of photochemistry is assumed or required. The author introduces essential background information on photochemistry and electrochemistry and presents a systematic account of the photoinduced electron transfer process. He carefully explains the fundamental thermodynamic equation governing the photoinduced electron, explores the diverse realm of electron photochemistry reactions and provides a survey of today's most important applications. Coverage also features discussion on classical and nonclassical theories to faster insight on a host of underlying molecular and environmental factors. Novel applications such as solar energy conversion, artificial photosynthesis, semiconductor technology, organized assemblies, and molecular electronic devices are described in appropriate detail. Fundamentals of Photoinduced Electron-Transfer is of special value as both a learning tool and working reference in photochemistry, physical chemistry, molecular physics, spectroscopy and electrochemistry.
