Book Description
Energy Resources through Photochemistry and Catalysis reviews the state of the art in the development of energy conversion devices based on catalytic and photochemical reactions. The focus is on catalysis of redox reactions and their application to the photocleavage of water, reduction of carbon dioxide, and fixation of nitrogen. Some fundamental aspects of catalysis as it relates to processes of light energy harvesting and charge separation in photochemical or photoelectrochemical conversion systems are also discussed. This monograph is comprised of 16 chapters covering light-induced redox reactions and reaction dynamics in organized assemblies such as micelles, colloidal metals, or semiconductors, together with strategies for molecular engineering of artificial photosynthetic devices. The principles of electrochemical conversion of light energy via semiconductor electrodes or semiconducting particles are also considered. Furthermore, thermodynamic characteristics for some reactions that can be utilized for storage of solar energy in the form of chemical energy are examined. The remaining chapters look at the role of porphyrins in natural and artificial photosynthesis; the use of semiconductor powders and particulate systems for photocatalysis and photosynthesis; and hydrogen-generating solar cells based on platinum-group metal activated photocathodes. This text will be a useful resource for scientists and policymakers concerned with finding alternative sources of energy.

Book Description
Any mention of the "greenhouse effect" tends to ignite controversy. While the rising atmospheric concentrations of greenhouse gases-especially carbon dioxide- are certainly among the most pressing issues today, theoretical and perceived consequences have been subject to conjecture and misinformation. That raging debate has obscured an important fact: scientists and engineers are hard at work on methods to reduce CO2 emissions, and devise practical methods for their remediation. Greenhouse Gas Carbon Dioxide Mitigation: Science and Technology sheds light on the most recent advancements, documented by two of the world's leading researchers on CO2. Aware of the complexity and still-unknown factors behind climatic change, the authors consider the need to make CO2 mitigation viable for both environmental and economic gain. To that end, Professor Halmann offers new insights into interesting chemical pathways for the conversion of CO2 to useful products. Steinberg adds real-life engineering solutions, applicable to heavy CO2-producing industrial processes, and improving efficiency of energy conversion. Exciting theories and pilot projects are also testing the potential for CO2 utilization, conversion, reduction, and disposal. Greenhouse Gas Carbon Dioxide Mitigation: Science and Technology reports on the use of biomass, such as ocean fertilization and "energy farms," to put CO2 to practical and safe use. Professional and academic readers involved with CO2 research will find Greenhouse Gas Carbon Dioxide Mitigation: Science and Technology an invaluable roadmap for information and inspiration-a way to move beyond argument, and into action.

Book Description
Photosensitization and photocatalysis refer to processes by which permanent chemical transformations are induced on substrates (organic/inorganic) by radiation to which the substrates themselves are transparent. Such transformations can be highly specific, very efficient, and occur under mild conditions. Herein lies the power of photochemical methods for possible applications in the field of conversion and storage of solar energy. This book provides a recent survey of the progress in this important area in catalysis, with an emphasis on inorganic complexes and organometallic compounds as the key light aborbers. The book is organized in three parts: fundamentals, followed by applications. Discussions cover a wide variety of photosensitized or photocatalyzed reactions: decomposition of water, reduction of CO2 and CO; spectral sensitization in photoelectrochemical cells; transformations (oxidation, reduction, isomerization, hydrogenation, dehydrogenation, carbonylation, etc.) of organics such as alkanes, alkenes, alcohols, etc. In view of the variety of systems (sensitizers, substrates) and the topics covered, the volume is unique in the field of photochemistry and will appeal to academic and industrial researchers in various subdisciplines of chemistry, material science and catalysis.

Book Description
Students contemplating careers in chemistry, whether in research, practice, or academia, obviously need a solid grounding in proper research methodology, reasoning, and analysis. However, there are few resources available that efficiently and effectively introduce these concepts and techniques and inspire students to undertake advanced research, particularly in the area of catalysis. Catalysis: Principles and Applications evolved out of a special, resoundingly successful short course for graduate students interested in catalysis. It covers nearly the entire gamut of the subject, from its fundamentals to its modern, applied aspects. The chapters were contributed by catalysis specialists from leading academic institutions, national laboratories and industrial R&D labs. Because they are based on the authors' lecture notes, each chapter is highly accessible and for the most part self-contained. Topics include various spectroscopic methods, biocatalysis, x-ray and thermal analysis, photocatalysis, and recent developments, such as solid acid catalysts, fine chemical synthesis, and computer-aided catalyst design. The book also contains discussions on a variety of modern applications, including environmental pollution control, petroleum refining, fuel cells, and monomolecular films. Logically presented, well-illustrated, and thoroughly referenced, Catalysis: Principles and Applications offers an outstanding basis for courses in catalysis. It not only imparts the fundamentals, synthesis, characterization, and applications of catalysis, but does so in a way that will motivate students to pursue more advanced studies and ultimately careers in the field.

Book Description
This book explains the use of nanocrystalline semiconductors in the harvesting of energy from solar light. It introduces promising methodology and technology which may help to increase the efficiency of light harvesting – one of the major challenges on the way toward sustainable energy generation.The book starts with a general introduction to the photochemistry of semiconductor nanocrystals. In the introductory chapter, the author also provides a frank and critical discussion on perspectives and limitations of the photocatalytic processes for solar light conversion including a historical account on semiconductor photocatalysis. He discusses that (and also why) it is a long way from laboratory prototypes to real sustainable technologies.The following chapters outline the conversion of solar light energy in semiconductor nanophotocatalysis on the one hand, and to (electric) energy in nanocrystalline semiconductor-based solar cells on the other hand. Topics addressed include nanophotocatalytic hydrogen production, artificial photosynthesis, quantum-dot sensitized liquid-junction and bulk heterojunction solar cells. Perspectives and opportunities, but also bottlenecks and limitations are discussed and the novel systems compared with established technology, such as classical silicon solar cells. While readers in this way learn to understand the basics and get introduced to the current research in the field, the final chapter provides them with the necessary knowledge about methodology, both in synthesis and characterization of semiconductor nanophotocatalysts and semiconductor nanomaterials, including examples for the practice of photocatalytic experiments and the studies of semiconductor-based solar cells.
