Book excerpt: The photoinduced splitting of water into hydrogen and oxygen has evoked great interest in recent years as a means for energy storag eand fuel production. Photoinduced reduction of water to hydrogen, using visible light, has been described using heterogeneous or homogeneous catalysts. However, the complementary part involving the oxidation of water to oxygen is required in order to create a cyclic artificial 'photosynthetic' fuel system. The major difficulty assocaited with the photooxidation of water involves the requirement for a four electron transfer to produce oxygen. A stepwise one-electron oxidation of water is unfavorable due to the implied formation of active hydroxyl radicals. Very recently, it has been reported that RuO2 can serve as a heterogeneous charge storage catalyst for oxygen production. On the basis of the limited knowledge about natural photosynthesis, in which manganese ions play an important role in oxygen evolution, synthetic manganese complexes, and in particular dimeric complexes, have been proposed as potential catalysts for oxygen production. So far, efforts directed toward this goal have been unsuccessful. Consequently, using a manganese complex, they attempted to perform a photoinduced oxidation of water whereby the active oxygen is transferred to a trapping substrate. In such a way, the requirement for a dimerization process to evolve molecular oxygen is avoided. They wish to report a photoinduced redox cycle sensitized by a manganese porphyrin, 5-(4′-hexadecylpyridium)-10, 15, 20-tri (4′-pyridyl)-porphinatomanganese(III) (abbreciated to Pn-Mn{sup III}) in which the resultant reaction is the oxidation of water and trapping of the single oxygen atom by a substrate (triphenylphosphine).

Download or read book Natural and Artificial Photosynthesis written by Reza Razeghifard and published by John Wiley & Sons. This book was released on 2013-08-23 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical book explores current and future applications of solar power as an unlimited source of energy that earth receives every day. Photosynthetic organisms have learned to utilize this abundant source of energy by converting it into high-energy biochemical compounds. Inspired by the efficient conversion of solar energy into an electron flow, attempts have been made to construct artificial photosynthetic systems capable of establishing a charge separation state for generating electricity or driving chemical reactions. Another important aspect of photosynthesis is the CO2 fixation and the production of high energy compounds. Photosynthesis can produce biomass using solar energy while reducing the CO2 level in air. Biomass can be converted into biofuels such as biodiesel and bioethanol. Under certain conditions, photosynthetic organisms can also produce hydrogen gas which is one of the cleanest sources of energy.

Download or read book Energy Production and Storage written by Robert H. Crabtree and published by John Wiley & Sons. This book was released on 2013-02-19 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy production and storage are central problems for our time. In principle, abundant energy is available from the sun to run the earth in a sustainable way. Solar energy can be directly harnessed by agricultural and photovoltaic means, but the sheer scale of the energy demand poses severe challenges, for example any major competition between biomass production and food production would simply transfer scarcity from energy to food. Indirect use of solar energy in the form of wind looks also promising, especially for those regions not blessed with abundant sunlight. Other modes such as tidal and wave energy may well become important niche players. Inorganic chemistry plays a decisive role in the development of new energy technologies and this Volume covers some promising modes of alternative energy production and storage that minimize the atmospheric burden of fossil-derived carbon monoxide. No one production or storage mode is likely to dominate, at least at first, and numerous possibilities need to be explored to compare their technical feasibility and economics. This provides the context for a broad exploration of novel ideas that we are likely to see in future years as the field expands. This Volume covers a wide range of topics, such as: - Water splitting, only water is a sufficiently cheap and abundant electron source for global exploitation; - Energy conversion by photosynthesis; - Molecular catalysts for water splitting; - Thermochemical water splitting; - Photocatalytic hydrogen production; - Artificial photosynthesis, progress of the Swedish Consortium; - Hydrogen economy; - Reduction of carbon dioxide to useful fuels; - Conversion of methane to methanol; - Dye sensitized solar cells; - Photoinitiated electron transfer in fuel cells; - Proton exchange membranes for fuel cells; - Intermediate temperature solid oxide fuel cells; - Direct Ethanol fuel cells; - Molecular catalysis for fuel cells; - Enzymes and microbes in fuel cells; - Li-Ion batteries; - Magic Angle Spinning NMR studies of battery materials; Supercapacitors and electrode materials. About EIC Books The Encyclopedia of Inorganic Chemistry (EIC) has proved to be one of the defining standards in inorganic chemistry, and most chemistry libraries around the world have access either to the first or second print edition, or to the online version. Many readers, however, prefer to have more concise thematic volumes, targeted to their specific area of interest. This feedback from EIC readers has encouraged the Editors to plan a series of EIC Books, focusing on topics of current interest. They will appear on a regular basis, and will feature leading scholars in their fields. Like the Encyclopedia, EIC Books aim to provide both the starting research student and the confirmed research worker with a critical distillation of the leading concepts in inorganic and bioinorganic chemistry, and provide a structured entry into the fields covered. This volume is also available as part of Encyclopedia of Inorganic Chemistry, 5 Volume Set. This set combines all volumes published as EIC Books from 2007 to 2010, representing areas of key developments in the field of inorganic chemistry published in the Encyclopedia of Inorganic Chemistry.

Download or read book Structure and Function written by Peter Comba and published by Springer Science & Business Media. This book was released on 2009-12-02 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: The art of chemistry is to thoroughly understand the properties of molecular compounds and materials and to be able to prepare novel compounds with p- dicted and desirable properties. The basis for progress is to fully appreciate and fundamentally understand the intimate relation between structure and function. The thermodynamic properties (stability, selectivity, redox potential), reactivities (bond breaking and formation, catalysis, electron transfer) and electronic properties (spectroscopy, magnetism) depend on the structure of a compound. Nevertheless, the discovery of novel molecular compounds and materials with exciting prop- ties is often and to a large extent based on serendipity. For compounds with novel and exciting properties, a thorough analysis of experimental data – state-of-the-art spectroscopy, magnetism, thermodynamic properties and/or detailed mechanistic information – combined with sophisticated electronic structure calculations is p- formed to interpret the results and fully understand the structure, properties and their interrelation. From these analyses, new models and theories may emerge, and this has led to the development of ef cient models for the design and interpre- tion of new materials and important new experiments. The chapters in this book therefore describe various fundamental aspects of structures, dynamics and physics of molecules and materials. The approaches, data and models discussed include new theoretical developments, computational studies and experimental work from molecular chemistry to biology and materials science.
