Book excerpt: Recent years have seen an expansion in speciality uses of activated carbons including medicine, filtration, and the purification of liquids and gaseous media. Much of current research and information surrounding the nature and use of activated carbon is scattered throughout various literature, which has created the need for an up-to-date comprehensive and integrated review reference. In this book, special attention is paid to porosities in all forms of carbon, and to the modern-day materials which use activated carbons - including fibres, clothes, felts and monoliths. In addition, the use of activated carbon in its granular and powder forms to facilitate usage in liquid and gaseous media is explored. Activated Carbon will make essential reading for Material Scientists, Chemists and Engineers in academia and industry. - Characterization of porosity - The surface chemistry of the carbons - Methods of activation and mechanisms of adsorptio - Computer modelling of structure and porosity within carbons - Modern instrumental analytical methods

Book excerpt: Carbon materials form pores ranging in size and morphology, from micropores of less than 1nm, to macropores of more than 50nm, and from channel-like spaces with homogenous diameters in carbon nanotubes, to round spaces in various fullerene cages, including irregularly-shaped pores in polycrystalline carbon materials. The large quantity and rapid rate of absorption of various molecules made possible by these attributes of carbon materials are now used in the storage of foreign atoms and ions for energy storage, conversion and adsorption, and for environmental remediation. Porous Carbons: Syntheses and Applications focuses on the fabrication and application of porous carbons. It considers fabrication at three scales: micropores, mesopores, and macropores. Carbon foams, sponges, and 3D-structured carbons are detailed. The title presents applications in four key areas: energy storage, energy conversion, energy adsorption, including batteries, supercapacitors, and fuel cells and environmental remediation, emphasizing the importance of pore structures at the three scales, and the diffusion and storage of various ions and molecules. The book presents a short history of each technique and material, and assesses advantages and disadvantages. This focused book provides researchers with a comprehensive understanding of both pioneering and current synthesis techniques for porous carbons, and their modern applications. - Presents modern porous carbon synthesis techniques and modern applications of porous carbons - Presents current research on porous carbons in energy storage, conversion and adsorption, and in environmental remediation - Provides a history and assessment of both pioneering and current cutting-edge synthesis techniques and materials - Covers a significant range of precursor materials, preparation techniques, and characteristics - Considers the future development of porous carbons and their various potential applications

Book excerpt: In recent years the Japanese have funded a comprehensive study of carbon materials which incorporate other elements including boron, nitrogen and fluorine, hence the title of the project "Carbon Alloys".Coined in 1992, the phrase "Carbon Alloys" can be applied to those materials mainly composed of carbon materials in multi-component systems. The carbon atoms of each component have a physical and/or chemical interactive relationship with other atoms or compounds. The carbon atoms of the components may have different hybrid bonding orbitals to create quite different carbon components.Eiichi Yasuda and his team consider the definition of Carbon Alloys, present the results of the Carbon Alloys projects, describe typical Carbon Alloys and their uses, discuss recent techniques for their characterization, and finally, illustrate potential applications and future developments for Carbon Alloy science. The book contains over thirty chapters on these studies from as many researchers.The most modern of techniques, particularly in the area of spectroscopy, were used as diagnostic tools, and many of these are applicable to pure carbons also. Porosity in carbons received considerable attention.

Available in PDF, EPUB and Kindle. Book excerpt: Porosity in carbons often means different things to different people depending largely on the different applications of the various carbon materials. On the one hand, users involved in gas purification or respiratory protection are concerned primarily with microporosity, and at the other extreme, the user of carbon in the form of metallurgical coke is concerned with macroporosity because of its influence on the mechanical properties of the coke. Between these extremes there is a range of applications which rely on different aspects of the nature of the porous structure and the characterization required reflects the particular application in mind. This characterization of a wide diversity of porous structures presents some problems. However recent developments have produced some solutions, for example computerized image analysis has facilitated the measurement of pore shape and size. The eleven chapters in this book present an analysis of the current methods of characterization and the role of various aspects of carbon porosity in some representative and diverse applications.

Book excerpt: Over the past few decades, mankind has observed an unprecedented and remarkable growth in industry, resulting in a more prosperous lifestyle for peoples of many countries. In developing countries, however, explosive industrial growth is just now beginning to raise the living standards of the people. Most industries, especially in these developing countries, are still powered by the burning of fossil fuels; con- quently, a lack of clean energy resources has caused environmental pollution on an unprecedented large and global scale. Toxic wastes have been relentlessly released into the air and water leading to serious and devastating environmental and health problems while endangering the planet and life itself with the effects of global warming. To address these urgent environmental issues, new catalytic and photocatalytic processes as well as open-atmospheric systems are presently being developed that can operate at room temperature while being totally clean and ef?cient and thus environmentally harmonious. Essential to technologies harnessing the abundant solar energy that reaches the earth are the highly functional photocatalytic proce- es that can utilize not only UV light, but also visible light.
