Book Description
To gain useful insight into the mechanistic details of the TiO2 photocatalyzed oxidation of halogenated organic compounds, the intermediates produced during the photocatalytic degradation of 4-chlorophenol (4-CP) have been compared with those produced during [gamma]-radiolysis. Photocatalytic degradation of 4-CP produces aromatic intermediates consistent with [gamma]-radiolytic hydroxyl radical oxidation, but the distribution of the intermediates differs. The surface area of TiO2 has an important influence on the intermediate distribution suggesting that the presence of surface influences the reaction pathway. The course of photocatalytic transformation of 4-CP involves a combination of hydroxyl radical oxidation, direct electron transfer and surface chemical reactions contributing to the disappearance of 4-CP and its reaction intermediates in TiO2 slurries.

Book Description
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.

Book Description
As phenols represent an important functional group category, The Chemistry of Phenols is an essential addition to any chemistry library. Written by experts, all aspects concerning these compounds are covered making this an essential reference book, bringing together invaluable information into one source for organic, organometallic chemists as well as chemists from a variety of other organic sub-disciplines. Single Source information – essential for organic, organometallic and chemists from organic sub-disciplines Covers phenols as anti-oxidants, synthetic intermediates, polymers and hydrogen bonds Discusses electrophilic and photochemical reactions The Patai Series publishes comprehensive reviews on all aspects of specific functional groups. Each volume contains outstanding surveys on theoretical and computational aspects, NMR, MS, other spectroscopic methods and analytical chemistry, structural aspects, thermochemistry, photochemistry, synthetic approaches and strategies, synthetic uses and applications in chemical and pharmaceutical industries, biological, biochemical and environmental aspects. To date, over 100 volumes have been published in the series. Also Available Online The Chemistry of Phenols as well as the other titles within the Patai Series is also available in electronic format on Wiley InterScience. All new titles will be published online and a growing list of older titles will be added every year.
