Water is one of the essential resources on our planet. Therefore, fresh water and the recycling of waste-water are very important topics in various areas. Energy-saving green technologies are a demand in this area of research. Photocatalysis comprises a class of reactions which use a catalyst activated by light. These reactions include the decomposition of organic compounds into environmental friendly water and carbon dioxide, leading to interesting properties of surfaces covered with a photocatalyst: they protect e.g. against incrustation of fouling matter, they are self-cleaning,…mehr

Produktbeschreibung
Water is one of the essential resources on our planet. Therefore, fresh water and the recycling of waste-water are very important topics in various areas. Energy-saving green technologies are a demand in this area of research. Photocatalysis comprises a class of reactions which use a catalyst activated by light. These reactions include the decomposition of organic compounds into environmental friendly water and carbon dioxide, leading to interesting properties of surfaces covered with a photocatalyst: they protect e.g. against incrustation of fouling matter, they are self-cleaning, antibacterial and viricidal. Therefore, they are attractive candidates for environmental applications such as water purification and waste-water treatment. This book introduces scientists and engineers to the fundamentals of photocatalysis and enlightens the potentials of photocatalysis to increase water quality. Also, strategies to improve the photocatalytic efficacy are pointed out: synthesis of better photocatalysts, combination of photocatalysis with other technologies, and the proper design of photocatalytic reactors. Implementation of applications and a chapter on design approaches for photocatalytic reactors round off the book. 'Photocatalysis and Water Purification' is part of the series on Materials for Sustainable Energy and Development edited by Prof. G.Q. Max Lu. The series covers advances in materials science and innovation for renewable energy, clean use of fossil energy, and greenhouse gas mitigation and associated environmental technologies.

Autorenporträt
Pierre Pichat, as "Directeur de Recherche" with the CNRS (National Center for Scientific Research, France), has been active in heterogeneous photocatalysis for many years and has founded in Lyon, France, a laboratory principally based on this field. His research activity has concerned both basic investigations (role of photo-generated active species, reaction pathways, relationships between the efficacy and the characteristics of the materials, etc.) and applications regarding not only the photocatalytic treatment of water, but also self-cleaning materials and the purification of indoor air. He has been invited to publish reviews of these various domains. He has been and is a frequent invited lecturer at Conferences. He has received an International Appreciation Award acknowledging his pioneering contributions. Over the years, he has served on CNRS-related Committees on diverse aspects of chemistry, such as catalysis, photochemistry, solar chemistry and environmental chemistry. He has been the coordinator or advisor of European Community projects on photocatalysis. He has been asked by Institutions of various countries to evaluate projects on environmental chemistry. He has been and is a member of International Scientific Committees of Journals and Conferences.
