Titanium oxide-based catalysts are especially promising as one of the most stable, non toxic, easily available photofunctional materials known today. Previously, the successful development of second-generation titanium oxide photocatalysts using an advanced metal ion-implantation technique led to reactions that could be induced not only with UV but also visible light. Since then, not only has efficiency been improved but new materials and synthesis methods have also been developed. This book will cover the various approaches in the design of efficient titanium oxide-based photocatalysts by such methods as sol-gel, precipitation, dip-coating, metal implantation and sputtering deposition. It will cover the most recent advances in TiO2 research and their potential applications as well as detailed and fundamental characterization studies on the active sites and mechanisms behind the reactions at the molecular level. The book should serve not only as a text for research into photochemistry and photocatalysis but also to inspire more applications into environmentally-harmonious technologies.

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.

Work should be of interest and significance not only in the academic community but also for the commercial and industrial sector Very few competitors, and those already existing include old editions Work will include innovative techniques and will also discuss future prospects Anpo is one of the world's leading photochemists

Klappentext
This book focuses on the various approaches used in the design and development of highly efficient, visible light responsive titanium oxide-based photocatalysts by applying such methods as sol-gel, precipitation, dip-coating, metal ion-implantation, and magnetron sputtering deposition. Titanium oxide-based photocatalysts and related catalysts are especially promising to investigate since they are stable, non-toxic, readily available, and highly efficient photofunctional materials. This book discusses the fundamental characterization studies carried out on the active sites and mechanisms behind photochemical reactions at the molecular level, as well as their potential applications. The book serves not only as a text for research into photochemistry and photocatalysis, but also explores the field of green technologies by experts in academia and industry. This book will appeal to those interested in research on the environmental impact of materials, catalysis, and photocatalysis.
