Photocatalysis, hold great promise for delivering these ground-breaking technologies, is a truly environmentally friendly process where irradiation, either near UV or solar light, and promotes photoexcitation of semiconductor solid surfaces. As a result, mobile electrons and positive surface charges are generated. These excited sites and electrons accelerate oxidation and reduction reactions,which are essential steps for pollutant degradation. Photocatalysis and its related technologicalissues have been strongly influenced by recent publications.
The treatment of the various engineering and science presented in "Advances of Photocatalysis Science & Engineering for Ti02-Based Photocatalysts" will show how a process concerned their formulation of the subject flows naturally from the fundamental principles and theory of chemistry,physics, and mathematics. This emphasis on fundamental science recognizes that engineering practice has in recent years become more firmly based on scientific principles rather than its earlier dependency on the empirical accumulation of facts. The present book aims at offering a comprehensive overview ofthe state-of-the-art photocatalytic science and technology. It will be seen in this book of the fundamentals and selected applications of photocatalysis, principally on titanium dioxide based photocatalyst, that there is a host of reports concerned the waste water and gaseous pollutants treatment. The work will be divided into several sections as follows.

内容简介
The past 40 years have seen the emergence worldwide of a growing desire to take positive actions to restore and protect our environment from the degrading effects of all forms of pollution. Since this pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for "zero discharge" can be construed as an unrealistic demand for zero waste. However, as long as waste exists, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. In recent years, the international environment community, especially in China, has been increasingly concerned about the stresses imposed on the natural environment by many chemical and energy-generating processes. As a result, the whole world is witnessing an accelerated development and implementation of new green technologies which are called to provide ecologically responsible solutions for the much needed supply of drinking water and clean air.作者简介
