Available in PDF, EPUB and Kindle. Book excerpt: This investigation studied the photocatalytic oxidation of light alkanes using photocatalytic thin films. In the research presented, nearly complete oxidation of isobutane, n-butane and propane using ZrO2/TiO2 thin films in a single pass reactor was demonstrated. The importance of reactor design on the effectiveness of the photocatalytic reaction is discussed in terms of photocatalyst packing and adequate illumination for catalyst activation. The influence of relative humidity in the contaminant feed stream and the reactor operating temperature were evaluated to establish optimal operating conditions for the photocatalytic reactor. Further photocatalytic studies used propane as a probe compound to investigate metal-modification of photocatalytic thin films as a means to improve propane oxidation and mineralization. Six precious metals (Ag, Au, Pd, Pt, Rh, and Ru) were tested at 1 weight percent loadings in TiO2, SiO2/TiO2, and ZrO2/TiO2 thin films. The photocatalytic reactor was operated at temperatures up to 100 C with the expectation that a thermal catalytic enhancement due to the precious metals would be observed. Propane conversion data revealed that at 1% loading, the addition of metals to the thin films reduced the activity for conversion of propane, regardless of temperature. However, the reactor temperature iii significantly affected light irradiance. Reaction rates adjusted for the influence of temperature on reactor irradiance revealed the highest reaction rates occurred at 100 C, but evaluation of Langmuir-Hinshelwood-Hougen-Watson kinetics showed that temperature significantly reduced the surface adsorption of propane. Of the 21 materials tested, an unmodified ZrO2/TiO2 thin film had the best activity for propane conversion and mineralization. Lastly, a novel method to investigate the photoinduced change in surface potential of photocatalytic thin films was investigated.

Book excerpt: Research for the development of more efficient photocatalysts has experienced an almost exponential growth since its popularization in early 1970’s. Despite the advantages of the widely used TiO2, the yield of the conversion of sun power into chemical energy that can be achieved with this material is limited prompting the research and development of a number of structural, morphological and chemical modifications of TiO2 , as well as a number of novel photocatalysts with very different composition. Design of Advanced Photocatalytic Materials for Energy and Environmental Applications provides a systematic account of the current understanding of the relationships between the physicochemical properties of the catalysts and photoactivity. The already long list of photocatalysts phases and their modifications is increasing day by day. By approaching this field from a material sciences angle, an integrated view allows readers to consider the diversity of photocatalysts globally and in connection with other technologies. Design of Advanced Photocatalytic Materials for Energy and Environmental Applications provides a valuable road-map, outlining the common principles lying behind the diversity of materials, but also delimiting the imprecise border between the contrasted results and the most speculative studies. This broad approach makes it ideal for specialist but also for engineers, researchers and students in related fields.

Book excerpt: Materials science includes those parts of chemistry and physics that deal with the properties of materials. It encompasses four classes of materials, the study of each of which may be considered a separate field: metals; ceramics; polymers and composites. Materials science is often referred to as materials science and engineering because it has many applications. Industrial applications of materials science include processing techniques (casting, rolling, welding, ion implantation, crystal growth, thin-film deposition, sintering, glassblowing, etc.), analytical techniques (electron microscopy, x-ray diffraction, calorimetry, nuclear microscopy (HEFIB) etc.), materials design, and cost/benefit tradeoffs in industrial production of materials. This book presents new research directions in the very new field of nanomaterials.

Traditionally, industrial waste gases have primarily been treated through physical or chemical methods. The search for new, efficient, and cost-effective alternative technologies has led to the development and, more recently, the improvement of gas phase bioreactors. This book is the first single text to provide a complete, comprehensive picture of all major biological reactors suitable for solving air pollution problems. The text describes the main features and covers the major aspects, from microbiological to engineering, as well as economic aspects, of the different types of bioreactors. The book also presents an in-depth review of the subject, from fundamental bench-scale research to industrial field applications related to the operation of full-scale systems successfully treating polluted air in Europe and the United States. Material dedicated to more conventional non-biological technologies has also been included, to provide a complete overview of the different alternative treatment processes. Audience: The different chapters have been written by international experts, as a result of a fruitful collaboration between European and American scientists and engineers. The resulting text is a high quality, valuable reference tool for a variety of readers, including graduate and postgraduate students, researchers, professors, engineers, and those professionals who are interested in environmental engineering and, more specifically, in innovative air pollution control technologies.

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.
