Available in PDF, EPUB and Kindle. Book excerpt: With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide insightful reviews of their areas of expertise, thus offering an overall picture of the state-- the art of the field. Nanostructured materials designate an increasing number of materials with designed shapes, surfaces, structures, pore systems, etc. Nanostructured materials with modified surfaces include those whose surfaces have been altered via such techniques as grafting and tethering of organic or organometallic species, or through various deposition procedures including electro, electroless and vapor deposition, or simple adsorption. These materials find important applications in catalysis, separation and environmental remediation. Materials with patterned surfaces, which are essential for the optoelectronics industry, constitute another important class of surface-modified nanostructured materials. Other materials are considered nanostructured because of their composition and internal organization.

Download or read book Nanostructured Catalysts written by Christian Hess and published by Nanoscience & Nanotechnology Series. This book was released on 2011 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book gives a comprehensive summary of the existing information on the structural/electronic properties, chemistry and catalytic properties of vanadium and molybdenum containing catalysts. As at least one of these two elements is essential to most partial oxidation catalysts the book is of great interest to advanced students of catalysis and researchers both in academia and industry. Despite major developments in the field, the last book with a similar scope was published in 1989 and therefore a new book is overdue. The book benefits largely from the fact that the subject is a major research focus at the Department of Inorganic Chemistry amongst other departments at the Fritz Haber Institute, a world leading institution for catalysis research, ensuring an up-to-date treatise. Such an integrated approach including the relation of in situ spectroscopic results from real catalysts to those of model catalytic systems has not been accomplished before. The introductory chapter discusses the importance of nanoscience for the controlled synthesis of catalysts with functional properties. The following two chapters introduce the necessary background regarding surface properties and preparation techniques, leading from a textbook level to the current state of knowledge. The following chapter starts with an extensive survey and analysis of the existing open and patent literature, which is an essential knowledge source for the development of the new generation of partial oxidation catalysts and will be of particular value to those developing new partial oxidation catalysts. In the remaining subchapters, important examples from current research on partial oxidation reactions are reviewed from experts in the field. The next chapter discusses the importance of 2- and 3-dimensional model systems for a fundamental understanding of the structure of transition metal oxide catalysts and its correlation to reactivity. These results are related to those of the real catalytic systems. The last chapter gives an outlook on research opportunities within the area of partial oxidation reactions.

Download or read book Bridging the Materials Gap in Catalysis: Reactivity Studies of Nanostructured Titania written by David A. Bennett and published by . This book was released on 2016 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface science studies of defect-free, single-crystal model catalysts have provided vital knowledge in the form of structure-activity relationships and elementary reaction mechanisms. However, there is some difficultly in extending this understanding to more complex systems, since these model catalysts typically lack the range of features that occur on the high surface area catalysts used in industry. This project seeks to bridge the gap between these two classes of materials by studying thin films of well-defined TiO2 nanocrystals with tunable size and morphology using traditional surface science techniques. This enables the controlled introduction of features lacking in single-crystal model catalysts, allowing for the formulation of more complex structure-activity relationships. The thermal- and photocatalytic reactions of methanol to produce methane, formaldehyde, dimethyl ether, and methyl formate on these TiO 2 nanoparticles were investigated using temperature programmed desorption in ultra high vacuum. Results show clear effects of nanocrystal size and shape on the activity and selectivity of these reactions. This demonstrates the value of studying nanostructured metal-oxide catalysts to better understand the relationship between fundamental catalytic knowledge and the behavior of complex heterogeneous catalysts.

Available in PDF, EPUB and Kindle. Book excerpt: One of the most pressing challenges of our time is meeting growing global energy demands while limiting human impact on the environment. To meet this challenge, new catalysts are needed to enable carbon neutral energy production processes and low cost synthesis of alternative fuels. In order to design new catalysts for such processes, fundamental understanding is needed on how the structural and chemical properties of nanostructured materials influences their surface chemistry. In this dissertation, I explore how the properties of nanoparticles, such as particle size, shape, composition, and chemical state, can be used to tune their reactivity. For this work, model nanoparticles were synthesized with well-defined structural and chemical properties, and a variety of surface science approaches were used for catalyst characterization. In particular, emphasis was placed on understanding the changes which may occur in the catalyst structure and chemical state during a reaction using advanced in situ techniques and correlating these changes to reactivity. After exploring how nanostructuring the catalyst surface can be used to tune reactivity and how dynamic changes can occur to nanocatalysts in reactive environments, these general principles are applied to a model reaction, the electroreduction of carbon dioxide, which is a promising process for synthesizing valuable products using renewable energy while consuming waste carbon dioxide. I explore the mechanisms behind how catalyst particle size, composition, and oxidation state can be used to improve activity and tune selectivity towards different carbon dioxide reduction products. Such fundamental mechanistic insights are critically needed to design efficient catalysts for this reaction.

Available in PDF, EPUB and Kindle. Book excerpt: Nanostructured ceria catalysts have shown promising results in selective oxidation reactions due to their unique properties and structures. In this field, Nallapa Reddy has conducted research on designing and developing efficient and effective ceria-based catalysts for selective oxidation reactions. The use of nanostructured ceria catalysts has gained a lot of attention in recent years due to their high surface area, unique surface chemistry, and excellent redox properties, making them ideal for catalysis. The study of nanostructured ceria catalysts involves the synthesis, modification, and characterization of ceria-based catalysts at the nanoscale level. These catalysts can be tailored to specific chemical reactions and processes by controlling their chemical synthesis, modification, and processing parameters. Chemical reactions can be optimized to maximize yield, selectivity, and specificity by understanding the chemical properties, mechanisms, and intermediates of the reaction. Various characterization techniques such as X-ray diffraction, transmission electron microscopy, scanning electron microscopy, energy dispersive spectroscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy are used to analyze the physical and chemical properties of the nanostructured ceria catalysts. The characterization results are crucial in understanding the structure-property relationship of the catalysts and to identify the optimal catalyst structure for a particular reaction. The potential applications of nanostructured ceria catalysts include catalytic oxidation reactions, redox reactions, and other chemical reactions in the field of chemical engineering. The surface properties of the catalysts can be modified to achieve the desired catalytic activity and selectivity for the specific reaction. These catalysts can be used for industrial applications in chemical synthesis, petrochemicals, and other chemical manufacturing processes. The development of nanostructured ceria catalysts has also contributed to the advancement of green chemistry by reducing the need for hazardous reagents and improving the efficiency of chemical reactions. However, the toxicity and biocompatibility of the catalysts need to be studied and considered to ensure their safe use in industrial applications and to prevent any negative impact on the environment. Overall, Nallapa Reddy's research on nanostructured ceria catalysts for selective oxidation reactions has contributed significantly to the field of catalysis and chemical engineering. The optimization of chemical reactions and the development of efficient and effective catalysts are crucial in achieving sustainable and efficient chemical manufacturing processes.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an excellent compilation of cutting-edge research in heterogeneous catalysis and related disciplines – surface science, organometallic catalysis, and enzymatic catalysis. In 23 chapters by noted experts, the volume demonstrates varied approaches using model systems and their successes in understanding aspects of heterogeneous catalysis, both metal- and metal oxide-based catalysis in extended single crystal and nanostructured catalytic materials. To truly appreciate the astounding advances of modern heterogeneous catalysis, let us first consider the subject from a historical perspective. Heterogeneous catalysis had its beginnings in England and France with the work of scientists such as Humphrey Davy (1778–1829), Michael Faraday (1791–1867), and Paul Sabatier (1854–1941). Sabatier postulated that surface compounds, si- lar to those familiar in bulk to chemists, were the intermediate species leading to catalytic products. Sabatier proposed, for example, that NiH moieties on a Ni sur- 2 face were able to hydrogenate ethylene, whereas NiH was not. In the USA, Irving Langmuir concluded just the opposite, namely, that chemisorbed surface species are chemically bound to surfaces and are unlike known molecules. These chemisorbed species were the active participants in catalysis. The equilibrium between gas-phase molecules and adsorbed chemisorbed species (yielding an adsorption isotherm) produced a monolayer by simple site-filling kinetics.

This book was released on 2019-05-10 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoparticles exhibit a range of different properties when compared to bulk materials. Their high surface-area to volume ratio makes them particularly attractive for use as catalysts and recent years have seen an explosion of research in this area. The ability to fine-tune the size and structure of nanoparticles means that it is possible to design catalytic materials for improved activity or specificity. As catalysis is one of the key technologies for more sustainable production of both chemicals and energy, the past few years have seen increasing numbers of nanomaterials reported for these applications. Depending on the application, a number of different catalyst synthesis and optimization protocols can be used. This book provides comprehensive links between the design and fabrication method for nanoparticles and their catalytic performance (activity, selectivity and stability) in various applications. Presenting an introduction to the concept of catalyst design and recent developments in the preparation and characterisation of nanomaterials, followed by several chapters on the design of catalysts for specific applications, this book is a valuable resource for researchers working on catalytic reactions, industrial processes and nanomaterial applications.
