Available in PDF, EPUB and Kindle. Book excerpt: Mixed oxides are the most widely used catalyst materials for industrial catalytic processes. The principal objective of this book is to describe systematically the mixed oxide catalysts, from their fundamentals through their practical applications. After describing concisely general items concerning mixed oxide and mixed oxide catalysts, two important mixed oxide catalyst materials, namely, heteropolyacids and perovskites, are taken as typical examples and discussed in detail. These two materials have several advantages: 1. They are, respectively, typical examples of salts of oxoacids and double oxide, that is, the two main categories of mixed oxides in solid state chemistry. 2. Both exhibit excellent catalytic performance in nearly crystalline state and are used in several industrial applications. 3. They have studied for many years. In addition, metal oxides functioning as a catalyst support (carrier) are included. Although the supports are very important in practical applications, and tremendous progress has been made in the past decades, few systematic reviews exist. It is notable that heteropolyacids and perovskite exhibit unique performance when used as a support. Fundamental catalytic science and technology and solid state chemistry necessary is presented for the proper understanding of mixed oxide catalysts as well as for R&D. For the latter, the concept of design of practical catalysts is very important. This is considered throughout the book. Systematically describes design principles of mixed oxide catalysts Shows how catalysis and solid-state chemistry of metal oxides are inter-related Covers all useful basic concepts of mixed oxide catalysis

Download or read book Tailored Metal Catalysts written by Y. Iwasawa and published by Springer Science & Business Media. This book was released on 1985-12-31 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Well tailored metal catalysts are catalysts of the new generation resulting from scientific development at the boundary between homogeneous and hetero­ geneous chemistry. The main factors involved in making tailored metal catalysts are not those of traditional impregnation in which the chemistry is in general unknown and ill-defined, or of simple ion exchange which involves long-range forces with little control on the local structure through definite and special bond direction. Tailored Metal Catalysts thus has a rather different emphasis from normal review publications in the field of catalysis. Here we concentrate more on the distinct surface chemistry and catalytic properties of important established materials with well-characterized active structures or precursors, although at the same time providing a systematic presentation of relevant data. Many pioneering works have been undertaken in the field of tailored metal catalysts since the early research on polymer-attached homogeneous metal complexes by the British Petroleum Company Ltd. and the Mobil Oil Corpora­ tion around 1969; transition metal complexes attached on polymers by Grubbs (1971), Heinemann (1971), Manassen (1971), Pittman (1971), Bursian et al. (1972), Kagan (1973), Bailar (1974); transition metal complexes attached on inorganic oxides by Allum et al. (1972), Ballard (1973), Candlin and Thomas (1974), Murrell (1974), Yermakov (1974); metal carbonyls/polymers by Moffat (1970); metal carbonyls/inorganic oxides by Parkyns (1965), Davie et al. (1969), Banks et al. (1969), Howe (1973), Burwell (1975); metal carbonyl clusters/ polymers by Colhnan (1972); metal carbonyl clusters/inorganic oxides by Robertson and Webb (1974), Anderson (1974), Smith et al. (1975).

Available in PDF, EPUB and Kindle. Book excerpt: This book aims to introduce the basic concepts involved in industrial catalytic processes. It is profusely illustrated with experimental results with the main objective of guiding how to select a suitable catalyst for specific processes. The book is divided in two parts. In the first part the basic concepts are addressed, regarding the existing theories, activity patterns and adsorption-desorption phenomena. In the second part the key experimental methods for the physicochemical characterization of catalysts are presented, as well as the currently used catalyst pre and post treatments. The last chapter describes some important in situ characterization techniques (e.g. XPS and TEM) and surface model patterns related to surface modifications occurring during the reaction. Thoroughly illustrated with microscopy images, spectroscopy data and schematics of reaction mechanisms, the book provides a powerful learning tool for students in undergraduate and graduate level courses on the field of catalysis. Exercises and resolved problems are provided, as well as experimental procedures to support laboratory classes. Furthermore, the content is presented in a carefully chosen sequence, reflecting the 30 year teaching experience of the author. The author, Professor Martin Schmal, sees the present book as a way of conveying basic knowledge needed for the development of more efficient catalysts (i.e. nanostructured materials) and novel industrial chemical processes in the fields of environmental chemistry, fine chemistry, hydrotreating of heavy oils, hydrogen production and biomass processing.

Download or read book New Aspects of Spillover Effect in Catalysis written by K. Fujimoto and published by Elsevier. This book was released on 1993-08-23 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: The spillover effect is one of the most promising factors in the enhancement of catalytic reaction rates. The spillover phenemenon was found in the 1960s by several research groups independently. It was defined at the previous International Symposium on Spillover as follows Spillover involves the transport of active species which are adsorbed or formed on a first phase onto another phase that does not adsorb or form the species under the same condition. However, this effect appears typically in the dynamic state, i.e., during reactions, which advance with a considerable reaction rate. This makes it difficult to elucidate the spillover effect through static methods. Therefore, more fundamental investigations are necessary. The development of alternative energy sources and protection of the environment demands highly selective and very rapid catalytic reactions at deviating conditions. To achieve these goals new concepts, such as the spillover effect, are needed. This proceedings book, which comprises 80 papers, contains methods for preparing catalysts in order to realize spillover effects and suggests the most probable mechanisms to explain these non-linear phenomena. It also contains studies on applications of the spillover effect to improve industrial catalytic processes. The book will be invaluable in the development of industrial catalysts and for solving energy and environmental protection problems.

Available in PDF, EPUB and Kindle. Book excerpt: Heterogeneous catalysts consisting of transition metal nanoparticles dispersed on high surface area oxide supports are ubiquitous in industrial-scale chemistry and alternative energy technology. Despite their importance, our fundamental understanding of the physical and chemical properties that make these systems catalytically effective is still incomplete. This dissertation details the use of surface-sensitive ultrahigh vacuum (UHV) techniques to study model catalysts consisting of late transition metals that are vapor-deposited onto single-crystal oxide films in order to understand how their fundamental physical and chemical properties affect their catalytic properties, such as activity, selectivity, and resistance to deactivation. Specifically, the binding energies of metal atoms and nanoparticles - and the adhesion energy of metal nanoparticles and films - are measured as a function of the size and type of nanoparticle, and the surface or site that they are adsorbed on. The key technique utilized in this study is single-crystal adsorption calorimetry (SCAC), which uses a highly sensitive detector to directly measure the heats of adsorption of metal vapor adsorbing onto oxide thin films. These calorimetric data are combined with surface-sensitive spectroscopic techniques to characterize the oxide surface, and to model the size of the nanoparticles a function of total metal coverage. This approach allows the heat data to be correlated with the surface structure, composition, particle size, or electronic character of the system. Several improvements to the instrument are discussed that allow for the study of metals with very low vapor pressures (high heats of vaporization), specifically Au, which is the focus of this work. This new instrument can also be operated at temperatures as low as 100 K, which is used to study metal atom adsorption under conditions where adatom diffusion is slower, which increases the particle density (reducing the size of particles formed) and increasing the likelihood that nucleation occurs at less favorable sites. Au adsorption is discussed here on three difference surfaces with increasing complexity: Pt(111), MgO(100), and CeO2-x(111). These results are compared to Cu adsorption on Pt(111) and CeO2-x(111) (also presented in this work), and to Cu adsorption on MgO(100) as well as Ag adsorption on MgO(100) and CeO2-x(111) (from previous work done by this research group). The first ever experimental measurements of gold adsorption onto an oxide surface as a function of particle size are presented, and the adsorption energy of both a single Au atom and a single Cu atom was measured on CeO1.95(111). This represents the first experimental measurements of any metal atom adsorption onto any oxide surface. The effect of defects on Au and Cu adsorption, such as step edges and electron-rich oxygen vacancies is discussed in detail. These defects are either introduced in film preparation (in the case of oxygen vacancies on CeO2-x(111)), or are inherently present in thin film preparations (morphological defects). The metals studied here, like most late transition metals, adsorb more strongly on morphological defects such as steps, while only Au and Ag bind more strongly to oxygen vacancies on CeO2-x(111) (Cu does not). Additionally, Au was found to nucleate significantly more strongly than Ag and Cu on morphological defects of MgO(100), and to form 2D islands on MgO(100) within the first 0.4 monolayers (ML) coverage. This work presents the first ever measurement of the heat of adsorption (and thus the chemical potential) of metal atoms in metal nanoparticles as a function of their 2D island diameter. A similar interpretation is used to present the chemical potential of Cu atoms in Cu nanoparticles as a function of their 3D particle dimeter on CeO2-x(111). The work contained in this dissertation has added critically important thermodynamic and structural data to the library of research in the catalysis and surface science communities, and has addressed some of the most relevant materials that could not be studied with previous generations of SCAC instruments. These model catalyst systems are of substantial fundamental and practice interest due to their immediate use in industrial catalysis, and combining these newest results with existing data (both from our group and from the literature) has allowed us to propose a new trend for metal-oxide adhesion. These investigations, and specifically this trend, will aid in the global effort to expedite the future design and testing process of new catalytic materials through improved understanding of their fundamental properties.
