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

The chemistry of metal oxides, both single and mixed metal oxides, relevant to heterogeneous catalysis such as relationships among the composition, structure, and chemical properties of mixed oxides, is provided in perspective. The important chemical properties in heterogeneous catalysis are acid–base and reduction–oxidation (redox) properties, where ionic radii, electronegativity, valency, and tendency to form covalent bond of constituent elements are most influential. Structural factors such as lattice defects and nonstoichiometry are also relevant. Although the surface of metal

Several substantial examples of mixed oxide supports that show unique and interesting roles as catalyst supports are described. The examples are perovskites and heteropoly compounds as supports for finely dispersed metals, ceria–zirconia related mixed oxides as supports for noble metals in automobile catalysts, and zeolites for atomically dispersed noble metals. In addition, the general roles of catalyst supports are briefly summarized. Among the different roles of supports, the most important are dispersing the catalytically active components and increasing their

The chemistry and catalysis of perovskites are described. “Perovskites” are defined here as double oxides having perovskite (ABO3) and related structures. Double oxides are one of the two major groups of mixed oxides. Because of their thermal stability and a variety of physical and chemical properties, which can be controlled by choosing constituent elements, they are widely used as catalysts as well as electronic and magnetic materials. First, an overview is given of the structural characteristics of perovskites, including lattice

A concise introduction is given to the fundamental knowledge required to understand the heterogeneous catalysis of mixed oxides and to the concept of catalyst design. The fundamental knowledge includes the rate versus equilibrium relation; rate equation; the mechanism of catalytic reaction; essential functions of a catalyst, namely, activity, selectivity, and durability (or life); and catalytic reaction engineering such as mass and heat transfer. Typical methods for the preparation and characterization of catalysts and for the elucidation of the reaction mechanism,

The chemistry and catalysis of solid heteropoly compounds are described. Heteropoly compounds are heteropolyanions and their derivatives that maintain the polyanion structure (metal oxide clusters), and catalysts of which the compounds are the essential components are called heteropoly catalyst. Heteropoly compounds are called polyoxometalates as well. First, the structure and chemical properties of heteropoly compounds are summarized, emphasizing the acidic and redox properties. The polyanion structure can be preserved in the solid state, if appropriate cautions are paid, and the

This book presents current research into the catalytic combustion of methane using perovskite-type oxides (ABO3). Catalytic combustion has been developed as a method of promoting efficient combustion with minimum pollutant formation as compared to conventional catalytic combustion. Recent theoretical and experimental studies have recommended that noble metals supported on (ABO3) with well-ordered porous networks show promising redox properties. Three-dimensionally ordered macroporous (3DOM) materials with interpenetrated and regular mesoporous systems have recently triggered enormous research activity due to their high surface

Mixed-metal oxides exhibit novel properties that are not present in their isolated constituent metal oxides and play a significant role in heterogeneous catalysis. In this study, a titanium-copper mixed-oxide (TiCuOx) film has been synthesized on Cu(111) and characterized by complementary experimental and theoretical methods. At sub-monolayer coverages of titanium, a Cu2O-like phase coexists with TiCuOx and TiOx domains. When the mixed-oxide surface is exposed at elevated temperatures (600-650 K) to oxygen, the formation of a well-ordered TiCuOx film occurs.

Mixed metal oxides have attracted considerable attention in heterogeneous catalysis due to the unique stability, reactivity, and selectivity. Here, the activity and stability of the CuTiOx monolayer film supported on Cu(111), CuTiOx/Cu(111), during CO oxidation was explored using density functional theory (DFT). The unique structural frame of CuTiOx is able to stabilize and isolate a single Cu+ site on the terrace, which is previously proposed active for CO oxidation. Furthermore, it is not the case, where the reaction via

Kinetics and reactor modeling for heterogeneous catalytic reactions are prominent tools for investigating and understanding catalyst functionalities at nanoscale and the related rates of complex reaction networks. This book illustrates some examples related to the transformation of simple to more complex feedstocks, including different types of reactor designs, i.e., steady-state, transient plug flow reactors, and TAP reactors for which there is sometimes a strong gap in the operating conditions from ultra-high-vacuum to high-pressure conditions. In conjunction, new methodologies have
