With contributions from experts in supported metal catalysis, from both the industry and academia, this book presents the latest developments in characterization and application of supported metals in heterogeneous catalysis. In addition to a thorough and updated coverage of the traditional aspects of heterogeneous catalysis such as preparation, characterization and use in well-established technologies such as Naphtha reforming, the book also includes emerging areas where supported metal catalysis will make significant contributions in future developments, such as fuel cells and fine chemicals synthesis. The second edition of Supported Metals in Catalysis comes complete with new and updated chapters containing important summaries of research in a rapidly evolving field. Very few other books deal with this highly pertinent subject matter, and as such, it is a must-have for anyone working in the field of heterogeneous catalysis.

This text explores the optimization of catalytic materials through traditional and novel methods of catalyst preparation, characterization, and monitoring for oxides, supported metals, zeolites, and heteropolyacids. It focuses on the synthesis of bulk materials and of heterogeneous materials, particularly at the nanoscale. The final chapters examine pretreatment, drying, finishing effects, and future applications involving catalyst preparation and the technological advances necessary for continued progress. Topics also include heat and mass transfer limitations, computation methods for predicting properties, and catalyst monitoring on laboratory and industrial scales.

The proceedings of the VIIth International Symposium on the Scientific Bases for the Preparation of Heterogeneous Catalysts, are in line with the general scope of this series of events. Emphasis in all Symposia has been on the scientific aspects of the preparation of new and industrial catalysts, or on new methods of preparation, rather than on the catalytic reactions in which such solids are ultimately used. In the present context, the catalytic event itself has only been considered as another, though often decisive, method of catalyst characterization.

Nanocatalysis is a topical area of research that has huge potential. It attempts to merge the advantages of heterogeneous and homogeneous catalysis. The collection of articles in this book treats the topics of specificity, activity, reusability, and stability of the catalyst and presents a compilation of articles that focuses on different aspects of these issues.

For the many chemical industrial processes which require highly selective transformations, homogeneous catalysts are paramount. The effectiveness of molecular organometallic catalysts in particular can be largely attributed to the precise tools available for synthesis and characterization of the ligands and metal complexes, which allow for fine control over electronics and sterics to optimize substrate binding, reaction kinetics, and catalyst stability. Platinum group metals (PGMs; Ru, Os, Rh, Ir, Pd, Pt) enjoy special distinction among transition metal catalysts `for their high selectivity and activity for a number of reactions of interest such as cross-coupling, oligomerization, and hydrofunctionalization. Such homogeneous catalysts still find widespread application at the industrial scale, but the steep cost of these metals places stringent requirements on homogeneous systems for metal recovery. Heterogenization of PGMs thus poses a substantial benefit by enabling efficient catalyst reuse, but it remains a challenge to translate the well-defined nature of molecular catalysts (and thus their high selectivity/activity) to a solid support. In this thesis, I describe the development of methodologies for producing well-defined single-site PGM catalysts on a solid support using metal-organic frameworks (MOFs). MOFs are attractive platforms for the heterogenization of PGM catalysts because, in addition to high porosity and crystallinity, MOFs are structurally tunable at the molecular level, allowing fine synthetic control over active sites and their local environments. Chapter 2 of this thesis describes the development of complementary methodologies for generating well-defined PGM scorpionates on a MOF composed of Tpm-based linkers. Detailed structural studies of Pd(II) installed in the C3[subscript v] scorpionate sites reveals an unusually Pd(II)-N[subscript apical] interaction between the bidentate Pd complex and the third uncoordinated pyrazole arm of the ligand (Pd-N[subscript apical] = 2.501 ± 0.067 Å). Chapter 3 describes a new synthetic strategy, termed "tetrazine click-grafting", which enables facile post-synthetic installation of phosphorus ligands onto MOFs. Lastly, Chapter 4 reports the catalysis of MOF-supported Rh phosphines prepared via tetrazine click-grafting for the hydroformylation of vinylsilanes and simple alkenes, with remarkable selectivity for linear aldehydes.

Discusses recent research and provides tutorial chapters on enhancing selectivity in catalysis through stereoselectivity, reaction pathway control, shape selectivity, and alloys and clusters. Presents an interdisciplinary approach to increasing selectivity in homogeneous and heterogeneous catalysis research. Includes an overview chapter that discusses the current state of the field and offers a perspective on future directions.

Catalysis is the acceleration of a chemical reaction by a catalyst, a substance that notably affects the rate of a chemical reaction without itself being consumed or altered. Since 1948, Advances in Catalysis has filled the gap between the papers that report on and the textbooks that teach in the diverse areas of catalysis research. The editors of and contributors to Advances in Catalysis are dedicated to recording progress in this area.* Provides a comprehensive review of all aspects of catalytic research * Contains in-depth, critical, state-of-the-art reports

This book describes a science and technology of a new type of electrocatalysts consisting of a single atomic layer of platinum on suitable supports. This development helped overcome three major obstacles—catalysts‘ cost, activity, and stability—for a broad range of fuel cell applications. The volume begins with a short introduction to the science of electrocatalysis, covering four reactions important for energy conversion in fuel cells. A description follows of the properties of metal monolayers on electrode surfaces, and underpotential deposition of metals. The authors then describe the concept of Pt monolayer electrocatalysts and its implications and their synthesis by galvanic displacement of less-noble metal monolayers and other methods. The main part of the book presents a discussion of catalysts’ characterization and catalytic properties of Pt monolayers for the four main reactions of electrochemical energy conversion: oxygen reduction and oxidation of hydrogen, methanol and ethanol. The book concludes with a treatment of scale-up syntheses, fuel cell tests, catalysts’ stability and application prospects.
