The book describes the valorization of biomass-derived compounds over gold catalysts. Since biomass is a rich renewable feedstock for diverse platform molecules, including those currently derived from petroleum, the interest in various transformation routes has become intense. Catalytic conversion of biomass is one of the main approaches to improving the economic viability of biorefineries. In addition, Gold catalysts were found to have outstanding activity and selectivity in many key reactions. This book collects information about transformations of the most promising and important compounds derived from cellulose, hemicelluloses, and woody biomass extractives. Since gold catalysts possess high stability under oxidative conditions, selective oxidation reactions were discussed more thoroughly than other critical reactions such as partial hydrogenation, acetalization, and isomerization. The influence of reaction conditions, the role of the catalyst, and the advantages and disadvantages of using gold are presented for all of the reactions mentioned above. This book provides an overview of the recent research results focusing on application of gold catalysts for synthesis of valuable chemicals using renewable feedstocks.
This book highlights key advances that have occurred in the field of olefin conversion in recent years.

In this volume, Professor He and his coworkers summarize polyethylene glycol (PEG)-promoted CO2 chemistry on the basis of understanding about phase behavior of PEG/CO2 system and reaction mechanism at molecular level. As PEG could be utilized as a green replacement for organic solvents, phase-transfer catalyst, surfactant, support in various reaction systems, significantly promoting catalytic activity and recovering expensive metal catalysts, particularly regarded as a CO2-philic material, the authors focus on special applications of PEG in CO2 capture and utilization, including PEG-functionalized catalysts for efficient transformation of CO2 and PEG-functionalized absorbents for efficient CO2 capture. Furthermore, they describe carbon capture and utilization strategy as an alternative approach to address the energy penalty problem in carbon capture and storage. Interestingly, the authors also discuss PEG radical chemistry in dense CO2 as rather creative and unusual use of PEG, presumably serves as a reaction medium and a radical initiator for radical chemistry.
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.
Even though Ziegler catalysts have been known for almost half a century, rare earth metals (Ln), particularly neodymium (Nd)-based Ziegler catalyst systems, only came into the focus of industrial and academic research well afterthelargescaleapplicationoftitanium, cobaltandnickelcatalystsystems. Asadirectconsequenceofthelaterecognitionofthetechnologicalpotentialof rareearthmetalZieglercatalysts, thesesystemshaveattractedmuchattention. Considerable progress has been made in this ?eld as a result of intensive workperformed during the last fewyears. Worthmentioning is thestructural identi?cation of a variety of Ln/Al heterobimetallic complexes and the role of alkyl aluminum cocatalysts in molar mass control. Furthermore, a deeper understanding ofthe polymerization mechanism, suchas theliving character of neodymium-catalyzed diene polymerization associated with the reversible transfer of living polymer chains between Nd and Al, was revealed quite - cently. In spite of the vast number of patents and publications mainly issued duringthelastdecade, acomprehensivereviewthatcoversthescienti?caswell as the patent literature has been missing until now. In this volume we try to review the available literature by two independent approaches to Nd and Ln-catalyzed diene polymerizations. In the ?rst part of thevolume, whichisentitled"Neodymium-Based Ziegler/NattaCatalystsand their Application in Diene Polymerization," a polymer chemist's view is given with strong emphasis on Nd-based catalyst systems. Also technological and industrialaspectsofNd-catalyzeddienepolymerizationsareaddressed.Inthe secondpartofthevolume, whichisentitled"Rare-EarthMetalsandAluminum Getting Close in Ziegler-type Organometallics," a more organometallic p- spective isgivenandLn-based catalystsystems areaddressed. Bythesynopsis of these different perspectives, the reader will comprehend the complexity of Ln-based Ziegler catalyst systems and their application to the polymerization of dienes. This volume also gives a description ofthe evolution in Nd-catalyzed po- merization of dienes from the early works to the current state of the art.

For fifty years, Hydrosilylation has been one of the most fundamental and elegant methods for the laboratory and industrial synthesis of organosilicon and silicon related compounds. Despite the intensive research and continued interest generated by organosilicon compounds, no comprehensive book incorporating its various aspects has been published this century. The aim of this book is to comprehensively review the advances of hydrosilylation processes since 1990. The survey of the literature published over the last two decades enables the authors to discuss the most recent aspects of hydrosilylation advances (catalytic and synthetic) and to elucidate the reaction mechanism for the given catalyst used and the reaction utilization. New catalytic pathways under optimum conditions necessary for efficient synthesis of organosilicon compounds are presented. This monograph shows the extensive development in the application of hydrosilylation in organic and asymmetric syntheses and in polymer and material science.

Heterogeneous catalysis has been essential to the development of efficient chemical processes for more than a century, and this field has been traditionally part of the solid state chemistry and surface science communities. The design of better catalysts has raised the following questions: "what is the structure of the active sites?" and "how to control their nature?" The necessary need to develop more sustainable chemical processes and the success of homogeneous catalysis relying on molecular organometallic chemistry has led the community of molecular chemists to investigate the preparation of single-site heterogeneous catalysts. The authors discuss the molecular design, the preparation, the characterisation and the catalytic applications of well-defined oxides and metal particles. The readers will acquire a molecular understanding of heterogeneous catalysis, which will help them develop a critical view and which will attract them to study this fascinating field.
Modern organic synthesis has paid much attention to the chemistry of small carbocycles. Vinylidenecyclopropanes (VDCPs), which have strained cyclopropyl group connected with an allene moiety and yet are thermally stable and reactive substances in organic chemistry, are versatile intermediates in organic synthesis. In this volume, Dr. Lixiong Shao, Dr. Jianmei Lu and Prof. Dr. Min Shi review their investigations on the chemistry of VDCPs, mainly including the preparation, the reactivities upon treatment with Lewis or Bronsted acid, as well as transition metal catalysts and some other miscellaneous analogues. The contributions aroused a renaissance of cationic intermediates in the chemistry of VDCPs.
Control over macromolecular architecture and resulting material properties has been a central goal of polymer chemistry. There has been much interest in developing new synthetic routes to prepare smart materials with novel compositions and topologies for various applications. The considerable progress in the metal mediated macromolecular engineering over the past decade has had a major impact on the development of well-defined macromolecular architectures and the synthesis of smart materials. Particularly, remarkable strong developments have been observed for the synthesis of smart materials via four metal mediated macromolecular engineering techniques; Anionic, ROMP, ATRP and Click Chemistry. These materials have found uses in advanced microelectronics, technical and biomedical applications as well as in chemical sensors applications. This book is comprised of 27 chapters written by leading scientists from NATO and Partner Countries who have greatly contributed in the area of Anionic, ROMP, ATRP and Click Chemistry. It highlights the fundamental aspects and recent developments of these four powerful techniques and evaluate their potential in the syntheses of smart materials from complex structures (grafts, brushes, dendrimers, etc.) to nanostructures (self-assembly, nano-size, etc) for a wide range of applications. The book reports on the synthesis of a wide range of well-defined complex polymeric systems such as thermoresponsive smart polymers, star copolymers, biocompatible polymers, amphipilic smart nano structured, conducting polymers, self assembled polymers, and hyperbranced polymers.
Analytical chemical results touch everyones lives can we eat the food? do I have a disease? did the defendant leave his DNA at the crime scene? should I invest in that gold mine? When a chemist measures something how do we know that the result is appropriate? What is fit for purpose in the context of analytical chemistry? Many manufacturing and service companies have embraced traditional statistical approaches to quality assurance, and these have been adopted by analytical chemistry laboratories. However the right chemical answer is never known, so there is not a direct parallel with the manufacture of ball bearings which can be measured and assessed. The customer of the analytical services relies on the quality assurance and quality control procedures adopted by the laboratory. It is the totality of the QA effort, perhaps first brought together in this text, that gives the customer confidence in the result. QA in the Analytical Chemistry Laboratory takes the reader through all aspects of QA, from the statistical basics and quality control tools to becoming accredited to international standards. The latest understanding of concepts such as measurement uncertainty and metrological traceability are explained for a working chemist or her client. How to design experiments to optimize an analytical process is included, together with the necessary statistics to analyze the results. All numerical manipulation and examples are given as Microsoft Excel spreadsheets that can be implemented on any personal computer. Different kinds of interlaboratory studies are explained, and how a laboratory is judged in proficiency testing schemes is described. Accreditation to ISO 17025 or OECD GLP is nearly obligatory for laboratories of any pretension to quality. Here the reader will find an introduction to the requirements and philosophy of accreditation. Whether completing a degree course in chemistry or working in a busy analytical laboratory, this book is a single source for an introduction into quality assurance.
The study of environmental interfaces and environmental catalysis is central to finding more effective solutions to air pollution and in understanding of how pollution impacts the natural environment. Encompassing concepts, techniques, and methods, Environmental Catalysis provides a mix of theory, computation, analysis, and synthesis to support the latest applications in biocatalysis, green chemistry, environmental remediation and our understanding of the interaction of pollutants with natural systems. The book focuses on several aspects of environmental catalysis. Surface catalysis of airborne particles - including ice, trace atmospheric gases, aerosolized soot nanoparticles, and mineral dust surfaces - as well as particles in contact with ground water and their role in surface adsorption, surface catalysis, hydrolysis, dissolution, precipitation, oxidation and ozone decomposition is explored. It continues by presenting catalysis as the key technology for treating emissions and reducing waste by-products. The authors review the theory behind catalytic converters and discuss the effectiveness of several catalysts, including zeolites and nanoparticles, in treating emissions, aromatic hydrocarbons, and chemical warfare agents. They also survey the use of biocatalysis in environmental remediation, and industrial processes, particularly in the production of transportation fuels, fine chemicals, and pharmaceuticals. Then the authors explain how enzymes can remove chlorinated organics and metals and how microbes can metabolize toxic chemicals from groundwater. Lastly, they discuss the principles of green chemistry, including the use of environmentally benign solvents, biphasic catalysts, and other alternative solvents to recover and recycle catalysts based on heavy metals. With increasing ground water pollution, increasing particulates in the atmosphere, and the increasing need to remove pollutants from industrial and automotive sources, Environmental Catal
The focus of the book is on the fundamental concepts that are needed to understand how solid surfaces act as catalysts. The aim is not to give a complete overview of types of catalysts or catalytic processes or to give a detailed introduction to the experimental and computational methods that are used to study them. A number of recent textbooks cover these areas very well; see the "further reading" list at the end of the chapter. We will use a number of simple catalytic processes as examples throughout, but only in order to develop the general rules according to which heterogeneous catalysis works. Chapters include: The Potential Energy Diagram; Surface Equilibria; RateConstants; Energy Trends in Catalysis; The Electron Factor in Heterogeneous Catalysis; Catalyst Structure: The Nature of the Active Site; Poisoning and Promotion of Catalysis; Surface Electrocatalysis; and Relation of Activity toSurface Electronic Structure
Catalysis is a multidisciplinary subject. This book introduces the chemical, materials, and engineering principles of catalysis so that both MSc and PhD students with a basic but not extensive knowledge of chemistry and physics and those with a basic understanding of chemical engineering can learn more about catalysis. Examples are taken from catalytic reactions and catalysts used in the energy, petroleum, and base-chemicals industry.The second edition differs from the first edition in the way basic topics are integrated with catalytic applications. The authors introduce two new chapters: 'Cleaning of Fuels by Hydrotreating' and 'Electrocatalysis'. Hydrotreating is a very important industrial process and offers the opportunity to discuss metal sulfide catalysts. Electrocatalysis gains more and more attention because it can be used to minimize the anthropogenic CO2 emissions. Solar, wind, and hydroelectricity can drive water electrolysis and CO2 electroreduction and, therefore, excess renewable electricity can be stored in chemicals.Introduction to Heterogeneous Catalysis (Second Edition) is intended for a one-semester course for master and PhD students who want to learn more about the principles of catalysis. This must-read textbook will enable students to read catalysis literature without much difficulty and presents not only the basic concepts of catalysis but integrates the chemical, materials, and engineering aspects of catalysis with industry examples.
There are many mononuclear iron containing enzymes in nature that utilize molecular oxygen and transfer one or both oxygen atoms of O2 to substrates. These enzymes catalyze many processes including the biosynthesis of hormones, the metabolism of drugs, DNA and RNA base repair and, the biosynthesis of antibiotics. Therefore, mononuclear iron containing enzymes are important intermediates in bioprocesses and have great potential in the commercial biosynthesis of specific products since they often catalyze reactions regioselectively or stereospecifically. Understanding their mechanism and function is important and will assist in searches for commercial exploitation. In recent years, advances in experimental as well as theoretical methodologies have made it possible to study the mechanism and function of these enzymes and much information on their properties has been gained. This book highlighting recent developments in the field is, therefore, a timely addition to the literature and will interest a broad readership in the fields of biochemistry, inorganic chemistry and computational chemistry. The Editors, leaders in the field of nonheme and heme iron containing monoxygenases, have filled the book with topical review chapters by leaders in the various sub-disciplines.
Implementing biocatalytic strategies in an industrial setting at a commercial scale is a challenging task, necessitating a balance between industrial need against economic viability. With invited contributions from small and large-scale chemical and pharmaceutical companies, this book bridges the gap between academia and industry. Contributors discuss current processes, types of biocatalysts and improvements, industrial motivation and key aspects to economically succeed. With its focus on industry related issues, this book will be a useful tool for future research by both practitioners and academics.
This volume covers recent advances in the chemistry of ylidic compounds with focus on their application in the design of ligands with unique donor properties, the development of novel organic transformations as well as the use of ylides in homogenous catalysis. Thereby, this volume particularly aims at the community of organic and organometallic chemists engaged in synthetic chemistry and catalysis as well as in the use of special ligands for the stabilization of unusual main group element species and the "transition-metal free" activation of element-element/hydrogen bonds. These fields of research are highly active and vivid research areas to which ylide chemistry has only recently started to contribute, but has already led to fascinating developments in most different directions. This volume highlights these recent developments, thus giving not only an overview over the past achievements, but also possibilities for future applications. To this end, the chapters selected in this volume combine different aspects of ylide chemistry, starting with theoretical aspects in ligand design followed by synthetic organic methods, catalytic transformations and complex chemistry.
This book describes innovative techniques to study catalysts and reaction mechanisms, helping chemists improve the performance of their reactions and the efficiency (through reduced materials and waste) of catalyst preparation. It explains both the scope and limitations of specific techniques, including the characterization of the electronic and structural properties of catalysts using XAFS (X-ray Absorption Fine Structure Spectroscopy); techniques for structural characterization based on X-ray diffraction and scattering; for microscopy and morphological studies; for studying the interaction of adsorbates with catalyst surfaces (Raman spectroscopy, NMR, moderate pressure XPS); and mixed techniques. |
