Heterogeneous catalysis is a core area of contemporary physical chemistry posing major fundamental and conceptual challenges. Catalysis lies at the heart of the chemical industry - an immensely successful and important part of the overall UK economy, and catalysis plays a crucial part in the production of 80% of all manufactured goods. Catalysis is a major theme in the chemical sciences and engineering that underlies much of the key research and teaching in these subjects. The reaction mechanisms of many commercial processes although successfully operated, are still a matter of debate and controversy, e.g. methanol synthesis and the Fischer-Tropsch process. Modern theoretical methods are now playing a central role in understanding reaction mechanisms and are starting to enable catalyst design. This volume brings together internationally leading researchers in this field to explore and exchange ideas concerning the key aspects of reaction mechanism studies and how this can drive the rational design of catalysts. In this volume, the topics covered include: Theory and reaction mechanisms Challenges of using advanced characterisation methods for in situ reaction mechanism studies Opportunities for understanding reaction mechanisms under flow conditions Dynamic catalytic systems on the border of heterogeneous/homogeneous catalysis
Heterogeneous catalysis plays a central role in the global energy paradigm, with practically all energy-related process relying on a catalyst at a certain point. The application of heterogeneous catalysts will be of paramount importance to achieve the transition towards low carbon and sustainable societies. This book provides an overview of the design, limitations and challenges of heterogeneous catalysts for energy applications. In an attempt to cover a broad spectrum of scenarios, the book considers traditional processes linked to fossil fuels such as reforming and hydrocracking, as well as catalysis for sustainable energy applications such as hydrogen production, photocatalysis, biomass upgrading and conversion of CO2 to clean fuels. Novel approaches in catalysts design are covered, including microchannel reactors and structured catalysts, catalytic membranes and ionic liquids. With contributions from leaders in the field, Heterogeneous Catalysis for Energy Applications will be an essential toolkit for chemists, physicists, chemical engineers and industrials working on energy.
Oxidation reactions are an important chemical transformation in both academia and industry. Among the major advances in the field has been the development of catalytic processes, which are not only selective and efficient, but also allow the replacement of common stoichiometric oxidants with molecular oxygen, ideally from air at atmospheric pressure. This results in processes with higher atom efficiency, where water is the only side product in line with the principles of green chemistry. Focusing on the use of molecular oxygen as the terminal oxidant, this book covers recent advances in both heterogeneous and homogeneous systems, with and without metals and on the "taming" of the highly reactive oxygen gas by use of micro-flow reactors and membranes. A useful reference for industrial and academic chemists working on oxidation processes, as well as green chemists.

This book discusses the ultrasonic synthesis, characterization and application of various nanoparticles, as well as the ultrasonic synthesis of metal and inorganic nanoparticles such as noble metals, transition metals, semiconductors, nanocomposites, alloys and catalysts. In addition, it describes the engineering of micro- and nanosystems using ultrasound-responsive biomolecules. In acoustic cavitation, unique phenomena based on bubbles dynamics, extreme high-temperature and pressure conditions, radical reactions, extreme heating and cooling rates, strong shockwaves, and microstreaming are generated, and under certain conditions, mist generation (atomization of a liquid) is effectively induced by ultrasonic irradiation. These unique phenomena can be used to produce various high-performance functional metal and inorganic nanoparticles. Nanoparticles and nanomaterials are key materials in advancing nanotechnology and as such ultrasound and sonochemical techniques for producing nanoparticles and nanomaterials have been actively studied for the last two decades. Although a few professional books related to "ultrasound" and "nanomaterials" have been published, these mainly target professional researchers. This book covers this topic in a way that appeals to graduate students, researchers and engineers.

Hydrogenation is a key reaction in both the food and petrochemical industries, where it is used to reduce carbon-carbon double bonds. Without a catalyst, hydrogenation reactions require extreme temperatures to occur, meaning catalysts are essential for the reaction to be industrially useful. During the past decade, the properties of many carbon nanomaterials that are relevant to hydrogenation catalysis have been described, including carbon nanotubes (CNTs), carbon nanofibers (CNFs), carbon nanohorns (CNHs), graphene oxide (GO), reduced graphene oxides (rGO) and fullerenes, that are relevant to hydrogenation catalysis, have been described. For many of these the production methods have advanced to the commercial stage. Numerous studies on the development of catalysts on carbon nano-supports have appeared in the scientific literature and these catalysts have shown remarkable activity and specificity. Carbon Nanomaterials in Hydrogenation Catalysis is a valuable reference for researchers and chemical engineers working on improving hydrogenation processes and those interested in applications for carbon nanomaterials. Covering their production, modification and applications as a catalyst support this book provides an in-depth review of the current state-of-the art in using carbon nanomaterials for hydrogenation reactions.
Vehicle exhaust emissions, particularly from diesel cars, are considered to be a significant problem for the environment and human health. Lean NOx Trap (LNT) or NOx Storage/Reduction (NSR) technology is one of the current techniques used in the abatement of NOx from lean exhausts. Researchers are constantly searching for new inexpensive catalysts with high efficiency at low temperatures and negligible fuel penalties, to meet the challenges of this field. This book will be the first to comprehensively present the current research on this important area. Covering the technology used, from its development in the early 1990s up to the current state-of-the-art technologies and new legislation.

Most chemical reactions in industry and biology are catalytic and play a role at some stage of the processing of about 80% of the goods manufactured in the U.S., yet catalysis is a neglected subject in chemical education. The fragmentary treatment accorded the topic until now is integrated. It covers, in a unified way, catalysis in solutions, by enzymes, in synthetic polymers within the molecular scale cages of zeolites and other molecular sieves, and on surfaces of inorganic solids. The central ideas are chemical; principles are illustrated by emphasizing industrial reactions and catalysts.
An outstanding international scientific event in the field of metathesis chemistry, the NATO ASI "Green Metathesis Chemistry: Great Challenges in Synthesis, Catalysis and Nanotechnology" has been recently organized in Bucharest, Romania (July 21- August 2, 2008). Numerous renowned scientists, young researchers and students, convened for two weeks to present and debate on the newest trends in alkene metathesis and identify future perspectives in this fascinating area of organic, organometallic, catalysis and polymer chemistry with foreseen important applications in materials science and technology. Following the fruitful practice of NATO Advanced Study Institutes, selected contributions covering plenary lectures, short communications and posters have been compiled in this special volume dedicated to this successful convention on green metathesis chemistry. General interest was primarily focused on relevant "green chemistry" features related to all types of metathesis reactions (RCM, CM, enyne metathesis, ADMET and ROMP). Diverse opportunities for green and sustainable technologies and industrial procedures based on metahesis have been identified. Largely exemplified was the utility of this broadly applicable strategy in organic synthesis, for accessing natural products and pharmaceuticals, and also its ability to fit in the manufacture of smart and nanostructured materials, self-assemblies with nanoscale morphologies, macromolecular engineering.
Noncovalent interactions often provide the spine of biomolecular and material structures, and can therefore play a key role in biological and catalytic processes. Selectivity in chemical reactions, particularly in catalytic processes, is often an orchestral action of various noncovalent interactions occurring in intermediates and transition states. Although the role of hydrogen bonding is well explored in catalysis, the other types of weak interactions, namely cation- , anion- , - stacking, pseudo-agostic, halogen, chalcogen, pnictogen, tetrel and icosagen bonds, must also be considered. Naturally, the chemo-, regio- or stereoselectivity of a reaction depends on the stability of such noncovalent-interaction-supported species in catalytic systems. Therefore, an in-depth understanding of these weak interactions may be the key to designing new catalytic materials. Providing an overview of the role of these different types of noncovalent interactions in both homogenous and heterogeneous catalysis, this book is a valuable resource for synthetic chemists who are interested in exploring and further developing noncovalent-interaction-assisted synthesis and catalysis.
Heterogeneous catalysis has developed over the past two centuries as a technology driven by the needs of society, and is part of Nobel Prize-winning science. This book describes the spectacular increase in molecular understanding of heterogenous catalytic reactions in important industrial processes. Reaction mechanism and kinetics are discussed with a unique focus on their relation with the inorganic chemistry of the catalyst material. An introductory chapter presents the development of catalysis science and catalyst discovery from a historical perspective. Five chapters that form the thrust of the book are organized by type of reaction, reactivity principles, and mechanistic theories, which provide the scientific basis to structure-function relationships of catalyst performance. Present-day challenges to catalysis are sketched in a final chapter. Written by one of the world's leading experts on the topic, this definitive text is an essential reference for students, researchers and engineers working in this multibillion-dollar field.
Conversion of light and electricity to chemicals is an important component of a sustainable energy system. The exponential growth in renewable energy generation implies that there will be strong market pull for chemical energy storage technology in the near future, and here carbon dioxide utilization must play a central role. The electrochemical conversion of carbon dioxide is key in achieving these goals. Carbon Dioxide Electrochemistry showcases different advances in the field, and bridges the two worlds of homogeneous and heterogeneous catalysis that are often perceived as in competition in research. Chapters cover homogeneous and heterogeneous electrochemical reduction of CO2, nanostructures for CO2 reduction, hybrid systems for CO2 conversion, electrochemical reactors, theoretical approaches to catalytic reduction of CO2, and photoelectrodes for electrochemical conversion. With internationally well-known editors and authors, this book will appeal to graduate students and researchers in energy, catalysis, chemical engineering and chemistry who work on carbon dioxide.
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.
In recent years polymerisation using organocatalysts has become an appealing alternative to more traditional metal-based catalysts. Conferring numerous advantages including low cost and ease of use, as well as the ability to precisely control the synthesis of advanced polymer structures, organocatalysts are increasingly used in polymer synthesis. Organic Catalysis for Polymerisation provides a holistic overview of the field, covering all process in the polymer synthesis pathway that are catalysed by organic catalysts. Sub-divided into two key sections for ease of use, the first focuses on recent developments in catalysis and the applications of catalysts to the full range of polymerisations that they have been utilised in; the second concerning monomers, arranges the field by monomer type and polymerisation mechanism. The book will therefore, provide a complimentary view of the field, providing both an overview of state-of-the-art catalyst development and also the best methodologies available to create specific polymer types. Edited by leading figures in the field and featuring contributions from researchers across the globe, this title will serve as an excellent reference for postgraduate students and researchers in both academia and industry interested in polymer chemistry, organic chemistry, catalysis and materials science.
Die Bedeutung des katalytischen Moments im chemischen Geschehen riickt in neuerer Zeit immer mehr in den Vordergrund des Interesses, angeregt besonders durch die Entwicklung der Technik von der einen, der wissenschaftlichen Biologie von der anderen Seite her. Mit dem damit zunehmenden Bediirfnis nach einer wissenschaftlichen Behandlung der Katalyse hat die Ausbildung der notwendigen Grundlagen der physi kalischen Chemie im allgemeinen Schritt gehalten. Insbesondere die chemische Kinetik bildet schon auf dem heutigen Stande ihrer rasch fortschreitenden Entwicklung einen recht tragfahigen Unterbau. Zwar tauchen gerade jetzt in vermehrter Zahl hinter den gelOsten alten die vertieften neuen Probleme auf, aber eben deshalb scheint ein Versuch lohnend, die Katalyse yom Standpunkt der chemischen Kinetik zu sammenfassend a bzuhandeln. Es hatte hierbei weder dem verfiigbaren Spielraum in Zeit und Raum, noch wohl einem Bediirfnis entsprochen, eine irgendwie umfassende oder gar erschopfende Sammlung des Tatsachenmaterials in seiner erdriicken den Fiille zu geben. Ebensowenig sollen etwa aIle alteren und neueren Deutungsversuche und Theorien katalytischer Erscheinungen refe rierend wiedergegeben werden. Es wurde vielmehr der Plan verfolgt, die fiir die Katalyse iiberhaupt und ihre verschiedenen Abarten gelten den GesetzmaBigkeiten herauszuarbeiten und an ihnen die Prinzipien und Mechanismen zu erlautern und zu erharten, nach denen katalytische Geschwindigkeitsbeeinflussungen moglich sind und vor sich gehen."
This book focuses on the use of bio-inspired and biomimetic methods for the fabrication and activation of nanomaterials. This includes studies concerning the binding of the biomolecules to the surface of inorganic structures, structure/function relationships of the final materials and extensive discussions on the final applications of such biomimetic materials in unique applications including energy harvesting/storage, biomedical diagnostics and materials assembly.
Many important industrial chemical processes rely heavily on catalysis and so researchers are always on the lookout for alternative catalytic materials that may improve existing processes or lead to new ones. Families of alternative catalytic materials currently being investigated include the carbides, nitrides and phosphides as well as amorphous boron catalysts. The addition of carbon, nitrogen or phosphorous to transition metals and the creation of boron-transition metal alloys leads to catalytic materials that have interesting properties, with applications in a range of different reactions, including electrocatalysis. This book provides a comprehensive account of the preparation, characterisation and application of these catalytic materials. It is an important reference for researchers and industrialists working in heterogeneous catalysis and materials chemistry. |
