Catalysis by Polymer-Immobilized Metal Complexes


Book Description

Deals with a new and promising field developed during the last two decades on the boundary between homogeneous and heterogeneous catalysis. This book presents general information on catalysis for a wide range of organic reactions, e.g., hydrogenation and oxidation reactions, and polymerization transformations. Special attention is paid to electro- and photochemical stimulation of catalytic processes in the presence of immobilized metal complexes. Other topics covered are the quantitative data on the comparison of catalyses by mobile and immobilized metal complexes; main factors affecting the activity of these catalytic systems and methods of optimizing their control; and specific problems of catalysis by fixed complexes (e.g., ligand exchange and electron transfer in metal polymer systems, macromolecular effects and polyfunctional catalysis).

Topic areas presented included several basic and applied topics in the field of advanced MMC such as preparation, characterization and fundamental aspects, macromolecules for advanced technologies including the sub-topics of electron- and ion conductors, separation, adsorption, transport of gas molecules, electronic-, magnetic-, photonic properties, catalysis and photocatalysis, liquid crystals, and biological-, medical- and environmental use.




Scientific Bases for the Preparation of Heterogeneous Catalysts


Book Description

It has become a tradition that every four years, the Université Catholique de Louvain and the Katholieke Universiteit Leuven jointly organize a symposium devoted to the scientific bases for the preparation of heterogeneous catalysts. These meetings bring together researchers from academia and industry and offer a forum for discussions on the chemistry involved in the preparation of industrial heterogeneous catalysts. This volume containing the Proceedings of the 8th International Symposium on Scientific Bases for the Preparation of Heterogeneous Catalysts consists of papers summarizing most of the 139 oral communications and posters selected by the international scientific committee, composed of 27 experts in the field of catalyst preparation, holding an industrial or academia appointment.The contributions focus on the aspects of catalyst preparation. The main topics are: new approaches in catalyst preparation; advanced preparations of nanoporous and mesoporous catalysts; catalysts preparation for special performances and purposes; catalysts for environmental purposes; and molecular catalysis. Emphasis is put on the role that catalysis can play as an essential element of sustainable development.




Transition Metals and Organometallics as Catalysts for Olefin Polymerization


Book Description

More than 30 years after the discovery of transition metals and organometal lics as catalysts for olefin polymerization these catalysts did not have lost their fascination. Since 1953 when Karl Ziegler has discovered the catalytic polymerization of ethylene leading to plastically formable polymers which are mechanically stable up to temperatures of about 100°C, synthetic polymers and rubbers have made their way right into private houses. This discovery has been a main impetus for the fast growing production of plastics. The stereoselective poly merization of propylene and other long-chain a-olefins first detected by Giulio Natta leads to an even broadened field of applications. Another enforcing factor were the developments of Standard Oil of Indiana and Phillipps Petroleum Company who engaged in the polymerization of a-olefins supported molybdenum, cobalt and later on chromium catalysts which clearly indicates the wide variety of suitable systems. This kind of research acknowledged merit when in 1963 the Nobel prize of chemistry was awarded to Ziegler and Natta. Although to a great extent there is a technical application for these catalysts, up to now the nature of the active centres and many reaction mechanisms are not completely known.

Metal Complexes and Metals in Macromolecules


Book Description

Metals and metal complexes can form compounds with organic macromolecules that show amazing properties. As is so often the case, nature leads by example. Synthetically produced model compounds, such as phthalocyanines, porphyrines or metalloproteins, as well as metallorganic polymers have aroused much interest in materials science. Their special magnetic, electrochemical and photochemical properties open up new perspectives in microelectronics and sensors. This compact manual is aimed at all organic, inorganic, polymer and physical chemists as well as materials scientists looking for competent and detailed information on the current state of this interdisciplinary area of research. It covers all questions relating to the targeted design of metallic macromolecules, from proven synthesis methods right up to the latest strategies. It also treats major progress in the determination of their structures, the physical-chemical properties of promising compounds and their potential in microelectronics and sensors. Furthermore, the most important methods of synthesis and investigation are presented in detail in an experimental section, while a comprehensive collection of pertinent original literature round s off this unique reference on all matters relating to macromolecular metal complexes.
