Solid-State NMR in Zeolite Catalysis


Book Description

Solid-State NMR Characterization of Heterogeneous Catalysts and Catalytic Reactions provides a comprehensive account of state-of-the-art solid-state NMR techniques and the application of these techniques in heterogeneous catalysts and related catalytic reactions. It includes an introduction to the basic theory of solid-state NMR and various frequently used techniques. Special emphasis is placed on characterizing the framework and pore structure, active site, guest-host interaction, and synthesis mechanisms of heterogeneous catalysts using multinuclear one- and two-dimensional solid-sate NMR spectroscopy. Additionally, various in-situ solid-state NMR techniques and their applications in investigation of the mechanism of industrially important catalytic reactions are also discussed. Both the fundamentals and the latest research results are covered, making the book suitable as a reference guide for both experienced researchers in and newcomers to this field. Feng Deng is a Professor at Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences.




NMR Techniques in Catalysis


Book Description

This volume provides an overview of the applications of modern solid-state nuclear magnetic resonance (NMR) techniques to the study of catalysts, catalytic processes, species adsorbed on catalysts and systems relevant to heterogeneous catalysis. It characterizes the structure of catalytic materials and surfaces.







Mechanisms in Homogeneous Catalysis


Book Description

While chemists using spectroscopic methods need to learn from the specialists, they do not normally read the spectroscopists' original papers. This book provides this very information -- summarizing some recent advances in the mechanistic understanding of metallocene polymerization catalysts and the role of NMR spectroscopy in these endeavors. Adopting a real practice-oriented approach, the authors focus on two of the most important spectroscopic techniques with two parts devoted to each of NMR and IR spectroscopy - as well as on important industrial applications with regard to the reaction discussed. Rather than providing a complete and exhaustive review of homogeneous hydrogenation and its detailed mechanisms, the book focuses on the specific spectroscopic techniques and the mechanistic information that has been obtained from their application. The result is unique in its scope, allowing chemists from different fields to learn which techniques can be applied for their specific synthetic problems. The prizewinning editor, Professor Brian Heaton, is the key player in the field, and has brought together here a team of authors to cater for specialists, and researchers in industry and academia.




From Solid State Chemistry to Heterogeneous Catalysis


Book Description

Heterogeneous catalysis is deeply founded on solid state chemistry, but the relationship between the two often appears to be elusive in many cases. It is generally difficult to relate the allusion of symmetry to the crystal structure and the defect chemistry or acid-base properties to the surface reconstruction and extended defects that in most cases are the basis of physicochemical properties and solids applications. This book provides insights into solid state chemistry in order to widen the vision of heterogeneous catalysis. It covers a broad range of solid state related topics, including symmetry and structure organization, bonding, and methods for structure elucidation, as well as defects formation and their implications in heterogeneous catalysis.

Each volume in the series is published either annually or biennially and is a superb reference point for researchers. www.rsc.org/spr




Catalysis


Book Description

NMR methods have for a considerable time been standard processes for the analysis of molecular structure: so much so that they are now universally regarded as indispensable for this purpose. Nevertheless, with the passage of time, NMR methodology has been elaborated to levels of ever increasing complexity and analytical sophistication so that the non specialist may now be readily excused for the belief that for anything beyond relatively elementary methods one would be well advised to work in collaboration with the specialist experts. The application of NMR methods to the field of catalysis occurred, in the main, relatively late in the day, mainly be cause those catalysts of greatest industrial importance, that is heterogeneous catalysts, are solids and so require special NMR methods if usefully narrow NMR lines are to be ob servable. Even so, magic-angle spinning NMR methodology is now thoroughly well established and is finding increasing use in the study of catalyst structure. Of course, conventional NMR methods have been used for a considerable time for the analysis of the products of catalytic reactions. Chapter 1 of the present volume by Professor Jacques Fraissard and his collaborators is designed to give an account of the application of NMR methods to the field of catalysis, but not including the conventional use of NMR for reaction product analysis, since this is already well covered in the existing NMR literature.
