This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface organometallic chemistry is a new field bringing together researchers from organometallic, inorganic, and surface chemistry and catalysis. Topics ranging from reaction mechanisms to catalyst preparation are considered from a molecular basis, according to which the "active site" on a catalyst surface has a supra-molecular character. This. the first book on the subject, is the outcome of a NATO Workshop held in Le Rouret. France, in May. 1986. It is our hope that the following chapters and the concluding summary of recommendations for research may help to provide a definition of surface organometallic chemistry. Besides catalysis. the central theme of the Workshop, four main topics are considered: 1) Reactions of organometallics with surfaces of metal oxides, metals. and zeolites; 2) Molecular models of surfaces, metal oxides, and metals; 3) Molecular approaches to the mechanisms of surface reactions; 4) Synthesis and modification of zeolites and related microporous solids. Most surface organometallic chemistry has been carried out on amorphous high-surf ace-area metal oxides such as silica. alumina. magnesia, and titania. The first chapter. contributed by KNOZINGER. gives a short summary of the structure and reactivity of metal oxide surfaces. Most of our understanding of these surfaces is based on acid base and redox chemistry; this chemistry has developed from X-ray and spectroscopic data, and much has been inferred from the structures and reactivities of adsorbed organic probe molecules. There are major opportunities for extending this understanding by use of well-defined (single crystal) oxide surfaces and organometallic probe molecules.

Download or read book High Sensitivity Solid state NMR Spectroscopy of Catalytic Surfaces written by Ribal Jabbour and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast majority of chemical reactions used today in industry relies on heterogenous catalysts. Over the last three decades, many efforts were devoted at preparing well-defined, single-site supported organometallic catalysts that would combine the advantages of molecular complexes in terms of productivity, rates and selectivity, with an ease of separation and recyclability. The rational design of such systems depends on our ability to characterize with a high level of certainty their atomic-scale structure.Among the panoply of analytical techniques that can be applied to get a detailed knowledge of the active center, solid-state Nuclear Magnetic Resonance (NMR) spectroscopy under Magic Angle Spinning (MAS) plays an essential role. This spectroscopy suffers however from one key drawback, its inherently low sensitivity. This sensitivity issue is further exacerbated when the substrate of interest is located on a surface. The recent advent of hyperpolarization techniques and more specifically of Dynamic Nuclear Polarization (DNP) opens new opportunities for a highly detailed structural characterization of active sites in heterogeneous catalysts. The core of my PhD has concerned the implementation of advanced NMR methods of high sensitivity, namely DNP enhanced NMR spectroscopy and proton NMR spectroscopy, to unravel the atomic-scale structure of single-site, well defined heterogeneous catalysts. Three systems were investigated, all involved in key catalytic reactions. First, I elucidated the three-dimensional structure of an Iridium-NHC complex supported onto mesoporous silica. DNP enhanced NMR was applied to determine the structure of the surface species at various steps of the synthetic pathway. I showed that the implementation of conventional and selective REDOR (Rotational Echo Double Resonance) experiments between 29Si, 13C and 15N nuclei enables the measurement of distance constraints corresponding specifically to the Ir-NHC complex despite the presence of unreacted spectator species. The result is a well-defined structure where the Ir atom points to the porous cavity. This unexpected feature was interpreted by the residual presence of a cyclooctadiene (COD) ligand, coordinating the molecular Ir complex which could be confirmed by Extended X-Ray Absorption Fine Structure (EXAFS). I also demonstrated the use of static DNP-enhanced wide-line 195Pt NMR spectroscopy in combination with room-temperature proton-detected experiments to provide unique insight into the surface structure of a Platinum organometallic complex, representative of Pt single-site catalysts. Finally, I implemented proton double- and triple-quantum NMR experiments to unravel the structure of a new family of hetero-bimetallic surface complexes. The approach allowed the unambiguous determination of the number of hydride protons surrounding the metal centers. Different synthetic pathways yielded distinct surface structures that were elucidated by NMR in combination with IR spectroscopy and X-ray methods. Overall, several groundbreaking NMR methodologies were developed that are expected to become more widely implemented to guide the rational design of immobilized catalyst.
