Book Synopsis Synthesis, Characterization and Applications of Metal and Metal Oxide Nanoparticles by : Lawrence D'Souza
Download or read book Synthesis, Characterization and Applications of Metal and Metal Oxide Nanoparticles written by Lawrence D'Souza and published by . This book was released on 2005 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extensive literature survey of synthetic methods of metal and metal oxide nanoparticles has been done and presented in Chapter 1. This Chapter begins with a few definitions, a note on stabilization processes and reducing agents. Then it extends to various methods for the synthesis of metal and metal oxide nanoparticles and ends with a Table, which provides important applications of various nanoparticles, found in the literature. The primary objective of this work was to synthesize metal nanoclusters using polyoxometalate as stabilizers by 'bottom up' chemical synthesis. In Chapter 2-5, the synthesis, characterization and applications of polyoxometalate stabilized noble metal nanoclusters have been given. The catalytic life span shown by Pd nanoclusters in hydrogenation reactions is remarkable and deserves further exploration. The advantage of the present method of synthesis is due to its ease compared to literature reported protocols. Chapter er 6-7, describes novel routes to prepare high surface area zirconia as well as implantation of pre-prepared Pd and Pt nanoclusters on its matrix to obtain heterogeneous catalysts. These catalysts have been examined for hydrogenation reactions and were found to be better catalysts in terms of Turnover frequency than literature reported catalysts, which can be applied to industrial applications. Chapter 8, describes application of dynamic light scattering (DLS) and UV-visible spectroscopy in following kinetics of nanoparticles formation. Finally, application of DLS in measuring particles of size ranging from 1-200 nm in diameter has been demonstrated.

Therefore, metal nanoparticle catalysts are an excellent candidate for the above-mentioned active and robust heterogeneous catalysts and this book provides an overview of this area. The present volume summarizes recent progress on nanoparticle catalysis for various organic transformations from simple redox reactions to complex asymmetric C–C bond forming reactions and also presents seminal studies on new technologies. It comprehensively summarizes advances in metal nanoparticle catalysis across several aspects including reaction manners, mechanistic investigations and new synthetic methodologies to encourage the use of metal nanoparticle catalysts for future organic synthesis.

Book Synopsis Monodisperse Platinum and Rhodium Nanoparticles as Model Heterogeneous Catalysts by :
Download or read book Monodisperse Platinum and Rhodium Nanoparticles as Model Heterogeneous Catalysts written by and published by . This book was released on 2008 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Model heterogeneous catalysts have been synthesized and studied to better understand how the surface structure of noble metal nanoparticles affects catalytic performance. In this project, monodisperse rhodium and platinum nanoparticles of controlled size and shape have been synthesized by solution phase polyol reduction, stabilized by polyvinylpyrrolidone (PVP). Model catalysts have been developed using these nanoparticles by two methods: synthesis of mesoporous silica (SBA-15) in the presence of nanoparticles (nanoparticle encapsulation, NE) to form a composite of metal nanoparticles supported on SBA-15 and by deposition of the particles onto a silicon wafer using Langmuir-Blodgett (LB) monolayer deposition. The particle shapes were analyzed by transmission electron microscopy (TEM) and high resolution TEM (HRTEM) and the sizes were determined by TEM, X-ray diffraction (XRD), and in the case of NE samples, room temperature H2 and CO adsorption isotherms. Catalytic studies were carried out in homebuilt gas-phase reactors. For the nanoparticles supported on SBA-15, the catalysts are in powder form and were studied using the homebuilt systems as plug-flow reactors. In the case of nanoparticles deposited on silicon wafers, the same systems were operated as batch reactors. This dissertation has focused on the synthesis, characterization, and reaction studies of model noble metal heterogeneous catalysts. Careful control of particle size and shape has been accomplished though solution phase synthesis of Pt and Rh nanoparticles in order to elucidate further structure-reactivity relationships in noble metal catalysis.

Book Synopsis Synthesis, Characterization, and Performance of Supported Molecular Catalysts by : Erjia Guan
Download or read book Synthesis, Characterization, and Performance of Supported Molecular Catalysts written by Erjia Guan and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals are dominant catalysts, being used in forms ranging from simple atomically dispersed (single-site) metal complexes to few-atom clusters to nanoparticles to bulk metals. Investigations of atomically dispersed metal complexes are drawing wide attention because their well-defined structures facilitate fundamental understanding of catalysis as well as offering new catalytic properties. In this work, we extend the field of atomically dispersed supported metal catalysts to dinuclear clusters to build a bridge between atomically dispersed metal complexes and few-atom clusters. Thus, the research extends the subject of atomically dispersed supported catalysts to supported metal pair-site catalysts, which have heretofore been little investigated because of their instability, lack of uniformity, and difficulty of precise synthesis. A separate, collaborative project reported on here includes characterization by in-situ X-ray absorption spectroscopy of the structures of single-site supported metals present as promoters in complex catalysts that contain metal nanoparticles for selective hydrogenation of nitroarenes. Iridium and rhodium pair-site catalysts supported on MgO were synthesized and characterized with infrared (IR) and X-ray absorption spectroscopies and high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM), supported by density functional theory (DFT) calculations done by collaborators. In-situ IR and X-ray absorption near edge structure (XANES) spectra were used to characterize the structural changes of the pair-sites under various treatment conditions, including ligand substitution reactions involving CO and hydrogen. Catalytic properties for ethylene hydrogenation and H-D exchange in the H2 + D2 reaction were tested and compared with those of single-site iridium and rhodium analogues as well as few-atom clusters of these metals supported on MgO. The pair-site catalysts on MgO activated by removal of ligands facilitate H2 dissociation much more rapidly than their single-site analogues and catalyze ethylene hydrogenation one to two orders of magnitude faster than their single-site analogues on MgO. The pair sites are active for ethylene hydrogenation even after being partially poisoned by CO, and, in contrast, the analogous single-site catalysts are fully poisoned. The results provide understanding of the roles of neighboring metal sites and the effects of ligands on pair sites catalysts, opening opportunities for synthesis of stable pairs of various metals on various supports. The benefits of such stable metal pair sites may extend to numerous reactions other than those investigated in this work. The single-site promoters investigated in this work are Sn cations on TiO2 supports that incorporate noble metal nanoparticle catalysts. These catalysts decidedly outperform the comparable unpromoted supported metals for hydrogenation of nitroarenes substituted with various reducible groups. X-ray absorption spectroscopy at the Sn K edge was used to characterize the structural changes in the single-site Sn in the catalysts as influenced by H2 and by nitrobenzene at 353 K and 1 atm. The changes in Sn–O coordination numbers and distances give evidence that the high activity and selectivity of these catalysts result from the creation of oxygen vacancies on the TiO2 surface associated with single-site Sn sites that lead to efficient, selective activation of the nitro group (in contrast to the other reducible group) coupled with reaction involving hydrogen atoms activated on the nearby metal nanoparticles.
