This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-assembled monolayers (SAMs) generated from adsorption of the tridentate adsorbate having a cyclohexane ring as a platform were studied. The first generation of these SAMs was derived form cyclohexane-cis,cis-1,3,5-triyltrimethanethiol (CyTSH) and (cis,cis-1,3,5-trimethylcyclohexane-1,3,5-triyl)trimethanethiol (3C1CyTSH). Thin films prepared by the adsorption of these molecules onto the surface of gold were characterized by ellipsometry, contact angle goniometry, polarization modulation infrared reflection absorption spectroscopy (PM-IRRAS), and X-ray photoelectron spectroscopy (XPS). CyTSH was found to generate multilayer thin films with many unbound thiol species and oxidized sulfur moieties (e.g., disulfides and sulfone). In contrast, 3C1CyTSH was found to generate monolayer films in which ~90% of the thiols were bound to the surface of gold (~10% unbound), and there were no oxidized sulfur species. In comparing CyTSH and 3C1CyTSH, the methyl groups of 3C1CyTSH impart rigidity to the structure, which significantly enhances the chemisorption of sulfur to the surface of gold. Ellipsometric measurements and analysis by XPS indicate that the thickness of the SAM formed from 3C1CyTSH is ~5 Å. The second generation of these SAMs generated from the analogs of the R3C6H6(CH2SH)3 (abbreviated as 3CnCyTSH) where R = -(CH2)nH and n = 1, 3, 8 and 13 were also examined. Characterization of the SAMs revealed that all sulfur atoms of these tridentane adsorbates are bound to the surface of gold and generated loosely packed monolayer thin films with lower packing densities of the alkyl chains than a normal alkanethiolate SAM (C18SH). The trends in packing density and conformational order for these SAMs decreased as follows: C18SH ” 3C13CyTSH > 3C8CyTSH > 3C3CyTSH. A preliminary study of the thermal stability of this series of SAMs by XPS measurements has shown that the tridentate adsorbates (3CnCyTSH) are more stable than the normal alkanethiolate SAM (C18SH), a characteristic that is attributable to the chelating effect. Finally, a new pyridyl-based adsorbate (C18OPDSH) was synthesized and used to form SAMs. This SAM was characterized and the data was compared to those generated from the normal alkanethiol C18SH and C18OBDSH. XPS spectra display that a lone electron pair of pyridyl nitrogen atom of C18OPDSH interacts weakly with gold surface with some unbound thiols on the film. Both C18OPDSH and C18OBDSH adsorbates generate loosely and disordered packed thin films when compared to a normal alkanethiol (C18SH). The evaluation of the thermal stability using XPS measurement indicates that the C18OPDSH SAM is more stable when compared to both C18OBDSH and C18SH SAMs.

Gold is a soft metal occurring naturally as particles in quartz oras nuggets. Gold was initially used extensively in coinage andjewellery and has recently found applications in biochemistry,medicine and material science. Gold readily forms organometalliccompounds (R-Au-L with L = sulphide, phosphine and isocyanide),oxides and halides. Silver is a ductile metal which was used incoinage and for mirrors. It is now used for jewellery, electricalconductors, dental and surgical components. Silver forms stablesilver halides for use in Photography and i.r. spectroscopy as asupport material. Other silver compounds are also used incatalysis. This volume contains 16 chapters dealing with calculations onorganogold compounds, physical and spectroscopic properties (NMR,ESR, PES, Mossbauer spectra), thermochemical and analyticalproperties, the synthesis and uses of the title compounds and theirreactions such as rearrangements, pyrolysis and photochemicalreactions. The medicinal use of organogold compounds and theincreased use of gold-thiol monolayers are also summarized. Each of the chapters has been prepared by leading scientists inthis field making this volume invaluable for researchers inacademia and industry working with gold and silver, inbiochemistry, pharmaceutical and materials chemistry. Organic compunds containg Nitrogen are of outstanding importnce inbiochemistry and in environmental systems. This volume gives asound introduction into physical chemistry of amino, nitriso, nitroand related functional groups. This volume is now available in electronic format from BooksOnline.

Book Synopsis Metal Nanoparticles for Catalysis by : Franklin Tao
Download or read book Metal Nanoparticles for Catalysis written by Franklin Tao and published by Royal Society of Chemistry. This book was released on 2014-06-12 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catalysis is a central topic in chemical transformation and energy conversion. Thanks to the spectacular achievements of colloidal chemistry and the synthesis of nanomaterials over the last two decades, there have also been significant advances in nanoparticle catalysis. Catalysis on different metal nanostructures with well-defined structures and composition has been extensively studied. Metal nanocrystals synthesized with colloidal chemistry exhibit different catalytic performances in contrast to metal nanoparticles prepared with impregnation or deposition precipitation. Additionally, theoretical approaches in predicting catalysis performance and understanding catalytic mechanism on these metal nanocatalysts have made significant progress. Metal Nanoparticles for Catalysis is a comprehensive text on catalysis on Nanoparticles, looking at both their synthesis and applications. Chapter topics include nanoreactor catalysis; Pd nanoparticles in C-C coupling reactions; metal salt-based gold nanocatalysts; theoretical insights into metal nanocatalysts; and nanoparticle mediated clock reaction. This book bridges the gap between nanomaterials synthesis and characterization, and catalysis. As such, this text will be a valuable resource for postgraduate students and researchers in these exciting fields.
