Available in PDF, EPUB and Kindle. Book excerpt: Ultra-small metal and metal-oxide clusters are produced in the gas phase with laser vaporization, coated with ligands, and captured in solution with the use of a laser vaporization flowtube reactor. Their properties were investigated with mass spectrometry, numerous spectroscopic methods, and computational chemistry. Observed chromium oxide clusters coated with acetonitrile ligands have stable metal-oxide stochiometries previously observed in gas phase experiments. Production and capture of aluminum clusters yields aluminum trimer with acetonitrile ligands as the primary clusters. Small aluminum oxides and larger aluminum clusters are also observed. Separate gas phase X-ray studies were performed to investigate cluster-ligand interactions. Ligand addition to cobalt clusters revealed drastic quenching of magnetic moments for both benzene and carbonyl ligands.

Book Synopsis Laser Synthesis and Spectroscopy of Ligand-coated Transition Metal Oxide Nanomaterials by : Melissa Pressley Woodard
Download or read book Laser Synthesis and Spectroscopy of Ligand-coated Transition Metal Oxide Nanomaterials written by Melissa Pressley Woodard and published by . This book was released on 2019 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: A laser vaporization flow reactor (LVFR) has been utilized for the gas phase synthesis of ligand-coated nanomaterials. Exploration into the gas phase synthesis of ultra-small nanoclusters and nanoparticles can help scientists understand the differences in material structure and properties in the nanoscale compared to the bulk material. The structural, electronic, and vibrational properties of nanomaterials are studied by mass spectrometry, spectroscopy, electron microscopy and computational calculations. Transition metal oxides are of particular interest due to their applications in catalysis, fuel cells, magnetic storage, photovoltaics, and other electronic devices. Chromium oxide and molybdenum oxide were studied in these synthesis experiments. Ultra-small chromium oxide nanoclusters were obtained in solution with stoichiometries not typically observed in the bulk material. We find that the complex CrxOy(MeCN)z solution contains a mixture of cluster sizes and isomers making spectroscopic interpretation difficult. Molybdenum oxide nanorods were produced with a morphology unlike other molybdenum oxide nanorods made by more traditional synthetic methods. These nanorods are much smaller and have increased catalytic activity over other molybdenum oxide nanomaterials but have optical and electronic properties similar to those of other molybdenum oxide nanorods.

Book Synopsis Metal-Metal Bonds and Clusters in Chemistry and Catalysis by : John P. Fackler Jr.
Download or read book Metal-Metal Bonds and Clusters in Chemistry and Catalysis written by John P. Fackler Jr. and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains a series of papers and abstracts from the 7th Industry-University Cooperative Chemistry Program symposium held in the spring of 1989 at Texas A&M University. The symposium was larger than previous IUCCP symposia since it also celebrated the 25 years that had elapsed since the initial discovery by F. A. Cotton and his co-workers of the existence of metal-metal quadruple bonds. Cotton's discovery demonstrated that multiple bonding in inorganic systems is not governed by the same constraints observed in organic chemistry regarding s and p orbital involvement. The d orbitals are involved in the multiple bonding description. The quadruple bond involves considerable d orbital overlap between adjacent metal centers. Part I of this series of papers focuses upon the impact of this discovery and describes further contributions to the development of the field. Multiple metal-metal bonding now is known to permeate broad areas of transition metal chemistry. The understanding of metal-metal bonding that developed as a result of the discovery of multiple metal-metal bonding awakened a new chemistry involving metal clusters. Clusters were defined by Cotton to be species containing metal-metal bonding. Clusters in catalysis therefore seemed a logical grouping of papers in this symposium. Clusters play an every increasing role in the control of chemical reactions. Part II of this book describes some of the interesting new developments in this field. In Part III the papers examine the role clusters play in describing and understanding solid state materials.

Book Synopsis Metal Clusters and Their Reactivity by : Zhixun Luo
Download or read book Metal Clusters and Their Reactivity written by Zhixun Luo and published by Springer Nature. This book was released on 2020-10-31 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses current techniques and instrumentation for cluster chemistry. It addresses both the experimental and theoretical aspects of gas-phase metal cluster reactivities, especially those pertaining to pollution removal, energetic reactions and corrosion and anticorrosion. These metal cluster systems have attracted enormous interest as they display a completely new class of physical, chemical, electronic, magnetic and catalytic properties. As these properties change with size and composition, it can thus be understood how their nature evolves from atoms to bulk solids. The book offers readers a basic understanding of the structural chemistry and reactivity of metal clusters in both gas-phase and wet chemistry. Further, the lessons they learn here regarding metal cluster chemistry will prepare researchers for the study of condensed phase dynamics that pertain to wet chemical synthesis, soft-landing deposition and cluster assembly.
Book Synopsis Advances in Metal and Semiconductor Clusters by : M.A. Duncan
Download or read book Advances in Metal and Semiconductor Clusters written by M.A. Duncan and published by Elsevier. This book was released on 2001-07-10 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: In previous volumes in this series, Advances in Metal and Semiconductor Clusters, the focus has been on atomic clusters of metals, semiconductors and carbon. Fundamental gas phase studies have been surveyed, and most recently scientists have explored new materials which can be produced from clusters or cluster precursors. In this latest volume, the focus shifts to clusters composed primarily of non-metal molecules or atoms which have one or more metal atoms seeded into the cluster as an impurity. These clusters provide model systems for metal ion solvation processes and metal-ligand interactions. Metal-ligand bonding underlies the vast fields of organometallic chemistry, transition metal chemistry and homogeneous catalysis. Catalytic activity, ligand displacement reactions and photochemical activity depend on the specific details of metal-ligand bonding. Likewise, metal ions are ubiquitous in chemistry and biology and weaker electrostatic interactions play a leading role in their function. In solution, metals exist in different charge states depending on the conditions, and the solvation environment strongly influences their chemistry. Many enzymes have metal ions at their active sites, and electrostatic interactions influence the selectivity for metal ion transport through cell membranes. Metal ions (e.g., Mg+, Ca+) are deposited into the earth's atmosphere by meteor ablation, resulting in a rich variety of atmospheric chemistry. Similarly, metal ions ( Mg+) have been observed in planetary atmospheres and in the impact of the comet Shoemaker-Levy 9 on Jupiter. In various circumstances, the electrostatic interactions of metal ions determine the outcome of significant chemistry. Cluster chemistry has made significant contributions to the understanding of these stronger metal ligand interactions and weaker metal ion solvation interactions. In this volume, the authors explore a variety of work in these general areas, where new cluster science techniques in the gas phase have made it possible to synthesize new kinds of complexes with metals and to measure their properties in detail.
Book Synopsis Metal Clusters in Chemistry by : Pierre Braunstein
Download or read book Metal Clusters in Chemistry written by Pierre Braunstein and published by Wiley-VCH. This book was released on 2000-01-11 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal cluster chemistry is at the cutting edge between molecular and solid-state chemistry and has therefore had a great impact on the researchers working on organic, coordination, and solid-state chemistry, catalysis, physics, and materials science. The development of new sophisticated synthetic techniques has led to enormous progress in the synthesis of this diverse class of compounds. The number of clusters is growing rapidly, since the possible variations in the metal and ligand sphere are numerous. Modern bonding theories, such as the isolobal principle, have allowed a better understanding of the structures and properties of metal clusters, and thus paved the way for the usage of these versatile materials. Catalysis and nanomaterials are just two of the very promising application-oriented fields. Seventy six contributions, written by world experts in this research field, provide extensive coverage of different aspects of cluster chemistry, ranging from synthesis, structure determination, and dynamics to applications. Up-to-date information, including an impressive collection of structural data and illustrations, extensive coverage of the most important publications of the last decade, and many more features make this three-volume set a complete single-source guide for all researchers working in the area of cluster chemistry.
