WORRELLUniversity of South Florida This volume is dedicated to the memory of EARL L. MUETTERTIES ( 1927- 1984) He was a chemist’s chemist and a friend to inorganic Syntheses PREFACE I welcome this opportunity to contribute to Inorganic Synrheses by editing this volume, because this series has been of considerable help to me and my col- leagues for more than thirty years. It is appropriate, I believe, to express my appreciation and the appreciation of Inorganic Syntheses to all those who were involved in producing this volume. Special thanks must go to the contributors and checkers, who provided and checked the substantive material of the volume. However, additional thanks must go to the members of Inorganic Syntheses who contributed their time and expertise to help with the editing, because, without this assistance, this volume would not be nearly so complete as it is. I would like especially to thank John Bailar, Therald Moeller, and Thomas Sloan, who were particularly helpful during the editing process. Further, I would also like to express my appreciation to Duward Shriver, for his help in providing guidance and for his editorial assistance, as well. I must extend my sincere appreciation to my secretary, Elena Drob, whose patience and efforts beyond the call of duty helped to make this volume possible. 1 wish to call special attention to the Special Hazard Notice Appendix at the back of this volume. Finally, I wish to mention the dedication of this volume to Earl Muetterties, whose untimely passing has saddened us all. He was the Editor of Volume 10 of this series and continued to contribute to the success of later volumes. STANLEYKIRSCHNER Derroir. Michigan December 1984 ~ Revious volumes of Inorganic Synrhescs are available. Volumes I-XVI can be ordered from R. E. Krieger Publishing Co., Inc., P.O.Box 9542, Melbourne, Florida 32901; Volume XVII is available from McGraw-Hill, Inc.; ind Volumes XVIII-XXII can be obtained from John Wiley & Sons, Inc. ix NOTICE TO CONTRIBUTORS AND CHECKERS The Inorganic Syntheses series is published to provide all users of inorganic substances with detailed and foolproof procedures for the preparation of important and timely compounds. Thus, the series is the concern of the entire scientific community. The Editorial Board hopes that all chemists will share in the re- sponsibility of producing Inorganic Syntheses by offering their advice and as- sistance in both the formulation of and the laboratory evaluation of outstanding syntheses. Help of this kind will be invaluable in achieving excellence and pertinence to current scientific interests. There is no rigid definition of what constitutes a suitable synthesis. The major criterion by which syntheses are judged is the potential value to the scientific community. An ideal synthesis is one that presents a new or revised experimental procedure applicable to a variety of related compounds, at least one of which is critically important in current research. However, syntheses of individual com- pounds that are of interest or importance are also acceptable. Syntheses of compounds that are readily available commercially at reasonable prices are not acceptable. Corrections and improvements of syntheses already appearing in Inorganic Syntheses are suitable for inclusion. The Editorial Board lists the following criteria of content for submitted man- uscripts. Style should conform with that of pvious volumes of Inorganic Syntheses. The introductory section should include a concise and critical summary of the available procedures for synthesis of the product in question. It should also include an estimate of the time required for the synthesis, an indication of the importance and utility of the product, and an admonition if any potential hazards are associated with the procedure. The Procedure should present detailed and unambiguous laboratory directions and be written so that it anticipates possible mistakes and misunderstandings on the part of the person who attempts to du- plicate the procedure. Any unusual equipment or procedure should be clearly described. Line drawings should be included when they can be helpful. All safety measures should be stated clearly. Sources of unusual starting materials must be given, and, if possible, minimal standards of purity of reagents and solvents should be stated. The scale should be reasonable for normal laboratory operation, and any problems involved in scaling the procedure either up or down should be discussed. The criteria for judging the purity of the final product should be xi xii Notice to Contributors and Checkers delineated clearly. The section on Properties should supply and discuss those physical and chemical characteristics that are relevant to judging the purity of the product and to permitting its handling and use in an intelligent manner. Under References, all pertinent literature citations should be listed in order. A style sheet is available from the Secretary of the Editorial Board. The Editorial Board determines whether submitted syntheses meet the general specifications outlined above. Every procedure will be checked in an independent laboratory, and publication is contingent upon satisfactory duplication of the syntheses. Each manuscript should be submitted in duplicate to the Secretary of the Editorial Board, Professor Jay H. Worrell, Department of Chemistry, University of South Florida, Tampa, FL 33620. The manuscript should be typewritten in English. Nomenclature should be consistent and should follow the recommen- dations presented in Nomenclature of Inorganic Chemistry, 2nd Ed., Butter- worths & Co., London, 1970 and in Pure Appl. Chem., 28, No. 1 (1971). Abbreviations should conform to those used in publications of the American Chemical Society, particularly Inorganic Chemisrry. Chemists willing to check syntheses should contact the editor of a future volume or make this information known to Professor Worrell.

    THE LONG SEARCH FOR STABLE TRANSITION METAL ALKYLS Nobel Lecture, December 11, 1973 by G EOFFREY W ILKINSON Imperial College of Science & Technology, London, England Chemical compounds in which there is a single bond between a saturated car- bon atom and a transition metal atom are of unusual importance. Quite aside from the significance and role in Nature of the cobalt to carbon bonds in the vitamin B 12 system and possible metal to carbon bonds in other biological systems, we need only consider that during the time taken to deliver this lec- ture, many thousands, if not tens of thousands of tons of chemical compounds are being transformed or synthesised industrially in processes which at some stage involve a transition metal to carbon bond. The nonchemist will pro- bably be most familiar with polyethylene or polypropylene in the form of do- mestic utensils, packaging materials, children’s toys and so on. These materials are made by Ziegler-Natta* or Philipps’ catalysis using titanium and chro- mium respectively. However, transition metal compounds are used as catalysts in the synthesis of synthetic rubbers and other polymers, and of a variety of simple compounds used as industrial solvents or intermediates. For example alcohols are made from olefins, carbon monoxide and hydrogen by use of cobalt or rhodium catalysts, acetic acid is made by carbonylation of methanol using rhodium catalysts and acrylonitrile is dimerised to adiponitrile (for nylon) by nickel catalysts. We should also not forget that the huge quantities of petroleum hydrocarbons processed by the oil and petrochemical industry are re-formed over platinum, platinum-rhenium or platinum-germanium sup- ported on alumina.

  • Nanopatterns Regulate Electricity 8 February 2007
    Nanopatterns Regulate Electricity 8 February 2007 layers alternate with layers of sodium atoms ordered on a nanoscale. The concentration of sodium atoms can vary over a large range, and the detailed arrangement of the sodium atoms determines the electrical properties of the material. When they are far apart from each other, each atom acts as a well confining the electrons constituting the current flow - the material becomes an insulator. If they are arranged in lines, they form wire-like structures allowing current to flow along one direction. Alan Tennant, head of the department Magnetism at the Hahn-Meitner-Institut explains that "the electrons responsible for the current flow behave like waves and they like to arrange their wavelength 80% filled layer of sodium atoms. Credit: Hahn-Meitner- and their behaviour to fit the predefined structure. Institut In this way the electrons can be controlled by the chemical composition of the material.

As the Lithium deposits are depleting the cost of Lithium-ion batteries is increasing. Sodium- ion batteries can be introduced as an alternative technology which can replace expensive Lithium-ion batteries. Sodium sources are highly abundant and therefore Sodium-ion batteries could be made cheaper than Lithium-ion batteries. A number of cathode materials which were accommodated in Lithium-ion batteries have also been tested as cathode materials for Sodium-ion batteries. This research was based on a Sodium-ion battery which cathode was prepared using Sodium cobalt phosphate. The cathode material was prepared using a simple solid-state reaction between Cobalt (II) oxide and Sodium phosphate. The prepared material was characterized using powder XRD. Charge- discharge cycles, cyclic voltammetry analyzing, impedance curve matching to obtain equivalent circuit was used in order to analyze the performance of the prepared cathode in the battery. The discharge capacity of the cathode was calculated as 9.58 mA h g-1.

The Seebeck coefficent of this material exceeds unity and it shows different types of magnetic behaviour depending on the Na content in NaxCoO2. A preliminary study is elaborated for obtaining the layered sodium cobalt oxide materials by hydrothermal synthesis method. In order to discover conditions for the hydrothermal synthesis of NaxCoO2 phase, we studied the influence of the concentration mineralizer, the temperature, the reaction time and Co(OH)2 concentration in the formation of desired phase, NaxCoO2 phase. From these results, it is encouraging that NaxCoO2 pure phase is possibly produced if suitable experimental conditions are chosen. The low temperature and pressure synthesis conditions propose the hydrothermal method that a facile and cheaper preparation method of layered sodium cobalt oxide.

  • Electrode Materials for Na-Ion Batteries:A New Route for Low-Cost Energy Storage
    Electrode materials for Na-ion batteries:a new route for low-cost energy storage. Massaccesi Valentina Instituto Superior Técnico, Universidade Técnica de Lisboa Abstract. With the imminent exhaustion of fossil fuel resources and increasing environmental problems, a variety of renewable and clean energy sources, such as the wind and sun, are growing rapidly . The use of these discontinuous energy source requires a large-scale energy storage system (ESS) to shift electrical energy from peak to off-peak periods, with the aim to realize smart grid management. Among various energy storage technologies, room-temperature stationary sodium-ion batteries have attracted great attention particularly in large scale electric energy storage applications for renewable energy and smart grid because of the huge abundant sodium resources and low cost1. The research work presented in this thesis deals with the investigation of electrochemical properties of electrode materials for this tipe of batteries, in particular NaxCoO2 as cathodic compound. In the first part of this thesis, several synthetic routes have been studied. The active materials obtained have been investigated by XRD and ICP-MS analysis to evaluate the correlation between stechiometry and crystal structure. A morphological characterization was conduced using SEM. In the second part of this thesis, matherials have been tested electrochemically by GCPL, CV and PEIS. Finally an optimization of the system have been conduced evaluating the use of different elecrolytes and binders. Key words: Na-Ion Batteries, NaxCoO2 Cathode Material, X-Ray Powder Diffraction, Electrochemical Characterization, Electrochemical Impedance Spectroscopy. Introduction Lithium-ion batteries, the most common type of secondary cells found in almost all portable electronic devices, are a possible solution to Energy storage has become a growing global these larger global concerns1.

Committee Chairperson: Professor Jean-Marie Basset Committee Members: Professor Kazuhiro Takanabe, Professor Udo Schwingenschlogl, Professor Joumana Toufaily. 3 © February, 2017 Ali Hamieh All Rights Reserved 4 ABSTRACT New Route to Synthesize Surface Organometallic Complexes (SOMC): An Approach by Alkylating Halogenated Surface Organometallic Fragments. Ali I. Hamieh The aim of this thesis is to explore new simpler and efficient routes for the preparation of surface organometallic complexes (SOMC) for the transformation of small organic molecules to valuable products. The key element in this new route relies on surface alkylation of various halogenated surface coordination complexes or organometallic fragments (SOMF). The first chapter provides an overview on the origin of organometallic compounds, their classical synthesis, characterization and some of their applications In the second chapter, novel silica-supported tungsten oxo-trimethyl complex [(≡Si-O- )W(=O)Me3] was synthesized using the new SOMC synthetic approach. WOCl4 was grafted on the surface of silica, partially dehydroxylated at 700°C (SiO2-700), and [(≡Si-O- )W(=O)Cl3] was produced. The supported complex methylated with ZnMe2 and transformed into [(≡Si-O-)W(=O)Me3], which was fully characterized. It was found that complex [(≡Si-O-)W(=O)Me3] has two conformational isomers at room temperature.
