Sodium Tungsten Bronze

The effects of the precursor solution, solvent, heating temperature, and moisture concentration on the quality (i.e., crystallinity) of the products were systematically investigated. The mechanisms for the particle formation and the chemical reactions involved in this process were also studied. By varying the atomic ratio of sodium to tungsten in the precursor solution, sodium tungsten bronze particles in the cubic (Na0.70WO3) and tetragonal (Na0.57WO3) phases were monophasically produced. Particles in both phases showed near infrared (NIR) shielding properties. However, cubic-phase particles (Na0.70WO3) possessed higher visibility in the visible light range due to their lower impurity content and higher crystallinity. Keywords: NIR shielding particles; Sodium tungsten bronze crystal; Aerosol-assisted synthesis. INTRODUCTION because of its unique optical properties (Berning and Turner, 1957; Berning, 1983).

Approaches to Mitigate Metal Catalyst Deactivation in Solid Oxide Fuel Cell (SofC) Fuel Electrodes Abstract While Ni/YSZ cermets have been used successfully in SOFCs, they also have several limitations, thus motivating the use of highly conductive ceramics to replace the Ni components in SOFC anodes. Ceramic electrodes are promising for use in SOFC anodes because they are expected to be less susceptible to sintering and coking, be redox stable, and be more tolerant of impurities like sulfur. In this thesis, for catalytic studies, the infiltration procedure has been used to form composites which have greatly simplified the search for the best ceramics for anode applications. In the development of ceramic fuel electrodes for SOFC, high performance can only be achieved when a transition metal catalyst is added. Because of the high operating temperatures, deactivation of the metal catalyst by sintering and/or coking is a severe problem. In this thesis, two approaches aimed at mitigating metal catalyst deactivation which was achieved by: 1) designing a catalyst that is resistant to coking and sintering and 2) developing a new method for catalyst deposition, will be presented. -
Bronze Compounds
Montclair State University Montclair State University Digital Commons Theses, Dissertations and Culminating Projects 5-2020 A Study and Synthesis : Bronze Compounds Patricia Rose Olsen Follow this and additional works at: https://digitalcommons.montclair.edu/etd Part of the Chemistry Commons ABSTRACT The focus of this thesis is the investigation of ternary and quaternary reduced metal oxide compounds termed “bronzes.” The name bronze originally arose from the metallic-like luster of these compounds. Examples of these compounds range from sodium tungsten oxides to the more complex potassium cesium molybdenum oxides. These compounds are crystalline solids at room temperature. The “bronzes” are compounds that have been studied since their initial synthesis by Wohler in 1824. These compounds belong to a class of compounds that are known as “nonstoichiometric” compounds. The general formula for reduced ternary transition metal oxides is AxMyOz. In this general formula, the value of x is less than one, but greater than 0. The compounds vary in crystal structures due to the radius of the electropositive element, M. The compounds also vary in physical properties because of their crystal structures and energy level occupations. The compounds can range in color from purple to yellow and range in electrical conductivity from metallic behavior to semiconducting behavior. The history of these compounds, including a classification of known bronze phases, will be reviewed with a focus on complex molybdate phases. Experimental methods, including experimental searches for new phases using ceramic synthesis techniques and electrolytic growth, and analysis of resulting products by powder x-ray diffraction and SEM studies will be discussed in this thesis. -
Toxicological Profile for Tungsten
TUNGSTEN 73 4. CHEMICAL AND PHYSICAL INFORMATION 4.1 CHEMICAL IDENTITY Tungsten is a naturally occurring element found in the earth=s surface rocks. Tungsten metal typically does not occur as the free element in nature. Of the more than 20 tungsten-bearing minerals, some of the commonly used commercial ones include feberite (iron tungstate), huebnerite (manganese tungstate), wolframite (iron-manganese tungstate), and scheelite (calcium tungstate). Tungsten appears in Group VIB of the periodic table. Natural tungsten is composed of five stable isotopes: 180W (0.12%), 182W (26.5%), 183W (14.3%), 184W (30.6%), and 186W (28.4%). Twenty-eight radioactive isotopes of tungsten are known; most of these isotopes have short half-lives. Tungsten forms a variety of different compounds, such as tungsten trioxide, tungsten carbide, and ammonium paratungstate (Penrice 1997a). Information regarding the chemical identity of elemental tungsten and tungsten compounds is located in Table 4-1. 4.2 PHYSICAL AND CHEMICAL PROPERTIES Tungsten has several common oxidation states (e.g., W[0], W[2+], W[3+], W[4+], W[5+], and W[6+]). However, tungsten alone has not been observed as a cation. Tungsten is stable, and therefore its most common valence state is +6. The naturally occurring isotopes of tungsten are 180 (0.135%), 182 (26.4%), 183 (14.4%), 184 (30.6%), and 186 (28.4%). Artificial radioactive isotopes of tungsten are 173–179, 181, 185, and 187–189 (O’Neil et al. 2001). Elemental tungsten metal is stable in dry air at room temperature. Above 400 °C, tungsten is susceptible to oxidation. Tungsten is resistant to many chemicals and is also a good electrical conductor (Penrice 1997a). -

The 2À tungstic acids were synthesized from WO4 aqueous solutions under a variety of conditions of pH, temperature and W(VI) concentrations. The thermal decomposition of the tungstic acids into WO3 was analysed by TG and DSC methods. Nano-sized WO3 powders with different morphological characteristics were obtained by thermal treatment of the tungstic acids at 500 8C in air atmosphere. The morphologies of WO3 powders were characterised by scanning electron microscopy and infrared absorption spectroscopy. Patterns of infrared spectra were related with distinct powder morphologies. # 2003 Elsevier Ltd. All rights reserved. Keywords: A. Oxides; B. Chemical synthesis; C. Fourier transform infrared spectroscopy; C. Scanning electron microscopy 1. Introduction Tungsten trioxide (WO3) has been the subject of great interest due to its special electrochromic [1,2], gas sensing [3,4] and catalytic properties [5]. In these applications, the morphological characteristics of the materials like grain size or shape are very important and depend strongly on the preparation method. Therefore, WO3 has been prepared, both in the form of powders and thin films, by a plethora of methods which include chemical vapour deposition [6], sol-gel procedures [7], spray pyrolysis [8], and r.f. -

[email protected] Abstract In this work we demonstrate the feasibility of hard X-rays operando XAS in photoelectrochemistry. WO3, one of the most studied photoanodes for water splitting and for environmental remediation, is here studied at the W LIII-edge. This guarantees the direct observation of the W 5d band. The material, that is preliminary fully characterized in terms of its photoelectrochemical features, is studied in a three-electrode spectroelectrochemical cell, while X-ray absorption is measured in the X- ray absorption near edge structure (XANES) region. The recording of differential spectra and the monitoring of X-ray absorption at constant energy are used to compensate for the little XANES differences expected in the dark and under visible light illumination, which otherwise risks to be masked by experimental errors and/or after signal manipulation for data analysis. The results point to the filling of the W t2g orbitals under illumination, that is followed by a structural rearrangement that compensates for the accumulation of electrons in the conduction band under open circuit (OC) conditions. -
