Ruthenium-coated ruthenium oxide nanorods

Applied Physics Letters, 2004
The role of ruthenium and its oxides in catalysis, electrochemistry, and electronics is becoming increasingly important because of the high thermal and chemical stability, low resistivity, and unique redox properties of this metallic system. We report an observation of RuO2 nanorods decorated with nanometer size Ru metal clusters.

A study of Ruthenium catalysts on oxide supports

Surface Science Letters, 1989
Abstract Ruthenium clusters on γ-Al 2 O 3 and SiO 2 supports, prepared by different impregnation methods, are studies by thermal programmed reduction (TPR), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS) and chemisorption techniques.

Catalytic Oxidation of Methanol by Ruthenium Oxides

Australian Journal of Chemistry, 1990
The electrocatalytic behaviour of carbon-supported ruthenium oxide electrodes for oxygen evolution and methanol oxidation in acid solutions is reported. Physical characterization of the electrodes by X-ray diffraction, X-ray photoelectron and 99Ru Mossbauer spectroscopies indicated the ruthenium to be present as a mixture of RuIV oxides including the ...

Oxidation of ruthenium oxide deposits by ozone

Radiochimica Acta, 2008
Summary During a hypothetical severe accident on a nuclear Pressurized Water Reactor (PWR), the formation of highly radiotoxic RuO4(g) may occur in the reactor containment building, resulting from the interactions of ruthenium oxide deposits with the oxidising medium induced by air radiolysis.

Radiolytic Oxidation of Ruthenium Oxide Deposits

Nuclear Technology, 2008
AbstractIn the case of a hypothetical severe accident in a nuclear pressurized water reactor, the formation of radiotoxic RuO4(g) may occur in the reactor containment building, resulting from the interactions of ruthenium oxide deposits with the oxidizing medium induced by air radiolysis.

Oxidative Dehydrogenation of Ethylenediamine Coordinated to Ruthenium with Hexafluoroacetylacetonate, Induced by Electrochemical Oxidation of Ruthenium(II) to Ruthenium(III)

Bulletin of the Chemical Society of Japan, 1992
Abstract Two mixed-ligand complexes, [Ru(hfac)2(en)] and [Ru(hfac)(en)2]PF6 (en = ethylenediamine and hfac− = hexafluoroacetylacetonate ion), were synthesized. The oxidative dehydrogenation of their en ligand was studied in acetonitrile solutions. Each complex underwent a Nernstian one-electron oxidation at platinum electrodes.

Electrochemical Capacitors Using Hydrous Ruthenium Oxide and Hydrogen Inserted Ruthenium Oxide

Journal of The Electrochemical Society, 1998
Electrochemical capacitors made with hydrous ruthenium oxide and hydrogen inserted hydrous ruthenium oxide electrode materials were investigated. The electrochemical behavior of in the potential range of −0.2 to 1.3 V vs. saturated calomel electrode (SCE) was characterized using a cyclic voltammetry technique.

Ruthenium as an Effective Nitric Oxide Scavenger

Current Topics in Medicinal Chemistry, 2004
Whilst nitric oxide (NO) has emerged as one of the most versatile and ubiquitous molecules in the human body with a diverse range of physiological functions, dysfunction in NO biosynthesis or metabolism has led to the pathogenesis of a number of disease states.
