The structure of the ultimate product of the interaction of ruthenium with thiourea (Thio) is studied by EPR. From hyperfine coupling (HFC) of the electron to 101Ru, it is found that the complex is a dimer of the tentative composition [{(Thio)5Ru}2(mu-SH)]4+, in which the unpaired electron is localized into the dxz(dyz) orbitals of two equivalent Ru nuclei. The EPR spectra of Ru(III) and Os(III) sulfides and tris-chelates 101Ru(SS)3 (SS is diethyldithiocarbamate, ethylxanthogenate ions) are studied. Interpretation of the g-tensors and HFC and analysis of the relevant literature data indicate that, in mononuclear complexes of Ru(III) and Os(III) bound to the S6 array, the unpaired electron is located into the dxy orbital and is appreciably delocalized to the ligands.

Nanocomposites were prepared by in situ redox intercalative polymerization method, in which alpha-RuCl3 microcrystals were soaked in pyrrole. Polypyrrole (PP) was formed as a result of the intercalation of pyrrole into the layered structure of RuCl3 crystal and the reaction between pyrrole and the host material. The appearance of polypyrrole was proven by infrared spectroscopy. The as-formed (PP)z+(RuCl3)z- nanocomposites were attached to paraffin-impregnated graphite or gold surfaces and studied by cyclic voltammetry and electrochemical nanogravimetry. The redox behaviour of the composite shows the electrochemical transformations of both the polypyrrole and RuCl3. The redox waves of PP are similar to those observed for very thin PP films. It attests that the response is originated from monolayer-like PP film situated between RuCl3 layers. The transport of the charge-compensating ions reflects the variation of the oxidation states of both PP and RuCl3. The nanocomposites behave as self-doped layers in the potential region when both constituents are charged, i.e., PP is partially oxidized while RuCl3 is partially reduced, since the electroneutrality is assured by mutual charge compensation. When PP is reduced, cations enter the layer to counterbalance the negative charge resulted from the reduction of Ru(III) to Ru(II). It was also found that the intercalation of water molecules is – albeit still substantial – smaller than that of pure RuCl3 microcrystals which is related to the presence of PP between the RuCl3 layers.

The oxidation of methyl glycol, ethyl glycol, diethylene glycol and tetraethylene glycol by alkaline hexacyanoferrate(III) using ruthenium(III) chloride as a homogeneous catalyst, was studied at constant ionic strength.The reaction velocity shows direct proportionality with respect to ruthenium(III) chloride concentrations.The reaction rate shows reverse proportionality with respect to hydroxide ion concentration.The reaction follows first order kinetics with respect to low concentrations of the organic substrate, but at high concentrations of the latter the reaction becomes independent with respect to the organic substrate concentrations.These data suggest the formation of an activated complex between the glycol anion and ruthenium(III) species.The complex, thus formed, slowly breaks up into the intermediate products and ruthenium(III) hydride species which in turn is further oxidized by taking more of hexacyanoferrate(III) in the subsequent steps.

Silicon nanowires (SiNWs, diameter a¿¥ 5 nm, and length a¿¼ I¼m) have been fabricated with metal- and SiO2-catalyses assisted by laser ablation. In the catalytic growth of single-crystalline SiNWs by pure metal catalysts (Fe, Ru, and Pr), Si {111} is found to be the most stable plane and wire growth axis is along <111>. The growth mechanism follows a vapor-liquid-solid process, and the synthesized SiNWs typically have metal-tips composed of metal and Si, such as FeSi2, RuSi3, and PrSi4, respectively. In sharp contrast, a crystalline growth axis of <111> and a wire growth axis of <112> are the result in the SiNWs catalyzed by SiO2. Besides, the SiO2-catalytic SiNWs generally have no tips at the wire ends. Distinctive growth mechanisms resulting from metal- and SiO2-catalyses will be discussed. Pressure effect on the longitudinal and transverse growing rates in the fabrication of SiNWs has been examined.

The synthesis, physical characterization, decontamination and some electrocatalytic properties of PtRu nanoparticles prepared using the microemulsion method are reported. The nanoparticles are synthesized by reduction with sodium borohydride of H2PtCl6 and RuCl 3 in a water-in-oil microemulsion of water/polyethylenglycol- dodecylether (BRIJ 30)/n-heptane. X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and energy dispersive analysis by X-rays (EDAX) experiments were carried out to characterize the single and bimetallic nanoparticles obtained. Cyclic voltammograms (CV) of clean nanoparticles were obtained after a controlled decontamination procedure of their surfaces. CO adsorption-oxidation and methanol electrooxidation were used as test reactions to check the electrocatalytic behaviour of the bimetallic nanoparticles. Pt 80Ru20 (nominal atomic composition) nanoparticles are the best electrocatalyst for both COad and methanol oxidation. All these results show that the microemulsion method can be used to produce bimetallic nanoparticles in a very easy way. The method can be very easily scaled-up for industrial use.

Related Products of 10049-08-8. Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 10049-08-8, Name is Ruthenium(III) chloride. In a document type is Article, introducing its new discovery.

The kinetics of Os(VIII) and Ru(III) catalysed oxidation of anti-pyretic drug, aspirin by diperiodatoargentate(III) (DPA) in alkaline medium at 298 K and a constant ionic strength of 0.10 mol dm-3 was studied spectrophotometrically. The oxidation products in both the cases are 1,4-benzoquinone2-carboxylate ion and Ag(I). The stoichiometry is the same in both the catalysed reactions i.e., [aspirin]:[DPA] = 1:2. The reaction is of first order in Os(VIII)/Ru(III) and [DPA] and has less than unit order in both [ASP] and [alkali]. The oxidation reaction in alkaline medium has been shown to proceed via a Os(VIII)/Ru(III)-aspirin complex, which further reacts with one molecule of DPA in a rate determining step followed by other fast steps to give the products. The main products were identified by spot test, IR, NMR and GC-MS. The reaction constants involved in the different steps of the mechanism are calculated. The catalytic constant (Kc) was also calculated for both catalysed reactions at different temperatures. From the plots of log K c versus 1/T, values of activation parameters with respect to the catalyst have been evaluated. The activation parameters with respect to slow step of the mechanism are computed and discussed and thermodynamic quantities are also determined. It has been observed that the catalytic efficiency for the present reaction is in the order of Os(VIII) > Ru(III). The probable active species of catalyst and oxidant have been identified.
