Pt and Pt-Ru alloys with several Pt/Ru ratios supported on carbon (Vulcan) were prepared using high-intensity ultrasound by reduction of H2PtCl6 and RuCl3 precursors in an aqueous solution. This method of catalyst preparation was performed in absence of any surfactant or organic addictive. The particles formed were characterized by X-ray diffraction (XRD), energy dispersive X-ray (EDX) and transmission electron microscopy (TEM). From the XRD studies, a decrease of metal particle size and of the lattice parameters was observed with the increase of the Ru content. The electroactivities were tested for the methanol oxidation reaction in acid electrolyte, and it was found that Pt-Ru catalysts were more activity than pure Pt.

We have investigated the electrochemical, spectroscopic, and electroluminescent properties of a family of diimine complexes of Ru featuring various aliphatic side chains as well as a more extended pi-conjugated system. The performance of solid-state electroluminescent devices fabricated from these complexes using indium tin oxide (ITO) and gold contacts appears to be dominated by ionic space charge effects. Their electroluminescence efficiency was limited by the photoluminescence efficiency of the Ru films and not by charge injection from the contacts. The incorporation of di-tert-butyl side chains on the dipyridyl ligand was found to be the most beneficial substitution in terms of reducing self-quenching of luminescence.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 10049-08-8 is helpful to your research., Reference of 10049-08-8

Kotalanol and de-O-sulfonated-kotalanol are the most active principles in the aqueous extracts of Salacia reticulata which are traditionally used in India, Sri Lanka, and Thailand for the treatment of diabetes. We report here the exact stereochemical structures of these two compounds by synthesis and comparison of their physical data to those of the corresponding natural compounds. The candidate structures were based on our recent report on the synthesis of analogues and also the structure-activity relationship studies of lower homologues. The initial synthetic strategyrelied on the selective nucleophilic attack of p-methoxybenzyl (PMB)-pr otected 4-thio-D-arabinitol at the least hindered carbon atom of two different, selectively protected 1,3-cyclic sulfates to afford the sulfonium sulfates. The protecting groups consisted of a methylene acetal, in the form of a seven-membered ring, and benzyl ethers. Deprotection of the adducts yielded the sulfonium ions but also resulted in de-O-sulfonation. Comparison of the physical data of the two adducts to those reported for de-O-sulfonated natural kotalanol yielded the elusive structure of kotalanol by inference. The side chain of this compound was determined to be another naturally occurring heptitol, D-perseitol (D-glycero-D-galacto-heptitol) with a sulfonyloxy group at the C-5 position. The synthesis of kotalanol itself was then achieved by coupling PMB-protected 4-thio-D-arabinitol with a cyclic sulfate that was synthesized from the naturally occurring D-perseitol. The work establishes unambiguously the structures of two natural products, namely, kotalanol and de-O-sulfonated kotalanol.

It is well-known that platinum/ruthenium fuel cell catalysts show enhanced CO tolerance compared to pure platinum electrodes, but the reasons are still being debated. We have combined cyclic voltammetry (CV), temperature programmed desorption (TPD), electrochemical nuclear magnetic resonance, and radio active labeling to probe the origin of the ruthenium enhancement in Pt electrodes modified through Ru deposition. The results prove that the addition of ruthenium not only modifies the electronic structure of all the platinum atoms but also leads to the creation of a new form of adsorbed CO. This new form of CO may be ascribed to CO chemisorbed onto the “Ru” region of the electrode surface. TPD and CV results show that the binding of hydrogen is substantially modified due to the presence of Ru. Surprisingly though, TPD indicates that the binding energy of CO on platinum is only weakly affected. Therefore, the changes in the bond energy of CO due to the ligand effect only play a small role in enhancing CO tolerance. Instead, we find that the main effect of ruthenium is to activate water to form OH. Quantitative estimates based on the TPD data indicate that the bifunctional mechanism is about four times larger than the ligand effect.

The instability of the commonly adopted support (e.g., Ti, Ti-Pd alloys, Ta) for the preparation and characterization of different electrode materials has been overcome by depositing the electrode material of interest (RuO2) on conductive, boron-doped diamond (BDD). The present paper reports results on the model chlorine evolution reaction, investigated at BDD surfaces modified by RuO2 loadings of 1.2 A¿ 1013, 6.0 A¿ 1014, and 2.65 A¿ 1016 molecules cm-2. A radical spillover mechanism is proposed for the reaction occurring at the electrode having the lowest noble-metal oxide loading.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of Ruthenium(III) chloride, you can also check out more blogs about10049-08-8

Electric Literature 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.

This work investigates the feasibility of thermal and catalytic cyclization of 6,6-disubstituted 3,5-dien-1-ynes via a 1,7-hydrogen shift. Our strategy began with an understanding of a structural correlation of 3,5-dien-1-ynes with their thermal cyclization efficiency. Thermal cyclization proceeded only with 3,5-dien-1-ynes bearing an electron-withdrawing C(1)-phenyl or C(6)-carbonyl substituent, but the efficiencies were generally low (20-40% yields). On the basis of this structure-activity relationship, we conclude that such a [1,7]-hydrogen shift is characterized by a “protonic” hydrogen shift, which should be catalyzed by pi-alkyne activators. We prepared various 6,6-disubstituted 3,5-dien-1-ynes bearing either a phenyl or a carbonyl group, and we found their thermal cyclizations to be greatly enhanced by RuCl 3, PtCl2, and TpRuPPh3(CH3CN) 2PF6 catalysts to confirm our hypothesis: the C(7)-H acidity of 3,5-dien-1-ynes is crucial for thermal cyclization. To achieve the atom economy, we have developed a tandem aldol condensation-dehydration and aromatization catalysis between cycloalkanones and special 3-en-1-yn-5-als using the weakly acidic catalyst CpRu(PPh3)2Cl, which provided complex 1-indanones and alpha-tetralones with yields exceeding 65% in most cases. The deuterium-labeling experiments reveal two operable pathways for the metal-catalyzed [1,7]-hydrogen shift of 3,5-dien-1-ynes. Formation of alpha-tetralones d4-56 arises from a concerted [1,7]-hydrogen shift, whereas benzene derivative d4-9 proceeds through a proton dissociation and reprotonation process.

Disodium[hydroxotetranitronitrosyl]ruthenate(II) is a photochromic compound excitable with blue-green light which exhibits at least one unusually long-lived metastable state at low temperature. At 298 K, the compound crystallises in the space group C2/m. A reversible phase transition occurs at 240 K upon cooling, as detected by Differential Scanning Calorimetry and X-ray powder diffraction which causes a lowering of the crystal symmetry to the space group P21/n. Synchrotron X-ray single crystal diffraction and FT-IR spectroscopy data obtained on the ground and the excited states of the title compound low temperature phase are presented.

Pristine Li4Ti5O12 (LTO) and Ru-doped Li4Ti5O12 with the composition of Li 4Ti4.95Ru0.05O12 (Ru-doped LTO) are synthesized by solid-state reaction. Ru doping into the lattice of LTO affects the electronic structure of LTO, leading to the modification of optical properties and improvement in electrochemical performance. The variations between pristine LTO and Ru-doped LTO in optical properties are investigated by UV-vis and Raman spectroscopy. In addition, the related microstructure is characterized by XRD, SEM and TEM. The enhancement in electronic conductivity of Ru-doped LTO can provide the discharge capacities of 222, 183 and 132 mAh/g at 1C, 5C and 10C, respectively, during the voltage window of 0.01-2.5 V. Furthermore, the capacity retentions are 95, 92 and 86% for 1C, 5C and 10C rates, respectively, at 100th cycles. The significant improvement in electrochemical performance demonstrates that ruthenium doped lithium titanate is promising as a high rate anode for lithium ion batteries.
