In a patent, introducing its new discovery.

A Ru-B amorphous alloy catalyst in the form of ultrafine particles was prepared by chemical reduction of RuCl3 with borohydride in aqueous solution, whose amorphous structure was confirmed by XRD, DSC, and SAED. Heating pretreatment resulted in the rapid crystallization and the deep decomposition of the Ru-B amorphous alloy as well as the abrupt decrease in the surface area due to the gathering of small particles at high temperature. XPS spectra revealed that partial electrons transferred from the alloying B to the metallic Ru in the as-prepared Ru-B sample. In comparison with other catalysts, the as-prepared Ru-B amorphous catalyst exhibited excellent activity and perfect selectivity to D-glucitol as well as superior lifetime during the liquid phase glucose hydrogenation, showing its potential application in industrial process. The higher activity of the Ru-based catalysts than that of other metal catalysts, such as Co-B and Ni-B amorphous catalysts as well as Raney Ni catalysts, demonstrated that the metallic Ru was more active than both metallic Ni and Co for the glucose hydrogenation. Meanwhile, the Ru-B amorphous catalyst exhibited higher activity than its corresponding crystallized Ru-B and pure Ru powder catalysts, showing the promoting effects of both the amorphous structure and the electronic interaction between the metallic Ru and the alloying B, which was briefly discussed based on the kinetic studies and various characterizations.

The syntheses of the water-soluble, chelating phosphines 1,2-bis(bis(hydroxybutyl)phosphino)ethane (1, n = 3; DHBuPE) and 1,2-bis(bis(hydroxypentyl)phosphino)ethane (1, n = 4; DHPePE) are reported. These ligands (and, in general, other 1,2-bis(bis(hydroxyalkyl)phosphino)ethane ligands) can be used to impart water solubility to metal complexes. As examples of this, the [Ni(DHPrPE)2Cl]Cl (2), [Rh(DHPrPE)2][Cl] (3), and [Ru(DHBuPE)2Cl2][Cl] (4) complexes were synthesized; they are indeed soluble in water (>0.5 M). Crystals of DHPrPE (1, n = 2) are monoclinic, space group P21/c, with a = 9.5935(8) A, b = 9.353(2) A, c = 10.655(2) A, alpha = 90, beta = 100.03(1), gamma = 90, V = 941.5(5) A3, R = 0.051, and Z 2. Crystals of [Ni(DHPrPE)2Cl]Cl (2) are monoclinic, space group 12, with a = 15.951(3) A, b = 11.454(2) A, c = 20.843(3) A, a = 90, beta= 91.24(2), gamma= 90, V = 3807(2) A3, R = 0.062, and Z = 4. Crystals of [Rh(DHPrPE)2][Cl] (3) are triclinic, space group P1, with a = 13.900(2) A, b = 15.378(2) A, c = 18.058(2) A, alpha = 87.71(1), beta= 75.03(1), gamma = 85.24(1), V = 3715(2) A3, R = 0.044, and Z = 4.

Three ruthenium(III) complexes containing 1H-1,2,4-triazole (Htrz), viz., (H2trz)[cis-RuCl4(Htrz)2], 1, (H 2trz)[trans-RuCl4(Htrz)2], 2, and (Ph 3PCH2Ph)[trans-RuCl4(Htrz)2], 3, have been synthesized by reaction between RuCl3 and excess of the triazole in 2.38 M HCl (1 and 2), while 3 was obtained by metathesis of 2 and [Ph3PCH2Ph]Cl in water. The products were characterized by IR, UV-vis, electrospray mass spectrometry, cyclic voltammetry, and X-ray crystallography (1 and 3). X-ray diffraction study revealed cis and trans arrangements of the triazole ligands in 1 and 3, correspondingly, and unprecedented monodentate coordination of the triazole through N2 and stabilization of its 4H tautomeric form, which is the disfavored one for the free triazole. The cytotoxicity of 1 and 2 has been assayed in three human carcinoma cell lines SW480, HT29 (colon carcinoma), and SK-BR-3 (mammary carcinoma). Both compounds exhibit antiproliferative activity in vitro. Time-dependent response of all three lines to 1 and 2 and a structure-activity relationship, i.e., higher activity of the trans-isomer 2 than that of cis-species 1, have been observed.

Voltammetric behavior of submicron-thick electrodeposited Pt-Ru on gold support is studied in sulfuric acid solution as a function of deposition potential and Pt:Ru ratio in chloride bath. In contrast to Pt-Ru, deposition of pure Ru is observed only at potentials of hydrogen evolution. The reason is found to be of kinetic nature, namely an inhibition of Ru deposition in presence of chloride. Chloride ions remain adsorbed on Ru at more negative potentials than on Pt and Au because of more negative ruthenium potential of zero free charge. Cu-UPD is applied to test the surface content of the oxidized Ru on pure Ru and various Pt-Ru surfaces. An enhancement of Ru oxohydroxides reduction in presence of Pt is observed. The electrocatalytic activity of Pt-Ru in respect to methanol oxidation correlates with the content of rechargeable surface Ru oxide. Ageing and ‘training’ of Pt-Ru electrodeposits under various modes is studied in order to determine the conditions of irreversible Ru oxidation. No manifestations of Ru dissolution from Pt-Ru electrodeposits in 0.5 M H2SO4 are found for anodic potential limits up to 1.1 V (RHE), in agreement with thermodynamic predictions. Electrodeposited Pt-Ru can be considered as a convenient model system for the study of Ru dissolution and crossover, as well as for determining the nature of the active surface species in the real composite catalysts for methanol oxidation.

The authors restrict this investigation to Ru/InP and Ru/GaInPAs contacts. The large grain polycrystalline quaternary semiconductor has been chosen because of differences in surface chemistry. Experimental data show that the typical current enhancement upon metallization is found. The increase in catalytic activity is larger for InP. A somewhat lower overall photoactivity is noted for GaInPAs.

The chemoselective hydrogenation of acetylacetone to 4-hydroxypentan-2-one over immobilized ruthenium phenanthroline metal complexes in amino functionalized MCM-41 in biphasic aqueous reaction medium was investigated. The catalyst was characterized by XRD, TEM, surface analysis, FT-IR and UV-vis to understand the morphology, complex geometry, and XPS such that the oxidation state of the metal complex inside the MCM-41 framework could be understood. The use of water as a solvent, not only gives high activity and selectivity for hydrogenation of acetylacetone, but also gives a path for an environmentally safer process. The optimizations of ligand, metal to ligand ratio, the choice of solvent and other reaction parameters were studied in detail. The heterogeneous catalytic system gave a higher degree of chemoselectivity (99%) towards 4-hydroxypentan-2-one as compared to homogeneous catalyst when hydrogenation was carried out using water as a solvent. The immobilized ruthenium-phenanthroline complex was easily separated and reused.

The catalytic activity of a film-type bismuth ruthenate electrode for oxygen evolution was greatly enhanced by the electrochemical pretreatment, including potential holding and cycling.On the other hand, any appreciable enhancement in catalytic activity was not observed for a pellet-type bismuth ruthenate electrode.Such an pretreatment effect was explained on the basis of the participation of higher valence Ru species in the oxygen evolution reaction, rather than the increase of surface area.
