AB  - Preparation of RuOxHy/carbon black nanocomposite material was performed by the impregnation method starting from RuOxHy sol as a precursor. Black Pearls 2000® (BP) and Vulcan® XC-72 R (XC) were used as supporting materials. Samples of the composite were calcined in nitrogen atmosphere at temperatures from 130 to 450 °C. Chemical and structural characterization of the precursor and the composites was performed by using energy-dispersive X-ray fluorescence spectroscopy (EDXRFS), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). These techniques showed that the oxide impregnated into carbon support is hydrous and amorphous. The amorphous structure is maintained if the composite is calcined up to 300 °C, while the low-intensity peak at 2θ position that corresponds to the most intensive peak of the rutile structure was registered at 450 °C. The capacitance of the composite was determined using cyclic voltammetry. It was found that the capacitance is dependent on calcination temperature and surface area of the carbon black support. The highest specific capacitance of about 700 F g−1 of composite was registered for RuOxHy supported on BP and calcined at 300 °C while four times lower values was obtained for RuOxHy supported on XC. The capacitance measurements indicated that XC-supported RuOxHy composite is highly porous while BP-supported one is more compact.

AB  - Spontaneous deposition of ruthenium on Au(1 1 1) surfaces from 1.0 mM RuCl3 + 0.5 M H2SO4 (or 0.1 M HClO4) solutions was investigated by in situ STM and cyclic voltammetry, focusing on the morphology of the resulting submonolayer Ru modified surfaces. STM results show a pronounced step decoration, indicating that the steps are active sites for the nucleation of Ru monolayer islands, while a random distribution of Ru nuclei is observed on terraces. During deposition, the open circuit potential rapidly increases from 0.38 to above 0.72 V vs. (Ag/AgCl). Experiments with different deposition times show that deposition from sulfuric acid solution saturates after 3 min deposition, the island size reaches its saturation value of 2.8 nm after 1 min. Significantly higher deposition activities and saturation coverages are found for deposition from perchlorate solution and for deposition on highly stepped surfaces/surface areas, indicative of a pronounced anion effect and reflecting the higher activity of steps for Ru deposition, respectively. In both cases, in particular for deposition in perchlorate solution, islands grow to multilayer heights and assume hexagonal shapes. Finally it is shown that multiple deposition can be utilized to reach higher coverages, attaining step saturation also in sulfuric acid solution. The Ru modified Au(1 1 1) electrode was found to be inert for hydrogen adsorption, and the electrochemical results indicate that the ruthenium islands inhibit long-range ordering of the sulfate adlayer on the substrate.
