Документ Functional coatings by ternary cobalt based alloys for the autumobile industry(Харківський національний автомобільно-дорожній університет, 2015) Nenastina, T. O.; Hapon, Yu. K.; Glushkova, M. A.; Sakhnenko, N. D.; Ved, M. V.The environmentally friendly and resource-saving technologies for producing multifunctional coatings based on cobalt and silver alloys with refractory metals are proposed. The catalytic activity testing results of binary and ternary alloys based on cobalt in the carbon monoxide oxidation reaction in carbon dioxide were analyzed. It was revealed that there is on improvement of functional properties of galvanic alloys when the content of tungsten and molybdenum is within the range of 10–30 wt. %.Документ Catalytic properties of binary and ternary alloys based on silver(Науково-технологічний комплекс «Інститут монокристалів» Національної академії наук України, 2013) Ved, M. V.; Glushkova, M. A.; Sakhnenko, N. D.The correlation between the morphology, composition and catalytic properties of silver-cobalt alloys has been shown. The galvanic Ag-Co alloy is established as synergetic ones, and the values obtained for the exchange current density of the model hydrogen evolution reaction are similar to platinum. The catalytic activity testing results of binary (Ag-Co) and ternary (Ag-Co-Zr, Ag-Co-Bi) alloys in the carbon monoxide oxidation to carbon dioxide were analyzed.Документ Electrodeposited cobalt alloys as materials for energy technology(Cambridge University Press, 2013) Glushkova, M. A.; Bairachna, T.; Ved, M. V.; Sakhnenko, N. D.The influence of electrodeposition parameters on chemical composition, morphology and functional properties of such binary cobalt alloys as CoAg, CoW, and CoFe has been investigated. The alloys are shown to possess catalytic properties. Catalytic actuvity was preliminary estimated in the electrolytic hydrogen evolution reaction and tested by CO to CO2 conversion during the catalytic benzene oxidation.Документ Nanostructured cobalt and iron electrodeposited alloys(Springer Science+Business Media, Inc., 2014) Ved, M. V.; Sakhnenko, N. D.; Glushkova, M. A.; Karakurkchi, A. V.Документ Electrodeposition of catalytic ternary cobalt based coatings(Украинский государственный химико-технологический университет, 2015) Ved, M. V.; Sakhnenko, N. D.; Glushkova, M. A.; Hapon, Yu. K.; Kozyar, M. A.Consistent patterns for electrodeposition of Co-Mo-W and Co-Mo-Zr coatings from polyligand citrate-pyrophosphate bath were investigated. The effect of both current density amplitude and pulse on/off time on the quality, composition and surface topography of the galvanic alloys were determined. It was established the coating Co-Mo-Zr enrichment by alloying components with current density increasing as well as the rising of pulse time promotes the content of zirconium, and pause – molybdenum because of subsequent chemical reduction of its intermediate oxides by hydrogen ad-atoms. It was found that the content of the refractory metals in the coating Co-Mo-W depends on the current density and on/off times extremely and maximum Mo and W content corresponds to the current density interval 12–18 A·dm−2, on-/off-time 5–10 msec. It was shown that Co-Mo-W alloys exhibits the greatest level of catalytic properties as cathode material for hydrogen electrolytic production from acidic media which is not inferior a platinum electrode. The galvanic alloys Co-Mo-Zr with zirconium content 1.5–2.0 wt.% demonstrate high catalytic properties in the carbon oxide (II) oxidation. This confirms the efficiency of materials as catalysts for the gaseous wastes purification and gives the reason to recommend them as catalysts for hydrocarbon combustion.
