The scientific direction of the controlled electrochemical deposition of nanostructured metals (Ag, Au, Pd) on the silicon surface by electrolysis and the method of galvanic substitution in the medium of organic aprotic solvents is developed. It is established that the combination of the pulsed mode of electrolysis and non-aqueous medium promotes the formation of metal nanoparticles. The effect of the concentration of reducing metal ions on the geometry of the nanoparticles and their distribution on the surface of the substrate were investigated. The dependence of the size of metal nanoparticles on the duration of the process of galvanic substitution was studied. The regularities of the influence of the process temperature, the type of silicon surface, the nature of organic solvents on the formation of nanostructured metal sediments (Ag, Au, Pd) and their morphology are revealed. Herefore, the value of cathode potentials, the duration of electrodeposition and the concentration of metal ions are the main factors influencing the morphology of the metal precipitate and the geometry of its structural particles, which is crucial for the controlled formation of nanostructures based on them. The complex of experimental data allowed to modify the silicon surface with metal nanoparticles to produce silicon nanostructures and plasmonically active surfaces based on them. The methods of pulsed electrolysis implemented in the work allow to obtain nanostructured sediments of metals of a given shape and size fixed on the substrate surface for the production of highly sensitive sensors with the subsequent conversion of sunlight into electrical energy. The dependence of geometry of nanoparticles of metals (Ag, Au, Pd) and sediment morphology on electrodeposition conditions (values of cathode potential, concentration of metal ions and process duration) are investigated. It is established that with increasing values of these values there is a tendency to form sediments from discrete particles (from 30 nm to 70 nm) to agglomerates (from 120 nm to 200 nm) and nanoporous films. It is established that the nature of the metal ion, its concentration, temperature and duration of the process of galvanic substitution are the main factors influencing the size of the deposited nanoparticles and the parameters of the controlled formation of Si/MNPs nanostructures. Nanoscale galvanic substitution of silver, palladium, and gold in organic aprotic solvents ensures the formation of nanostructured metal deposits on the silicon surface without the occurrence of side processes. This makes it possible to obtain Si/MNPs systems with nanoparticle sizes up to 100 nm with a relatively small size range. A schematic technological scheme of deposition of metal nanoparticles (Ag, Au, Pd) on silicon electroplating substitution in the environment of organic aprotic solvents was proposed, which allowed to obtain silicon/nanomaterial nanomaterials with functional properties. It has been found that Si/PdNPs, Si/AuNPs systems are more effective in forming silicon nanostructures than Si/AgNPs, due to the difference in metals by the values of standard electrode potentials. The scientific direction of the controlled electrochemical deposition of nanostructured metals (Ag, Au, Pd) on the silicon surface by electrolysis and the method of galvanic substitution in the medium of organic aprotic solvents is developed. It is established that the combination of the pulsed mode of electrolysis and non-aqueous medium promotes the formation of metal nanoparticles. The effect of the concentration of reducing metal ions on the geometry of nanoparticles and their distribution on the surface of the substrate were investigated. The dependence of the size of metal nanoparticles on the duration of the process of galvanic substitution was studied. The regularities of the influence of the process temperature, the type of silicon surface, the nature of organic solvents on the formation of nanostructured metals (Ag, Au, Pd) and their morphology are revealed. The feasibility of deposition of metal nanoparticles (Ag, Au, Pd) on the silicon surface is grounded, based on the high value of their standard electrode potentials and the efficiency of Si/MNPs systems in the formation of functional nanostructures and plasmonically active surfaces. The efficiency of combining the pulsed electrolysis regime and the environment of organic aprotic solvents for the controlled deposition of MNPs of a given geometry on a semiconductor surface is proved. The rational conditions for electrodeposition of nanostructured metals (Ag, Au, Pd) were experimentally established: the composition of the electrolyte, the pulse electrolysis parameters (cathode potential value, pulse duration and pauses) and the process duration (number of cycles). For E = -1,6 ...- 2,2 V from solutions (0,002 ... 0,008)M H[AuCl₄] + 0,05M Bu₄NClO₄ in DMSO; (0,001… 0,006)M Pd(NO₃)₂ + 0,05M Bu₄NClO₄ in DMSO and PC; (0,025… 0,1)M (NH₄)[Ag(CN)₂] in DMF, τon.:τoff. = 6: 300 ms, 25… 800 cycles, at a temperature of 25 °C silver, gold and palladium are deposited on the silicon surface to form nanoparticles. The dependence of geometry of nanoparticles of metals (Ag, Au, Pd) and sediment morphology on electrodeposition conditions (values of cathode potential, concentration of metal ions and process duration) are investigated. It is established that with increasing values of these values, there is a tendency to form sediments from discrete particles (from 30 nm to 70 nm) to agglomerates (from 120 nm to 200 nm) and nanoporous films. The conditions of controlled deposition of metal nanoparticles on a silicon surface according to their geometry are proposed. It is shown that within the cathodic potentials of -0,2 ... -2,5 V, solutions of reducing ions of a wide range of concentrations of silver, gold and palladium are deposited on the silicon surface in the form of discrete nanoparticles, which are uniformly distributed over the surface of the substrate. Therefore, due to the nature of the 3D semiconductor substrate, the growth of the recovered metal occurs by the Volmer-Weber mechanism. It is shown that in non-aqueous solutions of solvated and complex ions in the wide range of concentrations and temperatures on the silicon surface processes of nanosized galvanic substitution occur. The formation of the precipitate is carried out by the Volmer-Weber mechanism with the formation of discrete (islet) nanoparticles on a semiconductor substrate similarly to their deposition by electrolysis. High-donor molecules of organic aprotic solvent (L) due to donor-acceptor interaction L:→form surface complexes with fixed MNPs. The latter undergo a kind of "blocking", complicating their growth. This contributes to the formation of spherical MNPs due to the "smoothing" effect. It is established that the nature of the metal ion, its concentration, temperature and duration of the process of galvanic substitution are the main factors influencing the size of deposited nanoparticles and the parameters of the controlled formation of Si/MNPs nanostructures. Nanoscale galvanic substitution of silver, palladium, and gold in organic aprotic solvents ensures the formation of nanostructured metal deposits on the silicon surface without the occurrence of side processes. This makes it possible to obtain Si/MNPs systems with nanoparticle sizes up to 100 nm with a relatively small size range. The results of investigations, the use of electrochemically deposited metal nanoparticles (Ag, Au, Pd) on the silicon surface to create plasmonically active surfaces and silicon nanostructures are presented. The dependence of the morphology of the latter on the geometry of the nanoparticles deposited as activators of metal-active chemical etching. Si/PdNPs, Si/AuNPs systems have been found to be more effective in the formation of silicon nanostructures than Si/AgNPs. This is due to the difference of metals in the values of standard electrode potentials. The results of the research trials at the Research Center of the Committee of Forensic Expertise of the Republic of Belarus have shown the effectiveness of the materials obtained for highly sensitive sensors. Results of work in the educational process of the Department of Chemistry and Technology of Inorganic Substances of Lviv Polytechnic National University were introduced for specialized work 161 "Chemical technologies and engineering" specialization "Technical electrochemistry" in theoretical and laboratory classes in the discipline "Electrochemistry of nanomaterials".

This doctoral thesis is devoted to the development of scientific basics for electrochemical technologies used for the application of coatings consisting of ternary iron and cobalt alloys combined with molybdenum and tungsten of improved functionality. The hypothesis as for the competitive reduction of iron ternary metals with refractory components preconditioned by the mutual interaction of thermal-&-dynamic and crystal-&-chemical characteristics of the alloy-forming metals and the kinetic parameters of cathode process and it was proved experimentally. The kinetic regularities of the co-reduction in Fe³⁺ ‒ MoO₄²⁻ ‒ WO₄²⁻ ‒ Cit³⁻, Fe³⁺ ‒ Со²+ ‒ WO₄²⁻ (MoO₄²⁻) ‒ Cit³⁻ systems have been defined and the mechanism of deposition of ternary Fe-Mo-W, Fe-Co-W (Mo) alloys has been substantiated. The influence of composition of electrolytes and modes of electrolysis on elemental, phase composition and surface morphology of the obtained coatings has been deter-mined. The possibility of controlling the composition and morphology of multicomponent coatings on the basis of iron and cobalt by varying the composition of the electrolyte (the ratio of component concentrations, the ratio of ligand and complexing agent), and by used of galvanostatic and pulsed electrolysis regimes with a ranging of current density 2.5 ‒ 6.5 A/dm², and durations pulse/pause 5 ‒ 10 / 5 ‒ 20 ms, has been proved.

The thesis is devoted to the development of technology for iron alloys electrochemical functional coatings with molybdenum and tungsten electrodeposition from citrate electrolyte to produce materials with high corrosion resistance, physical, mechanical and tribological properties. On the basis of kinetic regularities the mechanism of Fe-Mo, Fe-Mo-W alloys’ formation was established as co-precipitation of iron with molybdenum and tungsten in the range pH 3,0–4,0 happening on two routes, one-alloying metals reduction from heteronuclear complexes [FeHCitMO₄]⁻ is accompanied by chemical reaction of ligand releasing, and the second-reduction of iron (III) from the adsorbed complexes [FeHCit]⁺ and in part – from FeOH²⁺ accompanied by the chemical stage of ligand release. Experimental study of the electrolytic alloys functional properties have shown the high corrosion resistance of FeMo and Fe-Mo-W coatings in acidic and neutral media stimulated by acidic nature of refractory oxide components which exceeds the resistance of steel and cast iron. Proposed electrolytic alloys dominated by microhardness steel substrates in 2–3 times, and cast iron – in 4–5 times, the increasing tungsten content provides increasing in physical, mechanical and tribological properties of electrolytic alloys due to the formation of amorphous structure. A technological scheme for electrochemical synthesis of iron alloys functional coatings with molybdenum and tungsten was designed and technological instructions were prepared for implementation.

The dissertation is devoted to the development of technology for electrodeposition of functional coatings by alloys of iron with cobalt and molybdenum from complex citrate electrolytes. Based on the analysis of ionic equilibria and kinetic laws, it was found that molybdenum is converted into an alloy with iron and cobalt to a metallic state from heteronuclear complexes through the formation of intermediate spokes both as a result of cathodic polarization and as a result of the formation of hydrogen and hydrogen atoms. realize overflow effect. Changing the modes and parameters of electrolysis allows the formation of composite metal oxide coatings in iron-cobalt-molybdenum system by including a metal matrix of molybdenum oxide as an intermediate link of electrode reactions. The quantitative composition of the electrolyte and the modes of coating with a given content of components, morphology, structure and operational characteristics are justified. The optimal polarization modes are determined, the use of which allows one to obtain defect-free coatings. The corrosion resistance of the coatings of the Fe-Co-Mo(MoOₓ) system exceeds the value for the alloy components, and the microhardness is three times higher than the microhardness for steel and individual components of the ternary system. High electrocatalytic activity of the coatings was found in cathodic hydrogen evolution reactions, which, as a result of the synergistic effect, is higher than for individual metals, and grows with the molybdenum content and the activity of Fe-Co-Mo (MoOₓ). Coatings in the reactions of anodic oxidation of low molecular weight alcohols at a current density of the anodic and cathodic peaks are even higher than on a platinum electrode. The coatings turned out to be "soft magnetic materials" that can be used in the manufacture of magneto-optical information storage devices, and the sensory properties of individual components of gaseous media were used to create a sensitive element of the sensor. The technological scheme of electrodeposition of Fe-Co-Mo (MoOₓ) coatings is proposed, depending on their practical purpose.

The component composition of the electrolyte and the ratio of the concentrations of the alloys forming components in the ferum-cobalt-molybdenum system and the regularities of the complex formation in the presence of citrate, which became the basis for the development of electrolytes for metal deposition and metal oxide coatings are substantiated. It was found that high-quality coatings with a molybdenum content of more than 30 at.% Are formed from electrolytes with a concentration of sodium citrate of 0,4 – 0,5 М and oxometalate of 0,2 М. It is proved that the formation of heteronuclear complexes is a prerequisite for the flexible control of ionic equilibria in solution, the mechanism and overvoltage of electrode reactions, the course of which obeys the laws of mixed kinetics, which is confirmed and determined by the activation energy of the process. The reduction of the molybdate ion to the metal phase occurs by the formation of surface oxides of an intermediate oxidation state. Depending on the completeness of the course of this process, conditions are created for the formation of a metal coating of a ternary alloy or a metal oxide composite, the second phase of which consists of molybdenum oxides in an intermediate oxidation state, that is, is formed directly in the electrolysis process. The reduction of oxometalate can occur in several stages using both the electrochemical and chemical mechanisms, which include hydrogen ad-atoms and atoms that are formed in the cathodic reaction. It is this feature that provides the variability of the cathode process and allows flexible control of the stages, as well as the composition and properties of the product of the technological process. The main factors ensuring variability of the coating composition are polarization modes — galvanostatic and pulsed modes, and amplitude and time parameters of the current. At the same current densities, the use of pulsed electrolysis allows the formation of coatings with a significantly higher molybdenum content. In particular, with a constant pulse duration of 10–20 ms and pauses of 5–20 ms, the composition of the shells is enriched in molybdenum to 30 at.% With a significantly lower oxide content. Such changes in the composition of the coating compared with the stationary regime are due to the chemical reaction of the reduction of intermediate molybdenum oxides by hydrogen atoms as a result of the overflow effect. The higher content of the oxide phase in the composition of tournament alloys formed in the galvanostatic mode allows us to classify them as composites. With the same polarization mode, the parameters depending on the current are determined not only by the content of the components of the alloy or composite, but also by the morphology of the coating surface and the current efficiency. Under the conditions of stationary electrolysis, the efficiency of the alloy is in the range 56−62 %, and when using pulsed electrolysis, the efficiency of the process increases to 61–70 % due to the chemical reaction of the reduction of molybdenum oxides. hydrogen atoms of hydrogen. The dissipated ability of the electrolyte also depends on the current density and is extreme in nature with a maximum of 62% at i = 2.5 A/dm². Dissipation results are consistent with known electrolytes. Composite coatings Fe−Co−MoOₓ and metallic coatings Fe−Co−Mo have a fine-crystalline structure, surface development increases with increasing current density, and the nature and size of crystallites depends on the composition of the coatings and electrolysis conditions. So for Fe48Co40Mo12 coatings obtained by direct current, the average crystallite size is 63 Ǻ, and for Fe43Co39Mo18 coatings obtained in a pulsed mode, the average crystallite size is 56 Ǻ. Depending on the electrodeposition modes, the surface roughness also varies - in the galvanostatic and pulsed modes, the parameter Ra for the alloys is 0,15 and 0,11, respectively, which corresponds to grades 9-10. The synthesized coatings have a range of physico-chemical and physico-mechanical properties with a high level of performance. Thus, corrosion resistance testing shows that the depth of the index (0,018 – 0,02 mm/year) coatings are characterized as 4 points of resistance on a ten-point scale, and ranked according to the density of the corrosion current is "stable" in acidic solutions and "very stable" in neutral and alkaline solutions. Corrosion resistance to the acid solutions increases the presence of molybdenum through the acidic nature of its oxides, and in neutral and alkaline solutions the covers exhibit resistance due to passivation of iron and cobalt. The free energy of the surface of metal coatings and composites is in the range of 118-128 mJ/m², which is almost an order of magnitude lower than the alloys of the component and the surfaces of the Fe−Co−MoOₓ composites lower than the Fe−Co−Mo alloy due to the higher oxygen content in its structure. , causing the composites to be chemically stable. The microhardness of galvanic coatings is in the range of 595–630 kgf/mm² depending on the individual components and is 2,5–3 times higher than for steel. The microhardness of the coatings increases symbatically with an increase in the amount of molybdenum in the alloy and also increases with an increase in this parameter in the integral of current densities. The high adhesion of the coatings to the surface of the steel, resistance to polishing, heating and kink is established. The high electrocatalytic activity of ternary alloys in the reactions of anodic oxidation of low molecular weight alcohols was established, and the magnitude of the peaks of the anodic and cathodic currents in the cyclic voltammogram is even higher than that of the platinum electrode, so galvanic coatings with Fe−Co−Mo alloy can be considered a promising catalytic material for fuel cells. High electrocatalytic activity of the skin was also detected in cathodic reactions of hydrogen evolution from alkaline and acidic media, which is higher as a result of the synergistic effect compared to individual metals. A connection was established between the alloy composition and catalytic properties – a higher molybdenum content usually improves the quality of coatings. At the same time, the exchange current density of the hydrogen evolution reaction on composite coatings in all model solutions is higher than for metal coatings, which is consistent with the results of determining the current efficiency. The coatings have magnetic properties, and the value of the coercive force for Fe—Co−Mo coatings is in the range of 7-10 Oe, which is higher than the value for the Fe−Co alloy (6,5-7,2 Oe). Fe−Co−Mo alloys are "Magnetic materials" and can be used in the production of magnetic information storage elements. The alloy has sensory properties on the individual components of the gas environment and can be used, in particular, as a sensor material of the sensor to determine the maximum hydrogen concentration. Based on kinetic characteristics and technological parameters, software and technological module have been created and a variable technological scheme for applying Fe−Co−Mo(MoOₓ) coatings of controlled composition and predicted physicomechanical and physicochemical properties has been proposed. According to the results of tests and elements of equipment coated with ternary alloys at PJSC "Ukrndikhimmash" and at the Metrological center of military standards of the Armed Forces of Ukraine, a high level of operational characteristics of the synthesized coatings and the effectiveness of the technology for their synthesis have been proved. The research results were introduced into the educational process of the Department of Physical Chemistry NTU "KhPI" and the Military Institute of Tank Troops NTU "KhPI".
