Description

Report: 101 pages,. 1 volume, 62 figures, 14 tables, 116 references. Key words: electrocatalysis, electrocatalysts, electrochemically active complexes, electroreduction, functional electroplating technology. The work is to work out a theory of controlling electrodeposition kinetics for the goal-directed electrosynthesis of functional materials and promising electrolytes for the needs of electroplating technology and to create highly efficient stable electrocatalysts for the oxidation-reduction of hydrogen, oxidation of ethanol, reduction of molecular oxygen which contain no noble metals and have high specific characteristics, for electrochemical power sources and energy conversion. It has been found that the optimal variant for the formation of high-quality bifunctional coatings with molybdenum and tungsten alloys of iron triad metals is the polyligand complex salt electrolytes developed by us. Obtained nanocrystalline tungsten alloys of iron triad metals can replace in some cases platinum catalysts it have been found. It has been found obtained alloys can be arranged in the following order according to their electrocatalytic activity: Ni-W> Ni-Mo> Ni-Mo-P> Co-W> Co-Mo> Fe-W> Fe-Mo. Composition of nontoxic complexonate electrolytes and electrolysis conditions for the deposition of functional coatings for various purposes are proposed with allowance for the ionic composition of the electrolyte, mass transfer, and the composition of the electrochemically active complexes, energy characteristics, the kinetics and mechanism of electroreduction.
