Electrochemical formation multilayer coatings to create new effective electrocatalytic materials for electrolyzers for hydrogen production and protective coatings for harsh operating conditions with increased operational properties for hydrogen energy

popup.description2

Theoretical foundations for electrochemical formation of multilayer catalytic materials without using of precious or scarce metals for alkaline water electrolysis, stable during operation in conditions of fluctuations in power supply by renewable energy sources, are created. The influence of electrochemical formation conditions with stages of chemical and electrochemical dezincification of multilayer catalytic coating based on Cu-Ni-Zn alloys of different architectures on the mechanical stability of the developed surface, catalytic and corrosion properties has been determined. The kinetic parameters of the hydrogen evolution reaction on multilayer coatings of different architectures and layer compositions have been compared, new data have been obtained regarding the relationship between the periodic electrolysis mode and the architecture of multilayer structures with the catalytic, protective and operational properties of materials based on them, which will be used in the construction of multilayer coatings with specified properties. A method of accelerated testing of the operational properties of electrode materials in an alkaline environment has been developed, which simulates the influence of fluctuations in renewable energy in real conditions of electrode operation, and the stability of the catalytic multilayer electrode material under these conditions has been determined, and a method for its regeneration has been proposed. A new method of voltammetric determination of the chemical and phase composition of nano-sized films of alloys of the Cu-Ni-Zn system - components of protective multilayer coatings - has been developed, and the nature of changes in the chemical and phase composition of the layers-components of multilayer coatings depending on the conditions of electrolysis and the architecture of the coating has been determined: the corrosion properties of protective multilayer coatings under conditions of long-term operation have been determined, and new co
