d-metals are renowned for their superior electrocatalytic activity, attributed to their electronic structure. When alloys are formed with metals possessing both free and filled d-orbitals, a similar electronic structure is achieved. This phenomenon underpins the development of multicomponent alloys, which exhibit significantly enhanced functional properties, particularly in terms of electrocatalytic hydrogen evolution. Technical Electrochemistry of NTU "KhPI," focusing on the development of electrocatalytic alloys for the hydrogen evolution reaction. This research emphasis is linked to the longstanding tradition of galvanic coatings production and strong collaborations with various enterprises in Kharkiv. Concurrently, IFW-Dresden has been engaged in the development of glass or nanostructured alloys based on nickel, copper, magnesium, and other elements alloyed with yttrium, phosphorus, hafnium, cobalt, and palladium for hydrogen energy applications. Noteworthy advancements in this area include successful selective delegation techniques to achieve highly developed electrode surfaces. The collaboration between established scientific electrochemical schools in Germany and Ukraine is anticipated to foster a creative partnership, facilitating the resolution of challenges associated with green hydrogen in the future.
