Micromodification of nickel-based coatings electrodeposited from a deep eutectic solvent with lanthanum as a way to improve electrocatalytic performance and corrosion resistance
Electrodeposited nickel-based coatings microalloyed with lanthanum (up to approximately 1.75 wt%) were investigated. Electrodeposition was carried out using a deep eutectic solvent containing dissolved anhydrous salts of Ni(II) and Ce(III) as precursors. Electrochemical impedance spectroscopy results revealed that microalloying the chemical composition of coatings with lanthanum leads to a significant enhancement in electrocatalytic activity towards the hydrogen evolution reaction in an alkaline medium, as well as an improvement in corrosion resistance, compared to coatings not doped with lanthanum. These findings may be used in the development of high-performance electrocatalysts for hydrogen energy.
