Abstract

Anodic electrochemical treatment of nickel-copper alloy (45 wt.% Ni) was conducted in a deep eutectic solvent, ethaline (a eutectic mixture of choline chloride and ethylene glycol). The electrochemical behavior of the Ni–Cu alloy was investigated by means of linear voltammetry technique. Anodic treatment of nickel-copper alloy in ethaline was stated to enhance the electrocatalytic activity towards hydrogen evolution reaction in alkaline water electrolysis. The results obtained can be used to develop new electrocatalysts for hydrogen synthesis in hydrogen energy.
