Effects of boric acid and water on the deposition of Ni/TiO2 composite coatings from deep eutectic solvent

Type III deep eutectic solvents (DES) have been extensively studied as a green electrodeposition solvent due to their wide potential window and degradability. The preparation of nickel-based coatings from DES commonly uses nickel chloride as the main precursor of Ni2+, but it generates harmful chlorides during long-term electrodeposition. This article uses nickel sulfate as the main precursor of Ni2+ to investigate the effects of boric acid and...
