Nickel Electrodeposition from Protic Ionic Liquids Based on Carboxylate Anions as Electrolyte: I. Electrodeposition from 2-hydroxyethyl Ammonium Formate.

摘要

Ni electrodeposition from a protic ionic liquid based on carboxylated anions, 2-hydroxyethylammonium formate (2HEAF), was studied in order to evaluate the feasibility to obtain deposits withwell-controlled properties and also to determine the influence of the electrodeposition conditions onthese properties. Results show that nickel is electrodeposited from this non-aqueous medium followingan instantaneous nucleation mechanism as a pure, compact and uniform deposit, composed ofnanocrystallites with size ranging from 18 nm to 23 nm, without the use of additives or tensioactiveagents, contrary to what is required to obtain similar deposits from aqueous electrolytes.
