Ionic Liquids (ILs) are a new kind of solvents that can be used as alternative solvents in order to improve the chemical or environmental performances of aqueous electrodeposition processes, commonly based on the use of hazardous chemicals. In this work we study the feasibility to use 2-hydroxyethyl ammonium propionate as solvent for the electrodeposition of nickel. Results shown that in this reaction medium, it is possible to obtain pure and homogeneous deposits of nanocrystalline nickel. These deposits grow with an initial 3D- and after following a 2D-mechanism, with a roughness and crystal size, dependent on the electrodeposition conditions.
