Electrodeposition of nickel had been successfully carried out for the first time in the ionic liquid triethylmethylammonium methyl sulphate (TEMAMS) on boron-doped diamond (BDD) along with glassy carbon electrode (GC). The electrochemical reduction of Ni (II) ions takes place slightly at a more positive potential on the BDD than the GC in this medium. The nickel deposition proceeds via three-dimensional instantaneous nucleation on the BDD and progressive on the GC. Surface morphologic characteristics of Ni deposits obtained on the BDD and GC at different deposition potentials were characterised by SEM and AFM. (C) 2013 Elsevier Ltd. All rights reserved.
