Electrodeposition of nickel from dimethyl sulphoxide bath:Effect of nucleoside

摘要

Dimethylsulphoxide (DMSO) may act as a potent medium for electrodeposition of Ni in presence of nucleosides.Totally bright electroplate may result from NiAc+NiSO4+NiSMT/DMSO bath in presence of trace amount of nucleoside (ribocytine/deoxycitidine).Too many coordinating centers of nucleoside facilitate the release of Ni from [Ni(DMSO)_6]~(3+) complex in the vicinity of catholite causing outwardly growth more dominant than lateral growth,resulting in bright,adherent,Ni electrodeposite.
