Abstract

The electrodeposition of tin, bismuth, and tin-bismuth alloys from Sn(II) and Bi(III) chlorometalate salts in the choline chloride/ethylene glycol (1:2 molar ratio) deep eutectic solvent was studied on glassy carbon and gold by cyclic voltammetry, rotating disc voltammetry, and chronoamperometry. The Sn(II)-containing electrolyte showed one voltammetric redox process corresponding to Sn(II)/Sn(0). The diffusion coefficient of [SnCl3](-), detected as the dominating species by Raman spectroscopy, was determined from Levich and Cottrell analyses. The Bi(III)-containing electrolyte showed two voltammetric reduction processes, both attributed to Bi(III)/Bi(0). Dimensionless current/time transients revealed that the electrodeposition of both Sn and Bi on glassy carbon proceeded by 3D-progressive nucleation at a low overpotential and changed to instantaneous at higher overpotentials. The nucleation rate of Bi on glassy carbon was considerably smaller than that of Sn. Elemental Sn and Bi were electrodeposited on Au-coated glass slides from their respective salt solutions, as were Sn-Bi alloys from a 2:1 Sn(II)/Bi(III) solution. The biphasic Sn-Bi alloys changed from a Bi-rich composition to a Sn-rich composition by making the deposition potential more negative.
