Electrodeposition of tin and antimony in 1-ethyl- 3-methylimidazolium tetrafluoroborate ionic liquid

Abstract

The electrodepositions of Sn(II) and Sb (III) were studied in the [EMIm]BF 4 ionic liquid at ambient temperature. Linear sweep voltammetry (LSV) results indicated that the reductions of Sn(II) and Sb(III) on Pt electrode are electrochemically irreversible. The diffusion coefficients of Sn(II) and Sb(III) in the ionic liquid electrolyte were determined in terms of the LSV data. Tin and antimony ions form simpler Sn(II) chlorocomplex species and higher Sb(III) chlorocomplexes, respectively present in the ionic liquid electrolyte. Energy dispersive X-ray spectroscopy (EDX) analysis revealed that tin and antimony alloys can be electroplated in the ionic liquid electrolyte.

Diffusion Coefficient of Tin(II) Methanesulfonate in Ionic Liquid and Methane Sulfonic Acid (MSA) Solvent

“…It can be suggested that the complexation between the Tin(II) with trifluoromethylsulfonate and trifluoromethylsulfonyl imide, which is larger than the chloride ion and the tetrafluoroborate ion, has increased the radius of the Tin(II) species in solution. This contributes to the lower diffusion coefficient compared with the chloride and tetrafluoroborate based ionic liquids from the works of Hussey and Xe [6] and Yang et al [7] It can also be said that the diffusion coefficient from this work using trifluoromethylsulfonate ionic liquid has a greater value compared with the trifluoromethylsulfonyl imide, [8] which is in accordance with larger dynamic radius of the trifluoromethylsulfonyl imide ionic liquid compared with the trifluoromethylsulfonate ionic liquid.…”

“…Yang et al [7] used tetrafluoroborate, BF 4 À -based ionic liquid, where the diffusion coefficient was higher than calculated from the chloroaluminate ionic liquid by Hussey and Xe. [6] It can observed that the smaller Tin(II) tetrafluoroborate species will contribute to a slightly higher diffusion coefficient value for the Tin(II) species.…”

“…[4,5] Among the studies carried out on the electrodeposition of Tin(II) in ionic liquids includes the publication by Hussey and Xe, [6] who used AlCl 3 mixed in a 1-methly-3-ethyl imidazolium chloride melt. Later, Yang et al [7] reported the alloy electrodeposition of tin and antimony in 1-ethyl-3-methylimidazolium tetrafluoroborate, and Tachikawa et al [8] reported the electrodeposition of Tin(II) using a hydrophobic ionic liquid, 1-n-butyl-1-methylpyrrolidinium bis (trifluoromethylsulfonyl) imide.…”

Electrochemical and transport properties of ethaline containing copper and tin chloride

“…The position of current maxima in the forward and reverse sweep varied with scan rate, which shows a quasi reversible or irreversible process for Sn. 28,29 The diffusion coefficient of Cu was determined using the Randles-Sevčik equation for reversible couples using the peak appearing at (0?45 V/0?35 V). According to Randles-Sevčik 30…”

The Thermodynamic Estimation and Viscosity, Electrical Conductivity Characteristics of 1-Alkyl-3-Methylimidazolium Thiocyanate Ionic Liquids

“…The study of the effect of various functional cations/anions on ILs has been a hot topic [4][5][6][7][8][9]. Moreover, the dialkylimidazolium-based ILs with thiocyanate (SCN) anion have attracted significant attention because of their low dynamic viscosities [10,11].…”
