Electrodeposition of Ge, Sn and GexSn1-x from two different room temperature ionic liquids

Abstract

In this paper, we present a simple and viable route for the synthesis of germanium-tin alloys (

Unique Structural Design and Strategies for Germanium‐Based Anode Materials Toward Enhanced Lithium Storage

“…The Raman spectra (shown in Figure b) further reveal the disordered nature of the carbon shells due to the relatively stronger intensity of the peak centred at 1333 cm −1 band compared to that of the peak at 1603 cm −1 , corresponding to the disorder‐induced D band and the graphitic G band, respectively. The peaks appearing at 174 cm −1 and 300 cm −1 can be related to the optical modes of metallic tin and germanium, respectively, which match well with previous reports in the literature …”

Tin, Bismuth, and Tin–Bismuth Alloy Electrodeposition from Chlorometalate Salts in Deep Eutectic Solvents

“…Studies of tin electrodeposited on gold electrodes from supercritical difluoromethane as well as from imidazolium‐ and pyrrolidinium‐based ionic liquids also revealed the formation of Au–Sn intermetallics. Such surface alloys were detected after deposition of as little as one monolayer of tin .…”

“…[13] Different crystallinep hases were identified by analyzing the coatings by X-ray diffraction, as presented in Figure 7. Besides bismuth (ICSD 53797), tin (ICSD 70128), and the gold substrate Studies of tin electrodepositedo ng old electrodes from supercritical difluoromethane [5] as well as from imidazolium- [11,58] and pyrrolidinium-based ionic liquids [59,60] also revealed the formation of Au-Sn intermetallics. Such surfacea lloys were detected after deposition of as little as one monolayer of tin.…”

Sn(TFSI)2as a suitable salt for the electrodeposition of nanostructured Cu6Sn5–Sn composites obtained on a Cu electrode in an ionic liquid

“…Electrodeposition of Sn has also been achieved from ILs mixture with AlCl3, 20,21 or ZnCl2, 22 or even in deep eutectic solvent. 23 Even if experimental deposition conditions modulate the morphology, the thickness, and the nanostructuration of the deposited layer, in this kind of synthesis, they are also dramatically influenced by the choice of the anion/cation combination of the IL 19,[24][25][26][27] Indeed the physicochemical properties of the solvent (conductivity, solubility, viscosity) impact the deposition potentials the and the electrodeposition mechanism. In the case of Sn deposit, some studies have already underline the influence of the anion 24,[26][27][28][29] through viscosity and stabilization of the precursor tin species from one part.…”

From another part, the influence of the ionic liquid cation through viscosity and likely its different adsorption /interactions with the substrate or the nuclei was also demonstrated [26][27][28] .…”
