Electrodeposition of Zn and Au–Zn alloys at low temperature in an ionic liquid

Abstract

In this communication, electrodeposition of Zn from 60-40 mol% ZnCl(2)-1-butyl-3-methylimidazolium chloride (BMIC) ionic liquid on Au substrates has been investigated. For the first time, initial stages of Zn electrocrystallization from BMIC has been studied by in situ X-ray diffraction (XRD) employing synchrotron radiation, which showed an initial epitaxial deposition of Zn and hexagonal Au(1.2)Zn(8.8) phases on Au(111) single crystal substrates. In the later stages of electrodeposition, phase analysis showed a formation of several Zn-Au intermetallics, namely AuZn, AuZn(3), and Au(1.2)Zn(8.8), along with the Zn phase.

Fabrication of superhydrophobic Au–Zn alloy surface on a zinc substrate for roll-down, self-cleaning and anti-corrosion properties

“…65-1849). These data accorded with the XRD results of Au-Zn alloys reported by Gotzmann 37 and Borissov 38 perfectly. The generation of oxide and intermetallic compounds via annealing treatment changed the surface chemical environment, resulting in the surface wettability transforming from superhydrophilicity to superhydrophobicity.…”

Lithiation and Delithiation Mechanisms of Gold Thin Film Model Anodes for Lithium Ion Batteries: Electrochemical Characterization

“…Au seed layers are furthermore employed for Si nano-wire growth for LIB Si anodes and Au is thus an integral part of the respective LIB anode [12]. Lithium (Li) as a small and reactive element diffuses readily in Au bulk materials (similar to Zn [13]), which has been recently employed to obtain Au-Li alloy precursors for further producing high-surface-area nanoporous gold (npg or npAu) by dealloying [14]. The dealloying approach has been early used to produce Raney Ni [15] or more recently dealloyed core-shell nanoparticles for catalysis [16].…”

Voltammetric Study and Electrodeposition of Zinc in Hydrophobic Room-Temperature Ionic Liquid 1-Butyl-1-methylpyrrolidinium Bis((trifluoromethyl)sulfonyl)imide ([BMP][TFSI]): A Comparison between Chloride and TFSI Salts of Zinc

“…Moreover, if aprotic ILs are used, hydrogen evolution, which is usually encountered in the electrodeposition of active metals such as Zn in aqueous solutions, can be significantly suppressed, leading to a more controllable surface morphology and higher current efficiency. Zn has been successfully electrodeposited from the traditional Lewis acidic ILs, [7][8][9][10] the air-and water-stable ILs, 3,[11][12][13][14][15][16][17][18][19] and DESs. [20][21][22][23] To search a common source of Zn ions and a suitable IL for the electrodeposition of Zn metal, however, is still important.…”
