“…It can also reduce the grain size of the deposits and improve the homogeneity and roughness of the deposited film 6 . Different complexing agents such as Copper Glo 31, 32 , EDTA 33 , citric acid 28 , and tri-sodium citrate 8, 12-15, 17, 26, 27, 34, 35 have been used in aqueous electrolyte solutions for electrodeposition of CZT films. Among them, tri-sodium citrate is the most widely used one because of its effective complexing abilities to Cu(II), Zn(II) and Sn(II) ions and its environmentally friendly nature 28,29 .…”

In this work, the effects of the concentrations of Cu (II), Zn (II) and Sn (II) ions in electrolytic bath solution on the properties of electrochemically deposited CuZnSn (CZT) films were investigated. The study of the composition of the CZT film has shown that the metallic content (relative atomic ratio) in the film increased linearly with the increase of the metal ion concentration. It is the first time that the relationship of the compositions of the alloy phases in the co-electrodeposited CZT film with the concentration of metal ions was revealed. The results have confirmed that the formantion and content of Cu6Sn5 and Cu5Zn8 alloy phases in the film were directly controlled by the concentration of Cu (II). SEM measurements have shown that Sn (II) had significant impacts on the film morphology which became more porous as a result of the bigger nucleation size of tin. The changes of surface properties of the films was also confirmed by chronoamperometry characteristic (i -t) deposition curve. By optimization of the metal ions concentrations in the electrolyte solution, a copperpoor and zinc-rich kesterite Cu2ZnSnS4 (CZTS) film was synthesized by sulfurization of the deposited CZT film. The solar cell with the CZTS film showed an energy conversion efficiency of 2.15% under the illumination intensity of 100 mW cm -2 .

“…6a, the powder I). 22,23 Considerable CuCl originates from the chloride-mediated reduction, while the Cu 2 O stems from the incomplete reduction of Cu 2+ to Cu + followed by the precipitation of Cu + as Cu 2 O. The formation of these unfavorable products leads to the low current efficiency of 32.5% and copper recovery of 42.9%.…”

Recovery of copper from hydrochloric acid solution is of significant importance for the heavy-metal pollution protection and valuable metal resources utilization. In order to overcome the drawbacks of low current efficiency and contaminated deposits in conventional electrochemical recovery, a controlled electrodeposition process was first developed using low-cost stainless steel cathodes. It has been demonstrated that mass transport has a facilitating effect for the copper electrodeposition in HCl media, thus a cylinder turbulent cell equipped larger surface area cathode was used. 93.6% copper was successfully extracted with a current efficiency of 89.4%, and the impurity of CuCl was completely eliminated. This indicated the low efficiency chloride-mediated pathway was avoided and the regular 2e reduction to metallic copper was greatly improved. Besides, more uniform and fine powder was obtained, which could be readily flushed and collected from the cell with water. This controlled electrodeposition may serve as a promising alternative to overcome the disadvantages of existing metal recovery and water purification.
