Pb electrodeposition from PbO in the urea/1-ethyl-3-methylimidazolium chloride at room temperature

Abstract

In this study, we dissolved PbO in a new electrolyte urea/1-ethyl-3-methylimidazolium chloride (EMIC) and electrochemically extracted Pb.

Lead (Pb) interfacing with epitaxial graphene

“…It can be seen that the experimental curves for electrodeposition of metallic Pb on Gr/SiC show the best agreement with the dependence computed in the frame of the instantaneous nucleation mechanism, which is consistent with Pb electrodeposition mechanisms reported for copper, 52 silicon surface 51 and tungsten foil. 53 Further data analysis in the frame of eqn (2) and (3) showed an exponential increase of the number of active nucleation sites (N 0 ) on Gr/SiC (Fig. 8d), which is typical for an instantaneous nucleation mechanism.…”

Electrodeposition of Copper Metal from the 1-Ethyl-3-methylimidazolium Fluoride ([EMIM]F)-urea-H₂O System Containing Cu₂O

“…Urea, Cu 2 O, and Tungsten substrate were purchased and used according to the procedure earlier described. 30 Also, urea and [EMIM]F were mixed in a molar ratio of 2:1 and then were used to dissolve 1.30 mmol Cu 2 O. This final mixture was labeled as…”

“…Cu extraction and electrochemical investigation in this system were carried out according to the procedure reported in previous literature. 30 A tungsten wire (0.05 cm in diameter) was used as the working electrode (WE), a platinum wire (0.05 cm in diameter) and silver wire (0.05 cm in diameter) were used as the counter electrode (CE) and the quasi-reference electrode (QRE), respectively. 30 All the electrodes were sanded with sandpaper, ultrasonically degreased in an ethanol solution, and then washed with deionized water before use.…”
