| Abstract | This paper reports the electrodeposition of Pb, Te and PbTe films on Pt using ionic liquids based on choline chloride: ethylene glycol eutectic mixture (ChCl-EG, 1:2 moles) in the 45-65 0 C temperature range. Lead and tellurium ionic species were dissolved in ChCl:EG ionic liquid at concentrations in the range of 1-10mM. The mechanism of Te, Pb and PbTe electrodeposition was investigated by cyclic voltammetry and electrochemical impedance spectroscopy. The results indicated that the PbTe compound films were obtained by induced codeposition of Pb and Te onto the previously deposited Te on Pt substrate. Two or three dissolution (stripping) anodic peaks were observed by reversing the potential scanning. Nyquist and Bode impedance spectra show differences in Pt behavior due to its polarization at various cathodic potentials. |
