We report the electrochemical deposition of lead (Pb) onto fluorine-doped tin oxide (FTO) electrodes in a sodium nitrate bath (0.4M NaNO3) at constant potential conditions. The kinetics electrodeposition processes have been in situ monitored for advanced nucleation stages by chronoamperometry for various temperature at fixed concentration of Pb2+, that is 0.1M. The microstructure and morphological characteristics of the deposit layers were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-Ray EDX techniques. The results show that the current density as well as the deposits density strongly depend on the temperature. The correlation between the experimental results and the theoretical process of the lead deposits was discussed and verified.
