Influence of Manganese Ions on the Electrodeposition Process of Lead Dioxide in Lead Nitrate Solution

Resumo

The influence of manganese ions on the electrodeposition process of lead dioxide on the glassy carbon electrode (GCE) in the lead nitrate solution was investigated by cyclic voltammetry (CV), chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS). The results show that the electrodeposition process of lead dioxide was inhibited by the addition of manganese ions. However, the nucleation model is not influenced by the addition of manganese ions and the electrodeposition process still fits the instantaneous nucleation model with three-dimensional growth according to Scharifker—Hills’ model.
