Preparation and characterization of the novel Ti/PbO_2 electrodes by electrodeposition and anodization

摘要

The novel Ti/PbO_2 electrodes have been prepared by electrodeposition and anodization. The electrodes were characterized by SEM, XRD and linear sweep voltammetry (LSV). The SEM and XRD analysis reveal that Sn in the Pb-Sn alloy changes the P-PbO_2/α-PbO_2 ratio and the structure of the PbO_2 layer. Sn content in Pb-Sn alloy is beneficial for the formation of β-PbO_2. LSV analysis shows that the novel Ti/PbO_2 electrodes have high oxygen evolution potential, which can reach 1.75 V.
