Effect of Current Density on Preparation and Properties of TF/β-PbO₂ in MSA Media.

ABSTRACT: The lead-based alloy and DSA anodes have drawbacks, such as poor corrosion resistance, easy peeling of coating, low electrocatalytic activity, and environmental pollution in electrode preparation processes. In this study, titanium foam/β-PbO₂ (TF/β-PbO₂) was prepared by electrodeposition in methanesulfonic acid (MSA) media. The current efficiency and the deposition rate were 89.7% and 5.36 v/(μm·min^-1) at the best current density of 80 mA·cm^-2, respectively. The TF/β-PbO₂ was characterized by electrochemical tests, X-ray diffraction (XRD), and scanning electron microscopy (SEM). The cyclic voltammetry (CV) test shows that the anodic peak potential of the optimum TF/β-PbO₂ was as low as 2.135 V and anodic voltammetry charge w
