摘要: Lead dioxide electrodes were prepared by pulse electrodeposition in the lead nitrate solution with different current density. The effects of density on morphology and structure studied scanning electron microscopy (SEM) X-ray diffraction (XRD), respectively. SEM XRD results show that increase can make more fine, crystal size decreases anodic polarization curves demonstrate oxygen evolution overpotentials also enhance stability enhances until 15 mA cm–2, then decreases. electrocatalytic property was examined for electrochemical oxidation rhodamine B (RhB). RhB removal efficiency increases density, which be attributed to overpotential.
