The dimensional stable lead electrodes modified by sodium dodecyl sulfate (SDS) were prepared with electrochemical deposition and it shows that a more compact, uniform, and smooth film of Ti/PbO 2 (F+SDS) electrode reduces the corroded crystal faces and surface defects. Characterization results demonstrate that the oxygen evolution potential (OEP) of the Ti/PbO 2 (F+SDS) electrode was higher, and its service life is almost 1.6 times longer than the Ti/PbO 2 (F) electrode. Compared with Ti/PbO 2 (F) electrode, the soluble Pb concentration of the Ti/PbO 2 (F+SDS) electrode decreased 15.1%, which indicates that the decrease of crystal surface defects leads to the reduction of Pb ions so that the excellent corrosion resistance electrodes cause low environmental risks. The modified electrodes were used as anodes to degrading bisphenol A (BPA) when an electrolyte is 0.2 M Na 2 SO 4 , the applied voltage is 5 V and electrodes distance is 3 cm, 20 mg/L BPA for electrolysis time of 180 min can reach up to 97.6%.

Electrochemical oxidation has been considered as an efficient method to degrade pharmaceuticals and personal care products. Maintaining low power consumption while increasing the number of oxidation intermediates is deserving of exploring. Herein, Ti/SnO2–Sb/Zr0.3Ir0.7O2 was prepared by Zr doped into IrO2 and used for Sulfamethoxazole (SMX) degradation. The addition of Zr significantly increased the electrochemically active area and facilitated the catalyst to degrade SMX dramatically at a lower overpotential. The extremely outstanding lifetime of catalysts can reach 800 h during the accelerated life test, which showed excellent stability and developmental prospects. The overpotential at 10 mA·cm–2 is about 329 mV, indicating that this electrode has a high oxygen evolution reaction activity. Furthermore, the electrical efficiency per log order for the electrode is only 8.50 kW h m–3 at 4 V. Our research provides new anode electrochemical catalysts for the degradation of organic pollutants.
