Abstract PbO2electrodes modified with different concentrations of polyvinylpyrrolidone (PVP) were prepared using electrodeposition method. The microstructure and electrochemical properties of the modified electrode were investigated using SEM, XRD, electrochemical impedance spectroscopy (EIS) and liner sweep voltammetry (VA) techniques. Results show that PVP molecules can be coated around PbO2 particles and can restrict their further growth and polymerization, which lead to a uniform and fine crystalline grains. The modified electrode presents a relatively lower charge transfer resistance as well as a higher oxygen evolution potential. Appropriate amount of PVP can enhance the electrocatalytic activity of electrode and the optimum doped concentration is 0.4 g·L−1. The modified electrode also exhibit excellent corrosion resistance and electrocatalytic stability. After having been used for 90 h, the degradation ratio of phenol can still reach 81.5%.
