Abstract

PbO2 electrodes modified with different concentrations of polyethylene glycol (PEG) were prepared by electrodeposition. SEM and XRD were employed to investigate the surface morphology and crystal structure of PbO2 electrodes, and its electrocatalytic acitivity was analyzed through degradation experiments of phenol. Furthermore, electrochemical impedance spectroscope (EIS) and liner sweep voltammetry (VA) were carried out to get a better understanding of its electrochemical properties. SEM images and XRD patterns show that PEG can decrease the partical size of PbO2 and improve the crystal purity of β-PbO2. The modified electrodes exhibite better electrocatalytic activity, lower charge transfer resistance and higher oxygen evolution potential compared with unmodified electrodes in the electrochemical experiments. Additionally, five times degradation experiments of phenol and accelerated lifetime tests reveal that the optimal electrode modified with 6g/L PEG has excellent electrocatalytic stability, longer lifetime and better corrosion resistance.

Key words： polyethylene glycol (PEG); lead dioxide; modified electrode; electrocatalytic
