摘要
为了获得电催化性能优良的阳极材料,采用电沉积法制备了不锈钢基聚乙二醇(PEG)改性PbO2电极,通过SEM比较了电极改性前后的形貌变化,通过析氧曲线、Tafel曲线和循环伏安曲线的测量考察了电极材料的催化活性、耐蚀性能。结果表明:经PEG改性的PbO2电极表面平整致密,有较好的电化学性能,有利于难降解苯酚溶液的电催化氧化降解。
In order to obtain anode material with good electrocatalytic activities, PbO2 electrode modified by polyethylene glycol （PEG） was prepared on stainless steel substrate by electrodeposition. The modified variations on surface morphology of the electrodes were examined by Scanning Electron Microscopy （SEM）. The properties of the electrodes, such as electrocatalytie activities, corrosion resistance were investigated by oxygen evolution curve, Tafel curve and cyclic voltammetry curves. The results show that modified PbO2 electrode is smooth and compact, and have good electrochemical properties, it will beneficial to degradation of phenol solution.
