Abstract

Abstract:

The anodic galvanostatic electrodeposition technique has been used for preparing PbO2 and Fe-doped PbO2 electrodes on stainless steel substrate.The crystal phase structure,surface morphology and element composition of the electrodes are characterized and analyzed by X-ray diffraction,scanning electron microscopy and energy dispersive spectroscopy.The degradation rate of phenols simulated wastewater by electro-catalytic oxidation method with the PbO2 electrode and Fe-doped PbO2 electrode on stainless steel substrate is studied.The results show that the surface morphology and diffraction intensity of Fe-doped PbO2 electrode have changes in different degrees.The added Fe3+ ions may enter into PbO2 surface layer,and the Fe-doped PbO2 electrode has better electro-catalytic oxidation capacity than common PbO2.

Key words: electrodeposition, Fe-doped PbO2 electrode, electro-catalysis

摘要：

采用阳极恒电流电沉积技术制备不锈钢基PbO₂电极及掺杂Fe-PbO₂电极。采用XRD、SEM、EDS等方法对电极的物相结构、表面形貌、元素组成进行了表征和分析,对PbO₂电极及掺杂Fe-PbO₂电极电催化氧化酚类模拟废水的降解率进行研究,结果表明:掺杂Fe-PbO₂电极表面形貌及衍射强度发生不同程度的改变,添加的Fe3+可能进入了表层内部,掺杂Fe-PbO₂电极较普通的PbO₂电极对酚类废水具有更好的电催化氧化降解性能。
