摘要
研究了在Ti/Sb-SnO_2基体上制备Ti/Sb-SnO_2/β-PbO_2电极的过程中,镀液中掺杂Fe~(3+)对电极表面形貌、镀层物相组成、电催化活性和电极稳定性的影响,并分析了Fe~(3+)作为掺杂物的作用机理。通过扫描电镜(SEM)、X射线衍射(XRD)、阳极极化曲线、循环伏安曲线、交流阻抗谱、强化寿命测试和热震试验对电极性能进行了表征。结果表明,在镀液中掺杂Fe~(3+)能获得晶粒较大的PbO_2镀层,并能提升PbO_2镀层的电催化活性和稳定性,在表面镀层中仅含有β-PbO_2晶粒。当镀液中Fe~(3+)的掺杂量为0.015mol/L时,电极拥有最好的电化学和物理性能。
The Ti/Sb-SnO_2/β-PbO_2 electrode was prepared through electrochemical deposition on a Ti/Sb-SnO_2 substrate.The effects of Fe~(3+) concentration on surface morphology,phase composition,electrocatalytic activity and stability of the PbO_2 electrode were investigated by scanning electron microscopy(SEM),X-ray diffraction(XRD),anode polarization curves,cyclic voltammetry curves,electrochemical impedance spectroscopy,accelerated test life and thermal shock test.Results revealed that the average grain size of PbO_2 layer is becoming bigger with doped Fe~(3+) in electrodeposition solution and the electrocatalytic activity and the stability of PbO_2 electrode can be improved.The surface layer of Fe~(3+) doped the Ti/Sb-SnO_2/β-PbO2 electrode is mainly composed of β-PbO_2.The electrode obtained has the best electrochemical and mechanical properties when Fe~(3+) concentration is 0.015 mol/L in the bath.And the action mechanism of Fe~(3+) as the dopant is also analyzed.
