    摘要:

    采用粉末冶金法制備了不同Co含量（0.5%，1.0%，2.0%，質(zhì)量分?jǐn)?shù)）的Pb-Co陽極，并與傳統(tǒng)的Pb-Ca-Sn陽極進(jìn)行了對比試驗。通過電化學(xué)測試研究了陽極在160 g/L H2SO4、500 mg/L Cl-電解液中的電化學(xué)行為，研究了恒電流極化72 h后陽極氧化層的物相組成、表面形貌和元素分布。隨著Co含量的增加，Pb-Co陽極的電位、電荷傳遞電阻和析氧過電位逐漸降低。恒電流極化72 h后，Pb-2%Co陽極的析氧過電位比Pb-Ca-Sn陽極低101 mV。此外，在Cl-的存在下，電荷傳遞得到改善，析氧反應(yīng)受到抑制，陽極氧化層惡化。

    Abstract:

    Pb-Co anodes with different Co contents (0.5wt%, 1wt%, and 2wt%) were prepared by powder metallurgy, and the traditional Pb-Ca-Sn anode was used as the reference for comparison. The electrochemical behavior of the anodes in the electrolyte containing 160 g/L H2SO4 and 500 mg/L Cl- ions was evaluated by electrochemical measurements. The phase composition, surface morphologies, and element distribution of the anodic oxide layers after galvanostatic polarization for 72 h were investigated. With increasing the Co content, the anodic potential, charge transfer resistance, and oxygen evolution overpotential of the Pb-Co anodes are decreased gradually. After galvanostatic polarization for 72 h, the oxygen evolution overpotential of Pb-2wt% Co anode is lower than that of Pb-Ca-Sn anode by 101 mV. In addition, due to the presence of Cl- ions, the charge transfer is improved, the oxygen evolution reaction is inhibited, and the oxide layer is deteriorated.
