采用双脉冲电沉积,在Pb-0.3%Ag(质量分数,下同)合金基体表面制备了Pb-0.3%Ag/Pb-CeO2复合阳极材料,研究了不同正向脉冲平均电流密度(2~5 A·dm-2)和镀液中CeO2颗粒浓度(0~20 g/L)下制备的复合阳极材料电化性能,在50 g·L-1 Zn2+,150 g·L-1 H2SO4,35℃溶液中测试了阳极极化曲线、循环伏安曲线和塔菲尔曲线,获得了析氧动力学参数、伏安电荷、腐蚀电位和腐蚀电流。结果表明:在正向脉冲平均电流密度为3 A/dm2和镀液中CeO2颗粒浓度为15 g/L下制备的Pb-0.3%Ag/Pb-CeO2复合阳极材料在[ZnSO4+H2SO4]溶液中具有较高的电催化活性,较低的析氧过电位,较好的电极反应可逆性和耐腐蚀性。在[ZnSO4+H2SO4]溶液中,复合阳极材料在测试电流密度500 A/m2下的析氧过电位为1.134V,比Pb-1%Ag合金降低37 mV;腐蚀电流为1.97×10-4 A,明显低于Pb-1%Ag合金,表现出了良好的耐腐蚀性能。 The Pb-0.3% Ag / Pb-CeO2 composite anode material was prepared on the surface of Pb-0.3% Ag (mass fraction) alloy by double pulse electrodeposition. The effects of different forward pulse average current densities A · dm-2) and the concentration of CeO2 particles in the bath (0 ~ 20 g / L) were studied. The electrochemical performance of the composite anode materials was investigated under the conditions of 50 g · L-1 Zn2 +, 150 g · L-1 H2SO4, 35 ℃ The anodic polarization curves, cyclic voltammetry curves and Tafel curves were tested and the oxygen evolution kinetic parameters, voltammetric charges, corrosion potentials and corrosion currents were obtained. The results show that Pb-0.3% Ag / Pb-CeO2 composite anode material prepared in the [ZnSO4 + H2SO4] solution at an average forward current density of 3 A / dm2 and a CeO2 particle concentration of 15 g / It has higher electrocatalytic activity, lower oxygen overpotential, better electrode reversibility and corrosion resistance. In [ZnSO4 + H2SO4] solution, the anodic overpotential of the composite anode material at the test current density of 500 A / m2 was 1.134V, which was 37 mV lower than that of the Pb-1% Ag alloy. The corrosion current was 1.97 × 10-4 A , Which is obviously lower than that of Pb-1% Ag alloy, showing good corrosion resistance.
