摘　　要：通过电沉积法和热分解法将活性组分Ir、Sn、Ru、Mn分别负载到钛板上制成新型电极,探究活性层Ru、Mn组分浓度对新型电极电化学活性及抗腐蚀能力的影响。结果表明,当Ru、Mn摩尔比为50.0∶75.0时,电极具有较好的电化学活性和抗腐蚀能力,此时电极的析氯电位为1.092 V,析氧电位为1.185 V,自腐蚀电流密度为6.733×10^(-6)A/cm^(2)。The active component Ir,Sn,Ru,Mn was loaded on the titanium plate by electrodeposition method and thermal decomposition method to prepare a new type of electrode.The influence of the concentration of Ru,Mn component in the active layer on the electrochemical activity and corrosion resistance of new type of electrode was explored.When the molar ratio of Ru and Mn was 50.0∶75.0,the electrode had good electrochemical activity and corrosion resistance.At this time,the chlorine evolution potential of the electrode was 1.092 V,the oxygen evolution potential was 1.185 V,and the self-corrosion current density was 6.733×10^(-6)A/cm^(2).
