摘要
采用热氧化法制备了IrO2-SnO2/Ti和IrO2-PdOx-SnO2/Ti两种电极.通过极化曲线、循环伏安曲线和寿命强化试验研究了它们在不同电阻率溶液(模拟淡海水和淡水)中的电化学行为,且进一步通过扫描电镜(SEM)对电极涂层寿命试验前后的表面形貌进行了分析研究.结果表明:钛基二氧化铱电极具有良好的电催化活性,在淡水环境中使用时,该阳极具有稳定性好、排流量大、重量轻、工作寿命长等优点.
IrO_ 2 SnO_2/Ti and IrO_2 PdO_x SnO_2/Ti electrodes were made by the thermal decomposition technique in air. The electrochemical behaviors of the anodes were studied by polarization curves,cyclic voltammetry curves and electrolytical experimentation in fresh water. Scanning electron microscopy provided information about the morphology of the coatings. The results showed that the precious metal oxide electrodes would show the advantages of stability,high current carrying capability,light weight and long service life when they are used in fresh water.So the titanium supported iridium dioxide anode will be the most gloriours auxiliary anode in the future.
