将组元Zr和Y引入钛阳极氧化物涂层制备体系,采用热分解法在TA2基材上制备出Ru0.4Zr0.6O2、Ru0.32Zr0.48Y0.2O1.9涂层电极。采用XRD分析电极涂层的组织结构,测试各电极的析氯析氧电位、极化曲线、循环伏安曲线以及电极的稳定性,同时与同条件下制备的RuO2进行对比分析。研究结果表明,经450℃烧结制备的Ru0.32Zr0.48Y0.2O1.9三元电极涂层的综合性能比RuO2优越。说明添加Zr和Y组元,能有效提高涂层的析氯电催化活性和强化寿命。
The components Zr and Y were introduced into the titanium anodic oxide coating preparation system, and Ru0.4Zr0.6O2 and Ru0.32Zr0.48Y0.2O1.9 coated electrodes were prepared on the TA2 substrate by thermal decomposition method. The structure of the electrode coating was analyzed by XRD. The potential of chlorine evolution, the polarization curves, the cyclic voltammetry curves and the stability of the electrodes were tested. Meanwhile, RuO2 was also compared with that of RuO2 prepared under the same conditions. The results show that the Ru0.32Zr0.48Y0.2O1.9 ternary electrode coating prepared by sintering at 450 ℃ has better comprehensive performance than RuO2. It shows that the addition of Zr and Y components can effectively improve the catalytic activity of chlorine evolution and strengthen the life of the coating.
