| 摘 要： | 热分解制备了RuTiSnMn／Ti阳极，在4mA／cm^2的电流密度下进行了恒电流试验。通过循环伏安法和交流阻抗谱研究了阳极在35g／LNaCl溶液、20g／LNaOH溶液和模拟孔隙液中的电化学行为．利用EsEM对阳极失效前后的微观形貌进行了观察,结果表明：阳极具有优良的耐析氯、氧反应能力；钛基体逐渐形成TiO2的钝化膜使阳极的氧化物膜电阻增大，活性组元的消耗使法拉第电荷传递电阻增加，这两者最终导致阳极失效。 |

| Abstract: | RuTiSnMn/Ti anode prepared by thermal decomposion was tested at a current density of 4mA/cm 2,characterized by cyclic voltammetry(CV)and electrochemical impedance spectroscopy(EIS) in 35g/L NaCl solution,20g/L NaOH solution and simulated porous water,in combination with surface morphology observation by scanning electron microscopy(SEM).Results showed that anode exhibited enough ability to tolerate the chlorine evolution and the oxygen evolution.The formation of an insulating layer of TiO 2 at the interface between the metallic base and the active coating resulting in the increase of oxide film resistance,the catalyst consumption induced the increase of charge transfer resistance of faradaic process evidently,which lead to the deactivity of the anode. |
| Keywords: | mixed metal oxides anode catalyst activity |
