采用溶胶凝胶法制备Ru-Ir-Sn-Ti阳极涂层,对涂层进行析氯电位、析氧电位、极化曲线、循环伏安曲线、电化学交流阻抗等电化学测试以及强化电解寿命测试,并与热分解法制备的阳极涂层进行对比。结果表明:与热分解法制备的阳极涂层相比,溶胶凝胶法制备的Ru-Ir-Sn-Ti阳极涂层具有较低的析氯电位、较高的析氧电位、良好的电催化活性和较长的强化电解寿命。

Ru-Ir-Sn-Ti oxideanode coating were prepared by sol-gel method, and the electrochemical property and durability of the anode coating were investigated by oxygen evolution potential, chlorine evolution potential, cyclic voltammetry curve, polarization curve, electrochemical impedance and accelerated lifetime and compared with oxide anode coating prepared by thermal decomposition method. The results show that anode coating prepared by sol-gel method have lower chlorine evolution potential, higher oxygen evolution potential, longer accelerated lifetime and better electro-catalytic activity than metal oxide anodes coating prepared by thermal decomposition method.
