Ti/Sn_((1-x))Ir_xO_2电极制备及电生活性氯特性

Preparation of Ti/Sn_((1-x))Ir_xO_2 Electrode and Its Property of Electrogenerating Active Chlorine

通过热分解法制备了Ti/Sn(1-x)IrxO2电极,应用SEM观察了电极的表面形貌,通过线性伏安法、循环伏安法等实验方法测试了电极的电化学性能。实验结果表明,Ti/Sn0.7Ir0.3O2电极具有较好的析氯活性;电解产生的活性氯浓度随电流密度的增加先增加后降低;升高电解温度不利于活性氯的产生。

Ti/Sn（1-x）IrxO2 electrodes were prepared on titanium substrates by thermal decomposition method.The surface morphologies of electrodes were characterized by scanning electron microscopy（SEM）,and the electrochemistry of electrodes were tested by linear scan voltammetry,cyclic voltammetry etc..The Ti/Sn0.7Ir0.3O2 electrodes had best electrocatalytic activity of generating active chlorine,and electrolytic active chlorine concentration increased in the beginning and then decreased along with increase of current density,while increasing of electrolyte temperature was not use of producing active chorine.
