通过向溶胶凝胶制备体系中加入有机添加剂四乙基氢氧化铵(TEAOH)、四丙基溴化铵(TPABr)和十六烷基三甲基溴化铵(CTAB)制备了Ru0.5Ir0.5O2钛基涂层阳极。采用扫描电镜(SEM)、循环伏安法、极化曲线和强化寿命测试研究了电极的微观结构、电化学性能和稳定性。结果发现,加入TEAOH可显著增大涂层的真实表面积和减小电极的极化程度,从而大大提高电极的电催化活性,同时保持了电极的高稳定性。
Ru0.5Ir0 was prepared by adding tetraethylammonium hydroxide (TEAOH), tetrapropylammonium bromide (TPABr) and cetyltrimethylammonium bromide (CTAB) to the sol-gel preparation system. 5O2 titanium-based coating anode. The microstructure, electrochemical properties and stability of the electrode were investigated by scanning electron microscopy (SEM), cyclic voltammetry, polarization curves and enhanced life test. The results showed that the addition of TEAOH can significantly increase the surface area of the coating and reduce the degree of polarization of the electrode, thereby greatly improving the electrocatalytic activity of the electrode, while maintaining the high stability of the electrode.
