摘要:
以碳纸为支撑体,氯铱酸为前体,利用二氧化钛纳米棒阵列作为载体,采用浸渍-热分解法成功制备了 IrO2-TiO2/C 一体化析氧电极。通过扫描电镜(SEM)、XRD、XPS和电化学方法---循环伏安(CV)、交流阻抗(EIS)等手段,研究了载体形貌对析氧电极性能的影响。结果表明:二氧化钛载体能有效抑制支撑体碳纸在高电位下的腐蚀,当电压为2.4 V时,极化电流才仅为13.2 mA/cm2,一体化析氧电极积分电荷由 87.2 mC/cm2增至 178.5 mC/cm2 ,电极电化学反应阻抗由 3.13 Ω·cm2 降低到 1.62Ω·cm2,极大地提高了析氧电极的接触面积和催化剂的电催化活性。
