添加碳纳米管对钌铱锡氧化物阳极性能的影响
|
Abstract:
摘要 本文采用热分解法制备Ti/Ru-Ir-Sn氧化物阳极，运用TGA、SEM、EDS、循环伏安、电化学交流阻抗、极化曲线以及强化电解寿命测试方法，探讨添加不同含量碳纳米管（CNTs）对Ti/Ru-Ir-Sn氧化物阳极的影响规律. 热重分析和阳极能谱数据表明，在烧结温度470 oC条件下CNTs未发生高温氧化分解，仍以单质形式存在阳极涂层中. 与对比样品相比，涂层表面裂纹增多，但仍保持典型形貌. 添加CNTs显著改善了Ti/Ru-Ir-Sn氧化物阳极的电化学性能，增大了阳极的活性表面积，减小了涂层内部电阻，提高了阳极析氯电催化活性，析氯电位增加缓慢，阳极强化电解寿命也得到明显延长. 其中，添加0.1 g·L-1 CNTs的Ti/Ru-Ir-Sn氧化物阳极电催化活性和稳定性最优
