| 摘 要： | 采用溶胶-凝胶法制备了碳纳米管/纳米TiO2(CNT/nano-TiO2)复合溶胶,通过提拉法将复合溶胶涂覆在Ti基体上制得CNT/nano-TiO2复合膜修饰电极(C电极),其电化学性能经循环伏安、计时库仑、交流阻抗谱(EIS)等方法研究.研究结果表明,CNT可阻碍nano-TiO2粒子团聚.在循环伏安图中,C电极的氧化还原峰电流比nano-TiO2膜修饰电极(P 电极)的高出两倍多.通过对草酸溶液的异相电催化反应进一步证明C电极比P电极具有更高的电催化活性,而且对双氧水也有很强的异相电催化还原能力. |
| 关 键 词： | 碳纳米管 nano-TiO2膜 修饰电极 异相电催化性能 |

| Abstract: | Complex sol of CNT/nano-TiO2 was prepared by sol-gel method.The sol was coated on Ti matris to obtain a novel complex CNT/nano-TiO2 modified electrode(C electrode).The electrochemical properties of C electrode were investigated by cyclic voltammetry,chronocoulometry and EIS.The results showed that CNT can block congregation of nano-TiO2 particle,the current values of the second redox peaks of C electrode were about twice higher than that of pure nano-TiO2 modified electrode(P electrode) in cyclic voltammogr... |
