| 中文摘要: |
| 采用二次阳极氧化法在纯净的钛片表面制备出TiO2纳米管，经表面清洗后将其放入带
聚四氟乙烯衬里的反应釜中，同时向釜中加入一定量的 Keggin 型铁取代杂多酸盐 Cs4PW11O39Fe
（III）（H2O）（CsPW11Fe）水溶液，通过水热法在 TiO2 纳米管内生长 CsPW11Fe 晶体，最终得到
CsPW11Fe/TiO2纳米管修饰电极。通过SEM和XRD对该修饰电极进行了表征，研究了其电化学性
能以及对H2O2的电催化行为。结果表明，CsPW11Fe/TiO2纳米管修饰电极的峰电流与峰电位随H2O2
浓度不同而发生明显的变化，因此可以作为电化学传感器应用于H2O2的检测。 |
| 英文摘要: |
| TiO2 nanotubes were prepared through a two-step anodic oxidation on the surface of pure titanium thin slice.
Then, it and Keggin-type iron-substituted heteropolyacids salt Cs4PW11O39Fe(III)(H2O) (CsPW11Fe) solution was put into re⁃
action cauldron with Teflon lining. CsPW11Fe crystal grew up inside TiO2 nanotubes and CsPW11Fe/TiO2 nanotubes modi⁃
fied electrode was obtained through the hydrothermal method. The modified electrode was characterized by XRD and SEM.
The electrochemical performances of the modified electrode and its electrocatalytic behavior of H2O2 were also investigated.
The results show that the peak current and peak potential of CsPW11Fe/TiO2 nanotubes modified electrode have obvious
changes with different concentrations of H2O2. Therefore, it is possible to be used as an electrochemical sensor for H2O2 de⁃
tection. |
