我们报道了薄，透明，高催化碳纳米管薄膜的合成。纳米管催化三碘化物的还原，这是一个对染料敏化太阳能电池很重要的反应，通过电化学阻抗谱测量的电荷转移电阻随着膜厚度的增加而减小。此外，将纳米管暴露在臭氧中可以显著提高催化活性，从而引入缺陷。臭氧处理的有缺陷的纳米管薄膜可以作为染料敏化太阳能电池的催化、透明和导电电极。其他可能的应用包括电池、燃料电池和电分析设备。
We report on the synthesis of thin, transparent, and highly catalytic carbon nanotube films. Nanotubes catalyze the reduction of triiodide, a reaction that is important for the dye-sensitized solar cell, with a charge-transfer resistance as measured by electrochemical impedance spectroscopy that decreases with increasing film thickness. Moreover, the catalytic activity can be significantly enhanced by exposing the nanotubes to ozone in order to introduce defects. Ozone-treated, defective nanotube films could serve as catalytic, transparent, and conducting electrodes for the dye-sensitized solar cell. Other possible applications include batteries, fuel cells, and electroanalytical devices.
