A photo-driven bioanode was constructed using the thylakoid membrane from spinach, carbon nanotubes, and an artificial mediator. By considering a linear free-energy relationship in the electron transfer from the thylakoid membrane to the mediators, and the oxygen resistance of the reduced mediators, 1,2-naphthoquinone was selected as the most suitable mediator for the photo-driven bioanode. Water-dispersed multi-walled carbon nanotubes served as scaffolds to hold the thylakoid membrane on a porous electrode. The constructed photo-driven bioanode exhibited a photocurrent density of over 100 μA cm−2 at a photon flux density of 1500 μmol m−2 s−1.

使用类囊体膜和多壁碳纳米管构建光驱动生物阳极

使用来自菠菜的类囊体膜,碳纳米管和人工介体构建了光驱动生物阳极。考虑到电子从类囊体膜到介体的转移中的线性自由能关系,以及还原介体的抗氧性,选择了1,2-萘醌作为光驱动生物阳极的最合适介体。水分散的多壁碳纳米管用作支架,将类囊体膜固定在多孔电极上。所构建的光驱动生物阳极在1500μmolm -2  s -1的光子通量密度下表现出超过100μAcm -2的光电流密度。
