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。
