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 100μAcm at a photon flux density of 1500μmolms.
采用菠菜类囊体膜、碳纳米管和人工介体构建了光驱动生物阳极。通过考虑从类囊体膜到介体的电子转移中的线性自由能关系以及还原介体的耐氧性，选择 1,2-萘醌作为光驱动生物阳极的最适介体。水分散多壁碳纳米管用作支架，将类囊体膜固定在多孔电极上。构建的光驱动生物阳极在 1500μmolms 的光通量密度下表现出超过 100μAcm 的光电流密度。
