| 摘 要： | 考察了氧化石墨烯（GO）修饰活性炭（AC）空气阴极（AC-GO阴极）对微生物燃料电池（MFC）产电性能以及有机物去除率的影响。实验结果表明，向AC阴极中掺杂一定量的GO可以降低阴极的内阻，提高阴极电化学反应速率。其中，GO掺杂量为0.5 mg·cm-2的AC-GO0.05阴极性能最好，该AC-GO0.05阴极MFC体系的最大功率密度（Pmax）为767 mW·m-2，是空白AC阴极体系Pmax（459 mW·m-2）的1.7倍，化学需氧量（COD）去除率和库伦效率（CE）均明显高于空白AC阴极体系。

| Abstract: | The effect of a graphene oxide (GO)-modified activated carbon (AC) cathode (AC-GO) on the performance and organics removal efficiency of a microbial fuel cell (MFC) was investigated. Based on the results, doping moderate amounts of GO into an AC air-cathode reduced the internal resistance of the cathode and accelerated the cathodic reaction rate. The AC-GO0.05 cathode outperformed the other AC-GO cathodes and the blank AC cathode. The maximum output power density (Pmax) of the MFC with the AC-GO0.05 cathode was 767 mW·m-2, which is 1.7 times higher than that of the MFC with the blank AC cathode. Meanwhile, both the COD removal efficiency and the coulomb efficiency (CE) of the MFC with the AC-GO0.05 cathode were higher than those of the MFC with the blank AC cathode. |
