摘要

纳米材料修饰阳极可显著提高微生物燃料电池（MFC）性能，本研究主要探索了石墨烯、聚苯胺和石墨烯/聚苯胺复合修饰电极对MFC产电性能的影响。使用电化学方法电镀石墨烯于碳布表面，进一步通过原位聚合法制备聚苯胺来修饰碳布电极。将修饰电极装载入双室型MFC中，测量其产电性能，并对电极进行表征，测量电化学性能。通过扫描电镜观察到

碳布能够被修饰上石墨烯和聚苯胺，并且聚苯胺附着于碳纤维或石墨烯薄层表面，形成棒状的纳米结构。产电性能方面，装载石墨烯/聚苯胺修饰电极的MFC最大输出电压最高，达到了（291±22）mV，比装载空白碳布电极的对照组MFC提高了175%以上。石墨烯/聚苯胺电极组MFC的最大输出功率密度同样最高，达到了（653 ± 25）mW·m

-2

，为空白碳布对照组的10.5倍。实验结果表明：石墨烯/聚苯胺复合修饰电极可有效利用石墨烯导电性好和聚苯胺生物相容性高的优点，显著提高MFC的产电性能。

Abstract

Nanomaterial modified anode can significantly improve the performance of microbial fuel cell (MFC). The effects of graphene

polyaniline and graphene/polyaniline composite modified electrode on the power output of MFC is mainly explored in this paper. Graphene was electroplated on the surface of the carbon cloth by electrochemical method

and the polyaniline was further prepared by

situ

polymerization to modify the carbon cloth electrode. The modified electrodes were further loaded into a dual-chamber MFC

and the power generation performance was measured. It was observed by scanning electron microscopy that graphene and polyaniline could be modified on the ca

rbon cloth

and polyaniline adhered to the surface of the carbon fiber or graphene thin layer to form a rod-shaped nanostructure. In terms of electricity production performance

the maximum output voltage of MFC loaded with graphene/polyaniline composite modified electrode reached (291±22) mV

which was more than 175% higher than that of the control group loaded with unmodified carbon cloth electrode. The maximum power density of the graphene/polyaniline composite modified electrode group reached (653 ± 25) mW·cm

-2

which was 10.5 times of the control group. The results show that the graphene/polyaniline composite modified electrode can effectively utilize the advantages of good conductivity of graphene and high biocompatibility of polyaniline

and significantly improve the power output of MFC.
