摘要：
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 in-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 carbon 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. © All Right Reserved.
