摘要：

Microbial fuel cells (MFCs) can generate energy while processing organic pollutants, which has a great impact on environmental wastewater treatment applications. In this study, a gel polymer was formed by Co-Fe-N co-doping biochar (Co-Fe-N@BC), which was used as the anode material to improve the electricity generation performance of MFC. The Co-Fe-N@BC material prepared at 900(degrees)C carbonised biomass into more graphitic carbon, and its total resistance (3.56 Omega) was significantly reduced. In the corresponding dual-chamber MFC, the current density was 2.81 A/m(2), and the power density reached 1181 mW/m(2) at maximum. Among the materials tested, the Co-Fe-N@BC anode MFC had the highest chemical oxygen demand removal rate and coulombic efficiency, reaching 91% and 13%, respectively. It is proved that MFC with Co-Fe-N@BC anode has the best electrochemical performance. [GRAPHICS]
