Microbial fuel cells (MFCs) convert cemical energy directly to electrical energy via electrochemically active microorganisms. The interaction between microbes and electrode surface is a key factor to increase power density of MFC. In this study, a novel polydopamine(PDA)/polypyrrole(PPY) modified carbon felt by a facile electrodeposition method for an improved MFC performance. The MFC equipped with PDA-PPY-CF anode presented 500 mW/m2, which was 1.5, 1.15, and 1.13 times greater than those of the unmodified carbon felt (CF), PDA-CF, PPY-CF, respectively. PDA has superior hydrophilicity and adhesive force for biofilm development, while PPY provides electrochemically active sites for electron transfer between biofilm and anode. These results show that modification with PDA/PPY provides excellent electrochemical properties for electrochemically active biofilm for MFC. |
