Abstract
The electrochemical interaction between bacteria and electrode should be further strengthened at the present stage in order to develop microbial fuel cells (MFCs) to practical power sources. Developing effective anode materials is an alternative to achieving this goal. In this study, the redox activity of polyaniline (PAn) in neutral pH solution was improved by doping ionic liquid (IL) into the synthesized PAn; and the current output of MFC could be enhanced by using IL doped polyaniline (PAnIL) film as anode material. Both cyclic voltermmeter (CV) measurement and MFC operation showed that PAnIL electrochemically synthesized in solution with 30%(v/v) IL addition exhibited the best performance.
Key findings
- Doping ionic liquid into polyaniline improved its redox activity in neutral pH solution.
- IL-doped polyaniline film as anode material enhanced the current output of microbial fuel cells.
- 30% (v/v) IL addition in solution resulted in the best performance of IL-doped polyaniline.
