제목 Microwave and acid-treated Expandable Graphite Granule for Enhancing the Bioelectricity Generation of Microbial Fuel Cells
초록 Microbialfuel cells (MFCs) convert organic acid (e.g. Acetate) as a carbon source tobioelectricity using electroactive bacteria. The interactions betweenelectroactive bacteria and the electrode surface of a carbonaceous electrodeplay a key role in capturing the respiratory electrons from electroactivebacteria. In this study, a microwave and sulfuric acid treatment was used to modify thesurface structure of graphite granules. The prepared expandable graphite granules(EGG) exhibited a 1.5 times higher power density than the unmodified graphitegranules (1400 vs. 900 mW/m3). SEM and FT-IR revealed improved physicochemical properties of the EGG surface. These resultssuggest that physical and chemical surface modification using sulfuric acid andmicrowave heating improves the performance of electrode-based bioprocesses,such as microbial electrosynthesis (MES) and microbial electrolysis cell (MEC),not only MFCs.
