Microbial fuel cells (MFCs) is one of the pioneering studying field of environmental energy because of its unique advantages which can do wastewater treatment and electricity generation at once. However, to commercialize MFCs, overcoming low performance of MFCs by slow oxygen reduction reaction (ORR) is primarily goal. To solve this problem, we couple conventional bioanode with a TiO2 photoanode to build hybrid MFC. By attaching photocatalytic photoanode, it supplies photogenerated electrons to MFC's circuit, which accelerate ORR, and it makes enhanced power density performance (1284±20 mW m-2) comparing normal one (850±12 mW m-2). Moreover, we can prove TiO2 photoanode of hybrid MFC have ability to reduce CO2 to methane (1.10 ppm cm-2 h-1). |
