Microbial fuel cell (MFC) is the bio-electrochemical system which produces electricity using catalytic activity of microorganisms and also possesses an advantage of simultaneous waste-treatment. N-doped and three dimensional porous carbon structures have received considered attention as electrode material for MFC owing to its interconnected pore structure, large surface area, good electrical conductivity and relatively low cost. N-doped porous carbon foam possessing high surface area, 700 m2/g was synthesized using simple route, in which melamine foam was used as template and nitrogen source, whereas the strength of the foam was achieved with the formaldehyde-resorcinol polymer in appropriate ratio. We have also carried out the practical evaluation of the N-doped carbon foam as electrode materials for MFC using Shewanella oneidensis MR-1 (S. oneidensis). The MFC operated with N-doped carbon produced maximum power density of 31 W/m3 with 0.75 V OCV. The superior performance of the carbon foam electrode in the MFCs was attributed to the synergistic effects of the high surface area, good biocompatibility, and excellent electron transfer. |
