Novel Non-Metal Cathode Catalyst for Oxygen Reduction Reaction in Microbial Fuel Cells |
| 초록 |
The nitrogen and phosphorus-doped ordered mesoporous carbon (NPOMC) with highly active non-metal oxygen reduction catalyst was synthesized and showed comparable oxygen reduction reaction (ORR) activity to conventional cathode catalyst such as platinum. In this study, we reported performance of NPOMC in MFC and electrochemical properties with using LSV, CV and EIS as compared to platinum with platinum impregnated carbon black (Pt/C) catalysts in air-cathode MFC. In addition, we compared with effect of cathode electrode surface by microbe for NPOMC ORR mechanism between both MFCs. The synthesized NPOMC achieved a remarkable on-set potential compared to the previously reported metal-free catalysis in MFC. The open circuit potential and power density using NPOMC as compared to Pt/C, were 0.43 V and 0.58V, 245.77 mW/m2 and 329.78 mW/m2, respectively. The NPOMC showed a comparable voltage and maximum power density (75%) with considering the cost of just 10% of the platinum catalyst. |
