摘要

Here we evaluated the graphite anodes activated by melamine, carbamide, ZnCl2 and H3PO4 inmicrobial fuel cells (MFCs). Results indicated that the graphite activated by melamine, carbamide andzinc chloride, respectively, could improve the voltage output and power densities, as well as decreasethe internal resistances. MFCs with graphite activated by melamine as anode achieved the highest3 maximum power generation (0.442W/m ), 26.8% greater than the untreated graphite. The reason forimproved performance is the introduction of nitrogen-containing functional groups on the electrodethat can increase the efficiency of electron transfer from the bacteria to the anode surface, enhancesurface wettability and improve bacterial adhesion. The chemical activation processes are the mostcost-effective because of simply immersion, no heating, no electrochemical process and no expensivechemicals.
