  • 摘要: 本文通过真空过滤含有石墨烯的产电菌悬液直接在不锈钢网(SSM)表面形成石墨烯掺杂生物阳极,并运行单室微生物燃料电池(Microbial Fuel Cell,MFC)考察其对体系运行性能的影响.实验结果表明,向生物膜中掺杂石墨烯可有效缩短MFC的启动时间,降低阳极的内阻,提高阳极生物膜内的电子传递效率.与纯生物膜阳极体系相比,随着掺杂量的增加,石墨烯掺杂生物阳极MFC体系的阳极电荷转移电阻(Rct)依次降低,由29.3 Ω降低到18.1 Ω,体系的库伦效率(CE)由50.03%增大到73.97%,体系的最大功率密度(Pmax)由纯生物膜阳极体系的118 mW·m-2增大到588 mW·m-2.
    Abstract: In this study, the graphene doped bioanodes were prepared by simply vacuum filtrating bacterial suspension contained graphene onto stainless steel meshes (SSM). The performance of the as-synthesized bio-anodes was tested in single chamber microbial fuel cells (MFCs). Based on the results, doping moderate amount of graphene into the anodic biofilm was able to shorten the start-up time of MFC, reduce the internal resistance of the anode and increase the electron transfer efficiency in the anode biofilm. With the increase of the graphene doping amount, the charge transfer resistance (Rct) of the bio-anodes gradually decreased from 29.3 Ω to 18.1 Ω, and the coulombic efficiency (CE) and the maximum output power density (Pmax) of the corresponding MFCs increased from 50.03% and 118 mW·m-2 to 73.97% and 588 mW·m-2, respectively.
