微生物燃料电池（MFC）是一种在处理废水过程中产生电能的新型能源技术，已成为环境保护和能源回收领域的新兴技术之一。在MFC的各个组成部分中，电极材料对MFC的发电起着至关重要的作用。在这项研究中，我们研究了碳纳米管（CNT）修饰的碳布电极在单室MFC中的性能。首先在废水中接种微生物，然后考察其以乙酸钠为燃料的性能。结果表明，碳布电极上包覆碳纳米管的MFC提高了功率密度。在本研究中，获得的最大功率密度为65 mW·m（-2），最高化学需氧量（COD）去除率为95%，最大库仑效率为67%。与其他报道的研究相比，碳纳米管/碳布复合电极已被证明是使用MFC的高潜力。(C)2009爱思唯尔有限公司版权所有。
Microbial fuel cell (MFC), which can produce electricity during treatment of wastewater, has become one of the emerging technologies in the field of environmental protection and energy recovery. Of all parts of MFC, the electrode materials play a crucial role in the electricity generation. In this study, we investigate the performance of carbon nanotube (CNT) modified carbon cloth electrodes in single-chamber MFC. The MFC is first inoculated with bacteria in wastewater and then its capability of using acetate sodium as fuel is examined. The results show that the MFC with CNT coated onto carbon cloth electrode improves the power density. In this study, the obtained maximum power density is 65 mW m(-2), the highest chemical oxygen demand (COD) removal efficiency is 95%, and the maximum Coulombic efficiency is 67%. Compared with other reported studies, the CNT/carbon cloth composite electrode has demonstrated high potential for the use of MFC. (C) 2009 Elsevier B.V. All rights reserved.
