The design and manufacture of advanced anode materials with superior quality are significant for assembling high-performance microbial fuel cells (MFCs). The present study aims to investigate the synergistic effect of MoS/CNTs nanocomposite as a novel anode-modifying material of MFCs. XRD, XPS, SEM, TEM and electrochemical analyses were performed to confirm the nanocomposite, to understand the morphology and to study the electrochemical properties of the modified electrodes. The performance of the MoS/CNTs/carbon paper (CP)-MFCs was investigated and compared with that of MoS/CP-MFCs, CNTs/CP-MFCs and CP-MFCs. The densest biofilm was formed on MoS/CNTs-modified anode compared to MoS/CP, CNTs/CP and CP anode, and MFCs with MoS/CNTs-modified anodes achieved the maximum power density of 645 ± 32 mW m, which is three times greater than MFCs with bare carbon paper anodes (213 ± 10 mW m). These results demonstrate that the synthesized MoS/CNTs nanocomposite could be exploited as an efficient anode catalyst for improving the performance of MFCs.
设计和制造具有优异质量的先进阳极材料对于组装高性能微生物燃料电池（MFC）至关重要。本研究旨在研究 MoS/CNTs 纳米复合材料作为 MFC 新型阳极修饰材料的协同效应。通过 XRD、XPS、SEM、TEM 和电化学分析来确认纳米复合材料，了解其形态并研究修饰电极的电化学性能。研究并比较了 MoS/CNTs/CP-MFCs、MoS/CP-MFCs、CNTs/CP-MFCs 和 CP-MFCs 的性能。与 MoS/CP、CNTs/CP 和 CP 阳极相比，MoS/CNTs 修饰阳极上形成了最密集的生物膜，而 MoS/CNTs 修饰阳极的 MFC 达到了 645±32 mW m 的最大功率密度，是 bare 碳纸阳极 MFC（213±10 mW m）的三倍。这些结果表明，合成的 MoS/CNTs 纳米复合材料可用作高效阳极催化剂，以提高 MFC 的性能。
