The novel MnCoO (MCO/CF), CNTs-MnCoO (CNTs-MCO/CF) and MnFeO-MnCoO (MFO-MCO/CF) electrodes were prepared on carbon felt (CF) by simple hydrothermal and coating method as anodes for MFC. The modified anodes combine the electrocatalytic properties of transition metal oxides (TMOs), the high electrical conductivity of CNTs and the good biocompatibility of CF. These anodes play a synergistically role in the synthesis of structural, to realize high-efficiency electron transfer, low resistance and sufficient space for microbial colonization, while also ensuring high power density. The maximum power density of the composite electrodes CNTs-MCO/CF and MFO-MCO/CF were 4268 mW/m and 3660 mW/m, respectively. The synergistic effect of multi-component effectively improves the performance of MFC. This work not only offers a good design and preparation concept for functional TMOs composite electrodes, but also provides an important guide for the fabrication of CNTs-doped MFC anodes.
新型 MnCoO（MCO/CF）、CNTs-MnCoO（CNTs-MCO/CF）和 MnFeO-MnCoO（MFO-MCO/CF）电极通过简单的水热和涂覆方法在碳毡（CF）上制备，作为 MFC 的阳极。改性阳极结合了过渡金属氧化物（TMOs）的电催化性能、CNTs 的高导电性和 CF 的良好生物相容性。这些阳极在结构合成中发挥协同作用，实现高效电子转移、低电阻和微生物定植的充足空间，同时确保高功率密度。复合电极 CNTs-MCO/CF 和 MFO-MCO/CF 的最大功率密度分别为 4268 mW/m 和 3660 mW/m。多组分的协同效应有效提高了 MFC 的性能。这项工作不仅为功能性 TMOs 复合电极的设计和制备提供了一个很好的概念，也为 CNTs 掺杂 MFC 阳极的制备提供了重要的指导。
