Modified cobalt-manganese oxide-coated carbon felt anodes: an available method to improve the performance of microbial fuel cells.

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.
