Therefore, the objective of this study was to investigate the feasibility
of using spinel Mn–Co oxide as cathode catalyst in MFCs to
enhance power generation and substrate degradation. The prepared
Mn–Co oxide with different initial atomic ratio of Mn and
Co were examined in terms of electrochemical and biochemical
reactions in MFCs. Moreover, the performance of Mn–Co oxide catalysts
was compared with that of platinum to explore the possibility
of using Mn–Co oxide to replace platinum as cost-effective
cathode catalyst in MFC applications.
