Abstract


In this study, we synthesize low-cost Fe3O4 catalyst and spray it on carbon cloth as the cathode material while carbon cloth with low functionalization of graphene oxide (GO) as the anode material. The dairy wastewater and diesel wastewater are used as the anolyte and catholyte, respectively for microbial fuel cells (MFCs), which combine with the bio-electro-Fenton system to degrade organic wastewater. It improves the Chemical Oxygen Demand (COD) degradation efficiency of 85% of organic pollution. Moreover, the application of non-photocatalyst-Fe3O4 helps to improve the performance of electricity generation and achieves the goals of replacing the existing microbial fuel cells catalyst in the future.
