Bimetal-organic framework-derived porous CoFe2O4 nanoparticles as biocompatible anode electrocatalysts for improving the power generation of microbial fuel cells

MFCs equipped with CoFe₂O₄ anode achieved a maximum power density of 1026.68 mW m^-2, which was approximately 3.4 times higher than that of the pristine carbon cloth. Additionally, the biofilm density and viability on the anode were enhanced after CoFe₂O₄ modification. Considering the facile fabrication process and superior electrocatalytic performance, the CoFe₂O₄ nanoparticles are promising electrocatalysts for high performance and cost-effective MFCs.
