Abstract

Key findings

  • High-performance cathode catalysts were synthesized using metal-free materials, demonstrating improved power density and stability.
  • The catalysts showed excellent electrochemical properties, including high exchange current density and low charge transfer resistance.
  • The MFCs with the new catalysts exhibited improved performance, with a maximum power density of 1.2 W/m², a significant increase from the control group.
