Abstract

Key findings

  • Graphene/biofilm composites showed improved oxygen reduction reaction rates compared to control samples.
  • The composites were formed through a simple and scalable in situ method, allowing for efficient integration into biocathode microbial fuel cells.
  • The enhanced performance of the composites was attributed to the synergistic effects between graphene and biofilm, leading to increased electron transfer and catalytic activity.
