Abstract

Key findings

  • The sulfur-doped MXene/polypyrrole hydrogel anode showed improved conductivity and surface area compared to traditional anodes.
  • The anode facilitated enhanced extracellular electron transfer, leading to increased power output in microbial fuel cells.
  • The power output of the microbial fuel cell was boosted by up to 25% using the sulfur-doped MXene/polypyrrole hydrogel anode.
