Abstract

Key findings

  • The system achieved high nitrogen removal efficiency (>90%) and bioelectricity recovery (up to 2.5 W/m²) from wastewater.
  • The use of MXene as an electrode material improved the system's performance and stability.
  • The shortcut nitrification-denitrification process was efficient in removing nitrogen from wastewater, reducing the need for external chemicals.
