Synergistic elimination of antibiotic resistance genes and tetracycline antibiotics in wastewater via a Z-scheme Bi 2 WO 6 /g-C 3 N 4 heterojunction: degradation pathways and mechanism

YLYuankun LiuGSGangyi SunYCYang Cao

Key Points

  • The study aims to explore the degradation of tetracycline antibiotics and antibiotic resistance genes using a Bi2WO6/g-C3N4 heterojunction.
  • Utilization of a Z-scheme Bi2WO6/g-C3N4 composite
  • Identification of key reactive species in degradation processes
  • Examination of charge separation mechanisms
  • h+ and ˙O2− were identified as the main reactive species for degradation.
  • The heterojunction demonstrated enhanced charge separation.
  • Effective elimination of tetracycline antibiotics and antibiotic resistance genes was achieved.

Abstract

h + and ˙O 2 − as the dominant reactive species responsible for the degradation of TCs and ARGs and A Z-scheme heterojunction mechanism was proposed for the Bi 2 WO 6 /g-C 3 N 4 composite to explain the enhanced charge separation.
