摘要：Electron transfer process (ETP) is considered an important mechanism for degrading pollutants in Fenton-like reactions. In this study, we introduce a novel and efficient non-contact ETP (NCETP) in layered double hydroxides/peroxymonosulfate (LDH/PMS) system for antibiotic degradation. This process avoids the side reactions associated with traditional ETP, maintaining the high selectivity (98.4 %). When applying it to a continuous-flow reactor, LVX removal efficiency can remained at 99 % within 24 h of continuous operation. It has been confirmed that pollutants and PMS are separated on two sides of the catalyst, these two compounds cannot have direct contact. The single-coordinated oxygen species on LDH are the main active sites to construct H-bridges, then H-bridges induce the rapid and numerous electron transfer. The number of electron transfers in NCETP has increased by 2.58 times compared with that in traditional ETP. The antibiotic can be degraded within 30 min, and the whole system exhibits strong stability and anti-interference ability. This study offers valuable insights into the ETP mechanism in Fenton-like reaction, showcasing their promising potential in water treatment applications.
