摘要：In this study, specific generation of 1O2 was achieved by activation of peroxymonosulfate (PMS) using N-doped porous carbon with Fe nanoparticles (NPC-Fe), synthesized by carbonizing MIL-88B(Fe) metal-organic frameworks modified with ionic liquid. Fe(II) in the catalyst was found to react with PMS to form & BULL;O2 ?, and Pyridinic N promoted the con-version of & BULL;O2 ? to 1O2. Consequently, the NPC-Fe/PMS reaction system could generate a large amount of 1O2 by the synergistic effect of Fe(II) and Pyridinic N. The system demonstrated excellent performance in a wide pH range for the degradation of contaminants represented by antibiotics. Additionally, the catalyst NPC-Fe had good stability and recy-clability. This work provides novel insights for generating 1O2 by activation of PMS for environmental remediation.
