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 $•{\mathrm{O}}_2^{-}$, and Pyridinic N promoted the conversion of $•{\mathrm{O}}_2^{-}$ 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 recyclability. This work provides novel insights for generating ¹O₂ by activation of PMS for environmental remediation.

在这项研究中，通过使用N掺杂多孔碳和Fe纳米颗粒（NPC-Fe）活化过一硫酸盐（PMS），实现了1 O 2 的特定生成，该纳米颗粒是通过碳化用离子改性的MIL-88B（Fe）金属有机框架^合成的_。液体。发现催化剂中的 Fe(II) 与 PMS 反应生成$•{\mathrm{氧}}_2^{-}$，吡啶N促进了转化$•{\mathrm{氧}}_2^{-}$至¹ O ₂。因此，NPC-Fe/PMS反应系统可以通过Fe(II)和吡啶N的协同作用产生大量的¹ O ₂ 。该系统在较宽的pH范围内对以抗生素为代表的污染物的降解表现出优异的性能。此外，催化剂NPC-Fe具有良好的稳定性和可回收性。这项工作为通过激活 PMS生成¹ O _{2进行环境修复提供了新的见解。}
