The magnetic Fe-MOFs derivatives obtained by high-temperature calcination under inert atmosphere have been studied and acted as high-efficiency catalysts in wastewater remediation. However, due to the shortcoming that the unstable structure of Fe-MOFs derivatives tends to collapse and agglomerate easily, it is necessary to find a support to improve its dispersibility and stability. In this work, an effective method was provided to fabricate biochar-loaded MIL-53(Fe) derivatives (BC@FexC) to activate peroxydisulfate (PDS) for norfloxacin (NOR) degradation. The efficiency of the BC@FexC/PDS system for NOR removal can reach to 91.2% within 15 min, and the reaction constant (k) was 52.15 times of BC/PDS and 22.19 times of FexC/PDS. Characterization results illustrated that the superior spatial pore structure and exposed active sites of BC@FexC allowed NOR to diffuse and interact with the catalyst efficiently. OH, SO₄⁻ and ¹O₂ were the main reactive oxygen species involved in NOR degradation. Moreover, the BC@FexC/PDS system exhibited excellent stability that almost unaffected by various environmental conditions (such as tap water, river water, and medical wastewater), which would provide a reference path for application in actual water treatment.

研究了惰性气氛下高温煅烧得到的磁性Fe-MOFs衍生物，并将其用作废水修复的高效催化剂。然而，由于Fe-MOFs衍生物结构不稳定，容易崩塌、团聚等缺点，需要寻找载体来提高其分散性和稳定性。在这项工作中，提供了一种有效的方法来制备生物炭负载的 MIL-53(Fe) 衍生物 (BC@FexC) 以激活过氧二硫酸盐 (PDS) 以降解诺氟沙星 (NOR)。BC@FexC/PDS体系对NOR的去除效率在15 min内可达91.2%，反应常数（k）是BC/PDS的52.15倍，FexC/PDS的22.19倍。OH、SO ₄ ^-和¹ O ₂是参与NOR降解的主要活性氧物质。此外，BC@FexC/PDS系统表现出优异的稳定性，几乎不受各种环境条件（如自来水、河水、医疗废水）的影响，为实际水处理应用提供了参考路径。
