FeS_x@MoS₂-x (FM-x, x implied real Mo/Fe content ratios) in which FeS_x derived from MIL-88A deposited on the surface of MoS₂ with a tight heterogeneous interface were synthesized for peroxymonosulfate (PMS) activation to degrade atrazine (ATZ). The catalytic performance of FM-0.96 was greatly improved due to the rapid regeneration of Fe²⁺ resulting from the interfacial interaction. FM-0.96 could completely degrade 10.0 mg/L ATZ within 1.0 min, and the toxicities for most of its intermediates were greatly reduced. The k value of FM-0.96 was 320 and 40 times higher than that of the MoS₂ and FeS_x, respectively. The SO₄·⁻, ·OH and ¹O₂ were mainly responsible for ATZ degradation in FM-0.96/PMS system, and the conversion pathway of ¹O₂ was analyzed. Furthermore, the long-term continuous operation for ATZ degradation was achieved using a fixed membrane reactor. This work provides deep insights into metal sulfide composites derived from metal-organic frameworks for removing pollutants by activating PMS.

FeS _x @MoS ₂ -x（FM-x，x 表示真实的 Mo/Fe 含量比），其中合成了源自 MIL-88A 的 FeS _x沉积在具有紧密异质界面的 MoS ₂表面，用于过氧单硫酸盐 (PMS) 活化降解阿特拉津 (ATZ)。由于界面相互作用导致Fe ²⁺快速再生，FM-0.96的催化性能得到了极大的提高。FM-0.96可在1.0 min内完全降解10.0 mg/L ATZ，大部分中间体的毒性大大降低。FM-0.96 的k值分别是MoS ₂和FeS _x的320 倍和40 倍。SO ₄· ⁻、·OH和¹ O ₂是FM-0.96/PMS体系中ATZ降解的主要原因，分析了¹ O _{2的转化途径。}此外，使用固定膜反应器实现了 ATZ 降解的长期连续运行。这项工作为通过激活 PMS 去除污染物的金属有机框架衍生的金属硫化物复合材料提供了深刻的见解。
