摘要

CoFe2O4@Fe0纳米催化剂来源于外延生长的S-BUC-21(Fe)@ feo - pba MOF-on-MOF前体，通过过氧单硫酸盐活化，在5分钟内完全降解了阿特拉津。机制研究揭示了自由基/非自由基的协同作用途径，而对狗尾草和印度莲子幼苗的植物毒性试验证实了降解产物的环境安全性。这项工作提出了一种高效、环保的水净化解决方案。

MOF-on-MOF Derived Magnetic CoFe2O4@Fe0 Nanocomposites for Ultra-Rapid Peroxymonosulfate Activation: Mechanistic Insights and Eco-Toxicological Validation

CoFe2O4@Fe0 nanocatalysts derived from epitaxially grown S-BUC-21(Fe)@FeCo-PBA MOF-on-MOF precursors achieved complete atrazine degradation within 5 minutes via peroxymonosulfate activation. Mechanistic studies revealed synergistic radical/non-radical pathways, while phytotoxicity tests with Setaria viridis and Eleusine indica seedlings confirmed the environmental safety of degradation products. This work presents an efficient, eco-friendly solution for water purification.
