Abstract

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.
