Core-shell magnetic CFO@COF composites toward peroxymonosulfate activation for degradation of sulfamethoxazole from aqueous solution: A comparative study and mechanistic consideration.

A core-shell covalent organic framework encapsulated CoFeO magnetic particles (CFO@COF) was designed and prepared successfully to activate peroxymonosulfate (PMS) for sulfamethoxazole (SMX) degradation. It displays amazing catalytic reactivity since the unique interior structure and synergistic effect between COF shell and CFO core, reaching 99.8% removal of SMX (10 mg/L) within 30 min and 90.

ZrO supported perovskite activation of peroxymonosulfate for sulfamethoxazole removal from aqueous solution.

In this study, A- and B-site doped perovskite LaSrCoNiO （LSCN) was prepared by sol-gel method. On this basis, ZrO supported LSCN used to maintain high catalytic activity while inhibit the leaching of toxic Co ions. Compared with the non-doped LaCoO, the ZrO@LaSrCoNiO (Z@LSCN82)/PMS system could almost completely degrade SMX in 30 min.
