AB  - Peroxymonosulfate decomposition is crucial for environmental remediation, especially in degrading organic pollutants. Peroxymonosulfate can be oxidized by transition metals, generating hydroxyl and sulfate radicals that degrade pollutants. In this study, a heterogeneous catalyst (Fe3O4@N-MWCNT, a composite of Fe3O4 with nitrogen-doped multi-walled carbon nanotubes) was prepared, characterized (FT-IR, TEM, XRD, DSC), and used as a peroxymonosulfate activator for the degradation of Methylene Blue and Methyl Orange dyes in aqueous media. The results indicated that Fe3O4@N-MWCNT could serve as an effective peroxymonosulfate activator, reducing degradation times from hours to seconds (Methylene Blue: >180 min. to 32 s; Methyl Orange: >20 min. to 6 s). Moreover, the Fe3O4@N-MWCNT catalyst maintained its activity over 5 cycles. This study demonstrated that Fe3O4@N-MWCNT can serve as a highly effective activator of peroxymonosulfate, thereby holding significant potential for remediating water sources contaminated with Methylene Blue and Methyl Orange dyes.
