| Popis | This study presented a streamlined, one-step hydrothermal method for synthesizing magnetic iron tungsten oxide (FeWO4/Fe3O4) composites, replacing the conventional two-step approach. The FeWO4/Fe3O4 catalysts obtained through this method exhibited a high surface area of 56.1 m2/g, which enables effective activation of Oxone, achieving 96 % degradation of sulfamethoxazole within 20 min. The magnetic properties derived from Fe3O4 facilitate the efficient recovery of the catalyst. Additionally, the inclusion of hydroxylamine enhanced the regeneration of Fe(II), thereby significantly increasing catalytic efficiency. The catalyst demonstrated strong reusability and stability, sustaining high degradation performance over six successive cycles. These findings underscore the potential of FeWO4/Fe3O4 as a promising magnetic catalyst for pollutant remediation in advanced oxidation processes. |
