Abstract

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.
