Phenol and its derivatives are among the dangerous pollutants usually found in the wastewater of petrochemical and pharmaceutical industries. Photodegradation is one of the most promising techniques to treat phenol-polluted wastewater. The lack of reusability of the photocatalyst and their high agglomeration tendency have reduced its stability and efficiency. To address these limitations, a binary nanocomposite of Fe₃O₄@SiO₂ was synthesized in this study to be used as an active photocatalyst for the photodegradation of phenol under UV irradiation. Numerous physicochemical characterizations were performed to study the morphology, crystallinity, thermal stability of the prepared nanocomposite. These techniques confirmed the effective fusion of the two entities in the newly formed nanocomposite. The efficiency of the photocatalysts was steadily enhanced over the period investigated in this study. The phenol degradation efficacy of 84% was accomplished using Fe₃O₄@SiO₂ composite, which was higher as compared to that of single Fe₃O₄ (59%). The newly prepared materials can be effectively recycled by facile magnetic separation method.

苯酚及其衍生物是石化和制药行业废水中常见的危险污染物。光降解是处理苯酚污染废水的最有前途的技术之一。缺乏光催化剂的可重复使用性及其高聚集趋势降低了其稳定性和效率。为了解决这些局限性，Fe ₃ O ₄ @SiO ₂的二元纳米复合材料在这项研究中被合成用作活性光催化剂，以在紫外线照射下光降解苯酚。进行了许多物理化学表征以研究所制备的纳米复合材料的形态，结晶度，热稳定性。这些技术证实了新形成的纳米复合材料中两个实体的有效融合。在此研究期间，光催化剂的效率稳步提高。使用Fe ₃ O ₄ @SiO ₂复合材料可实现84％的苯酚降解效率，比单一的Fe ₃ O ₄（59％）更高。新制备的材料可以通过磁分离方法有效地回收利用。
