The heterogenous photo-Fenton technology has been widely applied in the field of water treatment due to its characteristic of environment friendly and no generation of iron sludge. However, the unsatisfied photogenerated charge separation and transfer efficiency quite limited the catalytic activities of the photo-Fenton materials. Herein, the MoS₂/FeOCl (MS/FOC) heterojunction was synthesized by an ingenious ultrasonic method. The photo-Fenton catalytic activities were evaluated by the degradation of dye and antibiotic pollutants in the water. With the assistance of the MS, the MS/FOC performed the enhanced charge transfer efficiency compared with the pure FOC. As the result, more photogenerated electron could gathered on the FOC and further boosted Fenton reaction to generate more hydroxyl radical (•OH) for high-performance degradation of water pollutants. This work provides a new insight into the design and synthesis of the novel photo-Fenton catalyst for the high-efficiency water treatment in future.

非均相光芬顿技术由于具有环境友好、不产生铁泥等特点，在水处理领域得到了广泛的应用。然而，不令人满意的光生电荷分离和转移效率极大地限制了光芬顿材料的催化活性。其中，MoS ₂/FeOCl (MS/FOC) 异质结是通过巧妙的超声方法合成的。通过水中染料和抗生素污染物的降解来评估光芬顿催化活性。在 MS 的帮助下，与纯 FOC 相比，MS/FOC 的电荷转移效率更高。结果，更多的光生电子可以聚集在 FOC 上，进一步促进 Fenton 反应生成更多的羟基自由基 (•OH)，从而实现水污染物的高效降解。这项工作为未来用于高效水处理的新型光芬顿催化剂的设计和合成提供了新的视角。
