A novel direct Z-scheme magnetic organic polymer gel decorating Ag₃PO₄ (Ag₃PO₄/Fe₃O₄/MP) photocatalyst was facilely synthesized by an in-situ method. Fe₃O₄/MP nanoparticles were randomly distributed on the surface of Ag₃PO₄ without blocking the structure completely. The Ag₃PO₄/Fe₃O₄/MP composite demonstrated enhanced photocatalytic performance for degradation of pollutants such as tetracycline (TC) and 4-Chlorophenol (p-CP). In addition, the photocatalyst has good recyclability and could be easily separated from the solution with the help of magnetic field. Finally, results of the trapping experiments indicated that O₂⁻, holes, and OH were the major reactive species and the enhanced activity originated from the excellent synergistic effect between Ag₃PO₄ and Fe₃O₄/MP nanoparticles, forming a direct Z-scheme photocatalytic system.

通过原位合成方法，简便地合成了一种新型的Z型磁性有机高分子凝胶修饰的Ag ₃ PO ₄（Ag ₃ PO ₄ / Fe ₃ O ₄ / MP）光催化剂。Fe ₃ O ₄ / MP纳米颗粒随机分布在Ag ₃ PO ₄的表面上，而没有完全封闭结构。Ag ₃ PO ₄ / Fe ₃ O ₄/ MP复合材料对四环素（TC）和4-氯苯酚（p-CP）等污染物的降解具有增强的光催化性能。另外，光催化剂具有良好的可回收性，并且可以在磁场的帮助下容易地与溶液分离。最后，捕获实验的结果表明，直径：₂ ^- ，孔，和O H，分别为主要活性物质和增强的活性源于优异的协同效果的Ag之间₃ PO ₄和Fe ₃ ö ₄ / MP纳米颗粒，从而形成直接Z方案光催化系统。
