The regulation of heterogeneous material properties to enhance the peroxymonosulfate (PMS) activation degrade emerging organic pollutants remains a challenge. To solve this problem, we synthesize S-scheme heterojunction PBA/MoS2@chitosan hydrogel achieve photoexcitation synergistic PMS activation. constructed photoexcited carriers undergo redox conversion with through transfer pathway driven by directional interface electric field. Multiple pathways greatly reactive oxygen species generation, leading significant increase in doxycycline degradation rate. Meanwhile, 3D polymer chain spatial structure chitosan is conducive rapid capture and electron transport advanced oxidation process, reducing use transition metal activator limiting leaching ions. There reason believe that regulated will provide new perspective for future design research on enhancing heterologous catalysis process.
