Summary: This study presents a visible-light-driven organic-inorganic S-scheme heterostructure photocatalyst with excellent performance in removing antibiotics from wastewater. By anchoring TCPP on the surface of Bi12O17Cl2, the S-scheme junction between TCPP and Bi12O17Cl2 was created, enhancing the visible-light response and accelerating the disintegration and conservation of photo-carriers. The resulting TCPP/Bi12O17Cl2 showed significantly improved photocatalytic activity and stability compared to Bi12O17Cl2. Through scavenging tests, LC-MS analysis, and toxicity calculation, the reactive radicals, degradation pathway, and eco-toxicity were elucidated. This research demonstrates the potential practicality of porphyrin-based S-scheme heterojunction photocatalysts for efficient antibiotic removal.
