Tetracycline degradation mechanism of peroxymonosulfate activated by oxygen-doped carbon nitride.

ABSTRACT: In this study, oxygen-doped carbon nitride (O-C₃N₄) was prepared by thermal polymerization and was applied to activate peroxymonosulfate (PMS) for tetracycline (TC) degradation. Experiments were performed to comprehensively evaluate the degradation performance and mechanism. The oxygen atom replaced the nitrogen atom of the triazine structure, which improves the specific surface area of the catalyst, enriches the pore structure and achieves higher electron transport capacity. The characterization results showed that 0.4 O-C₃N₄ had the best physicochemical properties, and the degradation experiments showed that the 0.4 O-C₃N₄/PMS system had a higher TC removal rate in 120 min (89.94%) than the unmodified graphitic-phase C
