| description | The urgent need to address contaminated antibiotics poses a threat to human health and natural systems and has led to the advancement of advanced oxidation processes (AOPs). This study presents a improvement in tetracycline (TC) elimination by engineering g-C _3 N _4 microtubes with co-doping of boron and manganese (CNBMn), endowing effectively photogenerated carrier under visible light in the presence of peroxymonosulfate (PMS). The optimized CNBMn2 composition (0.25 mmol boric acid, 0.5 mmol MnCl _2 , 0.01 mol cyanuric acid, 0.01 mol melamine) achieved 99% TC removal within 40 min under visible light with 0.75 g l ^−1 catalyst and 1.5 mM PMS. Furthermore, remarkable stability is achieved with >80% TC removal over six consecutive cycles, owing to a well-engineered stable structure of CNBMn2. The enhanced performance of CNBMn2 promotes the generation of reactive oxygen species (ROS), including sulfate radicals (SO _4 ^·− ), hydroxyl radicals ( ^· OH), superoxide radicals (O _2 ^·− ), hole (h ^+ ) and singlet oxygen ( ^1 O _2 ) in the presence of PMS and light, leading to significant TC degradation. The effects of various factors on the system, such as PMS concentration, ion matrix, catalyst dosage, and initial pH, were also examined. This work highlights the architectural control and concurrent doping of foreign atoms in g-C _3 N _4 , specifically for purifying antibiotic-contaminated water, representing a significant advancement in water treatment technologies. |
