Co-doped carbon nitride (CoCN-6NH4Cl) was prepared through an NH4Cl-assisted pyrolysis method. The catalyst exhibits enhanced and persistent activity toward peroxymonosulfate (PMS) activation for antibiotic degradation under visible light. levofloxacin (LEV) removal efficiency reaches 89.1% within 60 min, much higher than that of the (CoCN) without addition NH4Cl (65.0%). Moreover, decay LEV after four cycles over CoCN-6NH4Cl is only 7.6%, in contrast to 21.8% CoCN. can be attributed remarkably increased specific surface area expose more active sites as well modified electronic structure caused by Cl doping. improved charge separation results generation photogenerated holes (h+), superoxide radicals (·O2–), singlet oxygen (1O2) main species participating degradation, thus greatly promoting efficiency. This work provides a facile effective strategy develop high-performance catalysts advanced oxidation processes.
