In this study, the novel composite materials of activated carbon (AC) and persulfate (PS) doped by nitrogen (N) sulfur (S) were successfully synthesized through one-step mechanical ball milling. Different from previous liquid-phase activation process PS, direct in situ solid-phase PS was achieved newly generated chemical bonds between AC PS. The increased crystal surface exposure highly electronegative atoms provided more reactive sites for modified composites, enabling them to extract electrons pollutant. Compared S doping, N-doped exhibited a higher oxidative degradation ability, with removal rate 93.6% tetracycline (TC, 40 mg/L) within min. interactions that occur interior avoid limitations mass transfer solid–liquid interface, thus expanding pH application range catalytic reaction minimizing interference other components solution. synergistic effect active oxygen species electron is main mechanism promoting pollutant degradation. This research puts forward new insight into approach proposes feasible method advanced treatment TC wastewater.
