Atomically dispersed catalysts anchored on nitrogen-rich substrates present promising application potential for the persulfate-based advanced oxidation process. Nevertheless, efficient activation efficiency and a clear activated mechanism of persulfate remain challenging in carbon nitride-based single-atom (SACs). To these, combined with regulation strategy metal–ligand section carrier's architecture, an atomically Co catalyst regular hollow tubular nitride (Co/TCN SAC) herein was devised utilized to activate permonosulfate. As result, Co/TCN SACs show excellent catalytic performance degradation common antibiotics. Combined X-ray absorption fine structure theory calculation, it is confirmed that superficially CoO3 sites Co2N2O2–CoO3 unit are active center peroxymonosulfate (PMS) activation. The electrochemical test situ electron paramagnetic resonance results demonstrate radical (SO4•– •OH) nonradical (electron transfer process 1O2) paths contributing superior performance. In addition, exhibits high reaction structural stability considering water quality parameters. Finally, continuous device operated laboratory scale, which exhibited satisfactory continuously removing electron-rich antibiotics such as tetracycline. This work reveals atomic-level modulation cobalt atomic their structure–activity relationship
