%X The successful preparation of immobilized nitrogen-doped carbon/cobalt @ porous spherical substrate (N-C/Co@PSS) catalyst derived from ZIF-67 was reported in this work. The oxytetracycline (OTC), tetracycline (TTC), and chlortetracycline (CTC) in the simulated wastewater were decomposed via the peroxymonosulfate (PMS) activation by N-C/Co@PSS. The degradation of TCs was initially investigated by batch-type experiments, in which ca. 100% TCs with an initial concentration of 10.0 mg L-1 can be degraded over N-C/Co@PSS + PMS system within 15 min for 30 runs’ operation. In addition, detailed non-radical dominating degradation mechanism was explored by active species capture experiments, electron spin resonance (ESR) tests and electrochemical technology. Furthermore, continuous degradation of TCs antibiotics for up to 200 h in the packed N-C/Co@PSS fixed bed reactors could be accomplished. This work provides theoretical and technical support for the application of MOFs-based catalysts in large-scale wastewater remediation.
