Peroxymonosulfate (PMS) has attracted great interest over the past few years owing to its capacity and versatility for breakdown of developing antibiotic contaminants. It is under intensive investigation potential alternative advanced oxidation processes (AOPs) in wastewater treatment. In this study, we used activated cobalt-doped carbon as a new excellent metal catalyst activate PMS. The synthesis novel Co3O4@C-900 hybrids with numerous active interfaces superior surface electron transfer was achieved. matrix mixed evenly create stable catalytic structure. structure equipped them enhanced efficacy, thus decreasing environmental harm during actual Chlortetracycline (CTC) degradation. CTC removal rate reached 100% within 10 min, exhibiting outstanding stability high efficiency hybrids. Additionally, elucidated PMS activation mechanism by via paramagnetic resonance (EPR) spectroscopy, radical quenching studies, characterization analyses. Free experiments EPR spectroscopy revealed that degradation system concomitant process free-radical non-radical reactions. reactions were based on generate O2-, SO4- OH, whereas C species 1O2. Therefore, study presents promising candidate also demonstrates
