摘要：Recently, the carbon materials with metal-N x sites or carbonyl (C=O) have attracted extensive attention in the degradation of organic pollutants by activated peroxymonosulfate (PMS). However, the synergistic mechanism of different sites for PMS activation is not clear. In this study, COF-derived carbon materials (Co-C500 COF ) with abundant C=O and ultra-small Co particles were synthesized by simple hydrothermal and calcination. Theoretical and experimental results revealed that the introduction of cobalt species formed the Co-N x site, which was beneficial to the release of C=O which originally blocked by N group in COF. The results indicated that Co-C500 COF showed excellent catalytic activity and cycle stability in the degradation of a variety of typical antibiotics for PMS activation. The Co-C500 COF /PMS system also maintained the incredible degradation effects in a wide pH range (3-9) and complex water environment with ion interference, which made it more potential for industrial application. The synergistic activation of PMS by C=O and Co-Nx sites had been proved to be the key to obtain excellent antibiotics degradation activity. Our results not only proposed the composite system of double active sites, but also providing new insights for further related studies. ? 2022, The Authors. All rights reserved.
