摘要：Metal-organic frameworks (MOFs) derived materials have been demonstrated to be promising alternatives for wastewater treatment. In this study, carbon supporting CuCo nanospheres (CuCo@C) with highly exposed active sites derived from bimetallic CuCo-MOF-74 presented excellent stability with continuous five cyclic reaction. The CuCo@C exhibited a highly efficient catalytic performance towards peroxymonosulfate (PMS), whereas 100% removal efficiencies of oxytetracycline (OTC), tetracycline (TC), methylene blue (MB), and Orange G (OG) were achieved while 89.5% of phenanthrene (PHE) removal efficiency was obtained with extremely low CuCo@C loading (40.0 mg/L) in 15 min. Results from this study suggested that synergistic effects between Cu and Co and the fast regeneration of low-valence metal promoted the heterogeneous activation of PMS to generate SO 4 ?? , · OH and 1 O 2 . Besides, carbon played a vital role in the improvement of CuCo@C stability. The high Fukui nucleophilic ( f ? ) index and quantitative structure-activity relationship (QSAR) indicated the preferred attacking sites and toxicity reducing of OG, respectively. Moreover, main intermediate products of OG were detected and the possible degradation pathway was proposed. The excellent catalytic performance, reduced toxicity of pollutants, good stability and reusability of CuCo@C all suggested the great application potential in practical water treatment. ? 2022, The Authors.
