In this study, a novel copper nanozyme (CNZ) was synthesized by a mild way and characterized by scanning electron microscopy and Fourier transform infrared spectroscopy (FTIR). The as-fabricated CNZ exhibited typical peroxidase activity toward 2, 2'-azinodi-(3-ethylbenzthiazoline)-6-sulfonate. We successfully applied CNZ for the degradation of methyl orange pollutants. Under the optimum conditions (pH, 3.0; T , 60 °C; H 2 O 2 concentration, 200 mM; dosage of CNZ, 8 mg), 93% of the degradation rate could be obtained in less than 10 min. Furthermore, the nanozyme exhibited excellent reusability and storage stability. All these experimental results suggested that CNZ is a powerful catalyst for industrial wastewater treatment.
