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;
H2O2 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.
