Facile synthesis of carbon dots-coated CuFe2O4 nanocomposites as a reusable catalyst for highly efficient reduction of organic pollutants

摘要

In this work, a carbon dots (CDs)-coated CuFe2O4 (CuFe2O4-CDs) nanocomposite consisting of magnetic CuFe2O4 core and CDs shell was synthesized via a facile one-pot solvothermal strategy. The CuFe2O4-CDs nanocomposite was characterized by TEM, XRD, XPS, TGA and VSM. Due to the protection of the CDs layer, the CuFe2O4-CDs exhibits excellent reusability and outstanding catalytic activity which is far superior to similar materials in catalytic reduction of 4-nitrophenol (4-NP), Methylene blue (MB) and Rhodamine B (RhB). The results suggested that the CuFe2O4-CDs nanocomposites have promising potential as an efficient and reusable catalyst for water environment treatment.
