摘要：
Highly efficient and easily recycled visible-light-driven g-C3N4/ZnFe2O4 heterostructured photocatalysts were prepared by a simple hydrothermal synthesis method. The composition, structure, morphology, and optical absorption properties of the as-prepared g-C3N4/ZnFe2O4 composites were characterized by X-ray diffraction, scanning electron and transmission microscopy, X-ray photoelectron spectroscopy, UV-vis diffuse reflectance spectroscopy, Photoluminescence (PL) spectra, Brunauer-Emmett-Teller (BET) and FTIR spectra, respectively. The result shows that we have found a phenomenon of different proportions of the g-C3N4/ZnFe2O4 composition, 1:2 fraction has the highest rate of the degradation of spiramycin under visible light irradiation. The composite catalyst has better photocatalytic activity, the compound has the characteristics of good stability and easy recycling. (C) 2016 Published by Elsevier B.V.
