Normal spinel structure ZnFe_2O_4/g-C_3N_4 enhanced catalytic activity for photo-Fenton degradation of methylene blue

摘要

Heterogeneous photo-Fenton technology has been widely employed to degrade organic dyes in wasterwater. In the present study, a composite consisting of normal spinel structure ZnFe2O4 nanoparticle and two-dimensional sheet of g-C3N4 was facilely synthesized. Different characterization technologies, such as XRD, XPS and VSM, were employed to demonstrate the normal spinel structure ZnFe2O4 formation. The composite shows higher catalytic activity for degradation of methylene blue (MB) than mixed spinel structure ZnFe2O4 /g-C3N4 . Simultaneously, the composite exhibits excellent stability and reusability.
