In this study, visible-light-driven cobalt ferrite/graphitic carbon nitride photocatalyst was successfully synthesized via precipitation technique. Cobalt ferrite were decorated on the surface of as-prepared g-C3N4 nanosheets via the precipitation technique. The structure, morphology, optical, and magnetic properties of the samples were studied by various techniques, The photocatalytic capability was assessed against methylene blue (MB) dye as a model pollutant under visible light irradiation. Compared to pure CoFe2O4 and gC3N4 nanostructures, the cobalt ferrite/graphitic carbon nitride nanocomposite showed higher photodegradation of MB. This showes the formation of heterojunction structure at the interface of CoFe2O4 and g-C3N4 leads to improved photocatalytic activity. Additionally, an external magnetic field was able to be used to separate the nanocomposite from the treated solution due to the magnetic properties of the CoFe2O4 component. The present study offers a facile method for designing CoFe2O4/g-C3N4 nanocomposite as a photocatalyst with high efficiency and good separability for environmental remediation applications.
