Comparison of the photocatalytic effect of magnetic nanocomposites:CoFe۲O۴/g-C۳N۴ and CoFe۲O۴/CdS in the degradation of azo dyes

In this study, visible-light-driven cobalt ferrite/cadmium sulphide and cobalt ferrite/graphitic carbon nitride photocatalyst was successfully synthesized via precipitation technique. Cobalt ferrite were decorated on the surface of as-prepared g-C۳N۴ and cadmium sulphide 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 CoFe۲O۴ and gC۳N۴ and CdS nanostructures, the CoFe۲O۴/CdS and CoFe۲O۴/gC۳N۴ nanocomposite showed higher photodegradation of MB. An external magnetic field was able to be used to separate the nanocomposite from the treated solution due to the magnetic properties of the CoFe۲O۴ component. The present study offers a facile method for designing CoFe۲O۴/g-C۳N۴ nanocomposite as a photocatalyst with high efficiency and good separability for environmental remediation applications
