Facile synthesis of magnetically separable copper ferrite infused sulfonated graphene oxide nanocomposite with antimicrobial evaluation and photocatalytic performance under visible light

Facile approach has been employed for the synthesis of new copper ferrite impregnated sulfonated graphene oxide (SGO) nanocomposite via co‐precipitation technique. The newly created nanocomposite has exceptional qualities like a strong stability, large surface area, simple as well as effective recoverability. Structure, composition, and morphology of CuFe2O4@SGO nanocomposite were analyzed by fourier‐transform infrared spectroscopy (FT‐IR), scanning electron microscope (SEM), energy dispersive X‐Ray (EDX), X‐ray diffraction (XRD), and thermogravimetric analysis (TGA) techniques. The results presented the decoration of CuFe2O4 nanoparticles decorated uniformly upon the SGO sheets. Presently, photocatalytic efficiency of synthesized nanocomposite has been assessed for the deterioration of methyl violet 2B (MV) dye. On the effectiveness of dye degradation, the impacts of variables including initial dye concentration, catalyst loading, and visible light exposure have been studied. The photocatalytic data show that 97% of dye was degraded in merely 90 min. CuFe2O4@SGO nanocomposite was easily recyclable and hence it shows future scope as an inexpensive and alternate approach for removal of dye. The results of antimicrobial data evaluated that outstanding antibacterial data counter to Escherichia coli, Bacillus subtilis, and excellent antifungal data counter to Candida albicans was perceived.
