TiO2/Fe3O4/Graphene Nanocomposite: Synthesis, Characterization and Photodegradation of Methylene Blue

In this research, ternary magnetic Tio2/Fe3O4/Graphene nanocomposite containing different amounts of graphene (Gr) (0.015, 0.03, 0.06 and 0.12 g) have been successfully synthesized by facile hydrolysis procedure and characterized by XRD and FESEM tests. It is necessary to note that Fe3O4 nanoparticles (Nps) were synthesized by snochemical method. Morphology characterization test showed that TiO2 Nps and Fe3O4 Nps are both coated on the surfaces of graphene. The photocatalytic performance of the synthesized nanocomposites was studied for methylene blue (MB) degradation test under visible light. The degradation percent (DP %) of MB in presence of TiO2/Fe3O4/Gr nanocomposite containing maximum amount of graphene content (0.12 g) reached 76% in 90 min under visible light. Therefore one can use TiO2/Fe3O4/Gr nanocomposite in photocatalytic degradation of MB and other organic pollutants because of their good photocatalytic performance and also magnetic properties (which help their recycle).
