Graphene-Fe3O4-TiO2 ternary composite: an efficient visible light catalyst for the removal of organic pollutants

Abstract

A facile synthesis technique was employed for producing magnetic graphene-TiO2 photocatalyst (GO-Fe3O4-TiO2). The synthesis method involves combination of sol-gel and assembling processes. The magnetic composite was characterized by, XRD, SEM, FESEM and UV-DRS analysis. The as synthesized material showed higher photocatalytic activity towards methylene blue (MB) degradation as compared with that of pure TiO2 and GO-Fe3O4 nanocomposite. Magnetic property of the nanocomposite defines it to be easily separable for repeated applications. These attractive physical properties and efficient photocatalytic activity quote GO-Fe3O4-TiO2 nanocomposite as a promising photocatalyst under sunlight for practical use in wastewater treatment to control water pollution.
