One-step hydrothermal synthesis of magnetic responsive TiO2 nanotubes/Fe3O4/graphene composites with desirable photocatalytic properties and reusability

Abstract

Here, we report a facile approach to preparing a magnetic responsive TiO2 nanotubes/Fe3O4/graphene composite (TNTs/Fe3O4/GN), in which the reduction of graphene oxide as well as the formation of Fe3O4 nanoparticles and TNTs occurred simultaneously. The preparation time and procedure were effectively simplified and shortened. A series of techniques including XRD, TEM, BET, VSM and EDX were employed to characterize the composite. Also, the photocatalytic activity of the composite was evaluated via the removal of methylene blue. The results showed that TNTs and Fe3O4 nanoparticles were deposited on layers of GN, and a synergistic effect was observed in the composite. Owing to interfacial contact between TNTs and GN, the recombination of photogenerated electrons/holes was suppressed and the photocatalytic performance was enhanced. The composite not only displayed higher photocatalytic activity than TNTs and P25, but also exhibited desirable reusability and rapid separation performance, which make it a potential candidate for applications in wastewater treatment.
