摘要：

Ternary graphene-Fe3O4:TiO2 nanocomposites (GF:TiO2) were successfully prepared by a hydrothermal method. Characteristics of the nanocomposites were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and UV-visible spectroscopy (UV-vis). Photocatalytic activity evaluated by degradation of methylene blue (MB) under UV and visible light determined the efficiency of GF:TiO2 at a ratio of 1:4, reaching 88.11% and 90.52% in 90 min under UV and visible light respectively. Enhanced visible light photocatalytic activity for degradation of MB was mainly attributed to the two dimensional structure of graphene as a good electron acceptor and transporter.
