Facile Synthesis of CeMOFs-Graphene Oxide Composites for Photocatalytic Degradation of Methylene Blue

Abstract

CeMOF-graphene oxide (GO) composite (CeMOF-nGO, n=1, 5, 9, corresponding to the percentage of GO at 1, 5 and 9%) was synthesized through a facile synthesis method at room temperature. The parent and composite materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA) and N 2 adsorption-desorption isotherms. Their photocatalytic degradation of methylene blue in aqueous solution were systematically tested by Ultraviolet-Visible spectrophotometer (UV-Vis). The novel CeMOF-nGO materials exhibit an obvious photocatalytic degradation property and the CeMOF-5GO shows a remarkable catalytic ability in the degradation of methylene blue (86.62%) under visible light. In general, the combination of CeMOF and graphene oxide provides us a bright future to explore the unique properties of rare-earth MOFs-GO composites on degradation of organic pollution and many other fields.
