Abstract

The present paper focusses on the synthesis of graphene oxide and its nanocomposite with metal organic framework (MOF-5). Graphene oxide (GO) was prepared using modified hummer’s method with different concentrations of oxidizing agent to vary the presence of functional group on the surface of GO. The presence of functional group plays a crucial role in determining the interactions between GO and MOFs. To confirm the presence of different functional groups on the surface of GO, structural and optical characterization were performed. The GO samples were used to successfully synthesize MOF5-GO nanocomposite which were studied for their structural, morphological and optical properties. FTIR and XRD analysis were performed to confirm the formation of nanocomposite. SEM was done to morphologically analyse the nanocomposite. UV-Visible spectroscopy was used to study the variation in the bandgap of samples. TGA was used to depict the thermal behaviour of GO and its nanocomposites with MOF5
