Simple fabrication of RGO/TiO2 nanocomposite with homogenous dispersion

Homogeneous dispersed RGO/TiO2 nanocomposite was synthesized using precursors of graphene oxide (GO) and Ti(SO4)2 and reducing agent of urea solvent by situ hydrothermal reduction method. The X-ray diffractometer (XRD) and fourier transform-infrared (FTIR) spectra were used to characterize the microstructure of RGO/TiO2 nanocomposite, and transmission electron microscope (TEM) and fieldemission scanning electron microscope (FESEM) were used observe the microtopography of RGO/TiO2 nanocomposite. The effect of urea mass ratio on number of TiO2 in RGO/TiO2 nanocomposite was investigated. It is revealed that the TiO2 nanoparticles efficiently disperse on the surface of RGO (reduced graphene oxide) sheets and RGO/TiO2 has close interfacial contact.
