Abstract: Graphene-wrapped titanium dioxide nanoflower composites (G-TiO 2 ) consisting of nanosheets and nanoparticles were synthesized using a two-step solvo/hydrothermal process. Materials were characterized using SEM, TEM, high-resolution TEM (HRTEM), XRD, Raman spectroscopy, and FTIR.Further analysis was performed using Branauer-Emmett-Teller (BET) specific surface area analysis, electrochemical impedance spectroscopy (EIS), UV-Vis spectroscopy, and diffuse reflectance UV-Vis spectroscopy. Photocatalytic activity w… Show more

“…For both graphene and reduced graphene oxide composites, the electrons in TiO 2 generated by photons can be moved across the carbon sheets, which reduce the recombination of photon-generated electron-holes [18]. These kinds of materials have a high adsorption capacity, which enhances the photocatalytic performance of TiO 2 nanoparticles [19].…”
