Abstract
Graphene oxide (GO) was prepared by modified Hummers method from different carbon sources: expanded graphite and 4, 8, 12-pellets graphene. GO samples were studied by Scanning Electron Microscopy, Transmission Electron Microscopy, Raman Spectroscopy, Xray diffraction and UVevis spectroscopy. Then, GO was used to obtain TiO2/GO nanocomposite electrodes via electrochemical deposition process. Titanium dioxide nanotubes (TiO2NT) were obtained via anodization in electrolyte containing ethylene glycol with 1 wt % NH4F. Different conditions of deposition process of GO were examined. The resulting electrodes were characterized by SEM, TEM, X-ray diffraction, UVevis spectroscopy and electrochemical methods. The results have shown that the expanded graphite is a good carbon source to synthesize highly oxidized graphene oxide. The composite electrodes have interesting electrochemical properties and are promising materials for photoanodes. Copyright © 2016, Hydrogen Energy Publications, LLC. Published by Elsevier Ltd.
