Highly dispersive {001} facets-exposed nanocrystalline TiO2 on high quality graphene as a high performance photocatalystElectronic supplementary information (ESI) available. See DOI: 10.1039/c2jm16114a
A series of composites of nanocrystalline TiO 2 with exposed {001} facets and high quality graphene sheets (GS) were synthesized via a one-step hydrothermal reaction in an ethanolwater solvent. The obtained {001} facets-exposed TiO 2 /GS photocatalysts were characterized by Raman spectroscopy (RS),...

via
a one-step hydrothermal reaction in an ethanolwater solvent. The obtained {001} facets-exposed TiO

/GS photocatalysts were characterized by Raman spectroscopy (RS), X-ray photoelectron spectroscopy (XPS), X-ray diffraction pattern (XRD), field emission scanning electron microscopy (SEM), transmission electron microscopy (TEM), ultraviolet visible (UV-vis) diffuse reflectance spectroscopy (DRS) and Electrical Impedance Spectroscopy (EIS). They showed a better photocatalyst properties than P25 and other normal TiO

/GS composites, which could be explained on the basis of the formation of chemical TiOC bond and the formation of nano-sized Schottky interfaces at the contacts between TiO

and GS. The influence of the exposed {001} facets on the photocatalytic activity was investigated. The result showed that positively charged dye molecules are preferentially adsorbed onto the TiO
2
/GS composites due to the photogenerated charge gathered on GS. Overall, this work could provide new insights into the fabrication of TiO

carbon composites as high performance photocatalysts and facilitate their application in addressing environmental protection issues.
