Eosin Y(EY)dye sensitized nanocomposite of TiO2 with graphene(T-G-EY)was prepared by hydrothermal process starting from EY,TiO2(P25)and graphene oxide(GO).X-ray photoelectron spectroscopy(XPS)measurement showed dramatically decrease in the content of oxygen-containing functional groups due to the reduction of GO in the hydrothermal process.Transmission electron microscopy(TEM)observation illustrated that the graphene in T-G-EY nanocomposite was relatively uniformly covered and anchored by P25.The nanocompos...
