Synthesis and Photo-catalytic Properties Characterization of Graphene/TiO2 Nano-tube Composites
Selecting graphene oxide (GO) and the Degussa P25 TiO2 (80% anatase and 20% rutile) as raw materials,the composites of graphene/TiO2 nano-tubes were simply and quickly prepared under the conditions of a concentrated solution of sodium hydroxide.The as-obtained composites phase structure was analyzed and characterized by powder X-ray diffraction (XRD),their morphologies were also observed and cross-confirmed under the Transmission Electron Microscopy (TEM).The measurements showed that the composites prepared in this work have a remarkable structure,and compared to the seperate TiO2 nano-tubes,the agglomeration of TiO2 nano-tubes covered on the surface of the graphene is apparently not so serious.In view of this,we preliminary tested the composites photo-catalytic performance with the visible light irradiation,and also made a comparison with TiO2 nano-tubes.
