Characterization and Enhanced Visible-Light Photocatalytic Properties of {001} Facets-Exposed TiO2-Reduced Graphene Oxide Nanocomposites.The efficient visible-light active nanocomposites of {001} facets-exposed TiO2-reduced graphene oxide (RGO) were fabricated by a simple one-step solvothermal approach for application in photocatalytic degradation.  The incorporation of RGO with TiO2 increased the light absorption in the whole visible region and displayed a red-shift absorption edge, accelerated the separation of photogenerated electron-hole pairs, furthermore, effectively enhanced the photocatalytic activity of TiO2 under the visible light.
