摘要：

Highly photoactive, graphene-wrapped anatase TiO 2 nanoparticles are synthesized through one-step hydrothermal reduction of graphene oxide (GO) and TiO 2 crystallization from GO-wrapped amorphous TiO 2 NPs. Graphene-TiO 2 nanoparticles exhibit a red-shift of the band-edge and a significant reduction of the bandgap (2.80 eV). Graphene-TiO 2 nanoparticles possess excellent photocatalytic properties under visible light for the degradation of methylene blue. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
