Abstract
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.
