▎ 摘　　要

Different graphene (GR)-modified morphologies of TiO2 including nanoparticles, nanorods and nanowires were prepared by a simple and efficient electrostatic self-assembly method followed by a hydrothermal reduction process. Characterisations reveal that different morphologies of TiO2 are distributed on GR and that they decrease the electron-hole recombination rate and extend the light absorption range compared with pure TiO2. The as-prepared different morphologies of GR-modified TiO2 nanocomposites are used to photodecompose bisphenol-A in water under visible-light irradiation. All morphologies of TiO2 anchored onto the surface of a GR sheet exhibit higher photocatalytic activity under irradiation than pure TiO2. Photocatalytic activity is also increased by the increase in length of TiO2 distributed on GR. The photodegradation activities of all GR/TiO2 nanocomposites are stable under light after three successive cycles.
