Scholarcy highlights

  • The nanocomposites of TiO2graphene have been prepared via a facile hydrothermal reaction of graphene oxide and TiO2 in an ethanol−water solvent
  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • We show that such a TiO2−GR nanocomposite exhibits much higher photocatalytic activity and stability than bare TiO2 toward the gas-phase degradation of benzene, a volatile aromatic pollutant in air
  • By investigating the effect of different addition ratios of graphene on the photocatalytic activity of TiO2−GR systematically, we find that the higher weight ratio in TiO2−GR will decrease the photocatalytic activity
  • The key features for TiO2−GR including enhancement of adsorptivity of pollutants, light absorption intensity, electron−hole pairs lifetime, and extended light absorption range have been found in the composite of TiO2 and carbon nanotubes. These strongly manifest that TiO2−GR is in essence the same as other TiO2−carbon composite materials on enhancement of photocatalytic activity of TiO2, graphene by itself has unique structural and electronic properties
  • We propose that TiO2−GR cannot provide truly new insights into the fabrication of TiO2−carbon composite as high-performance photocatalysts
