Abstract

N-doped graphene (NG)/TiO2 nanocomposite was synthesized via a facile one-step hydrothermal reaction. X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy analysis demonstrate that nitrogen atoms successfully doped into graphene structure. The photocatalytic activity of the obtained nanocomposite for the degradation of methylene blue (MB) was investigated, which showed better photocatalytic properties than graphene/TiO2 nanocomposite and N-doped TiO2. This work could provide new insight into the fabrication of TiO2-carbon nanocomposites as high performance photocatalysts and facilitates their application in addressing environmental protection issues.
