Synthesis and characterization of W-doped TiO₂ supported by hybrid carbon nanomaterials of multi-walled carbon nanotubes and C₆₀ fullerene by a hydrothermal method

Abstract

W-doped TiO₂ supported by hybrid carbon nanomaterials of multi-walled carbon nanotubes and C₆₀ fullerene was synthesized by a simple hydrothermal method. The material displayed high visible light photocatalytic activity. X-ray diffraction, field emission transmission electron microscopy, ultra violet/visible light absorption and photoluminescence spectroscopy were used to characterize the material as photocatalyst. Photocatalytic activity on the degradation of Rhodamine B dye in an aqueous solution under ultraviolet light and visible light irradiation was also studied. The experimental results indicated that the photocatalytic activity of the material was much higher than that of pure TiO₂ or Degussa P25 TiO₂.
