摘要：

By using tetrabutyl titanate as the main material, TiO2 nanoparticles/CNTs composite particles have been prepared in acidic abundant aqueous solution at low temperature without calcination. The microstructure of the composite particles, including surface morphology, phase composition and specific surface area was characterized by SEM, TEM, Raman, XPS and BET. The results reveal that TiO2 nanoparticles coated uniformly on CNTs surfaces were mainly anatase type. The surface roughness of CNTs was remarkably increased after coating. However, the specific surface area of composite particles decreased by 23.4 m2.g(-1) than that of CNTs with uncoated TiO2. Photocatalytic activity of TiO2 nanoparticles/CNTs composite particles shows a significant increase of absorption intensity both in ultraviolet band and visible light band according to UV-vis spectra.
